Procedura per l’installazione
Uso
Uso
Tutte le istruzioni per il corretto funzionamento delle pompe VacIon
Plus sono contenute nel manuale dell'unità di controllo. Leggere
attentamente tale manuale prima dell'utilizzo. Si raccomanda di
portare la pompa ad una pressione di 1x10-4 Torr (mbar) in modo da
ottenere un avvio più rapido. A questo scopo è meglio non utilizzare
una pompa meccanica sigillata con olio, ma se deve essere utilizzata
una tale pompa, si raccomanda di inserire una trappola lungo la linea
di vuoto per ridurre la pressione causata dai vapori di acqua e di olio
provenienti dalla pompa meccanica. Cercare di ridurre al minimo il
tempo in cui la pompa meccanica è aperta verso il sistema e verso la
pompa ionica, poiché i suoi vapori si diffondono nel sistema a
pressioni inferiori a 1x10-1 Torr (mbar) causando una
contaminazione dello stesso. Nei sistemi in cui l’olio deve essere
completamente assente, è meglio utilizzare pompe Turbo per la
suddetta operazione. Depositi igroscopici e l’assorbimento
dell’idrogeno all’interno del composto di titanio possono provocare
l’allungamento del tempo di avvio con l’invecchiamento della pompa.
Durante l’esposizione all’aria, il deposito del composto di titanio
assorbe vapore acqueo; in conseguenza di ciò, al successivo avvio, il
riscaldamento della pompa provoca il rilascio del vapore e di parte
dell’idrogeno pompato precedentemente, con l’effetto
dell’allungamento del tempo di avvio.

Procedura per l’installazione
Procedure di uso
Procedure di uso
Controllare che la polarità dell’unità di controllo sia corretta per la
pompa: polarità positiva per le pompe Diode e negativa per le
StarCell e le Triode. Fare riferimento al relativo manuale ed
osservare la seguente procedura per l’uso della pompa:
1
Tramite una pompa di pre-vuoto portare il sistema da vuoto ad
una pressione minima di avvio in accordo alla tabella di pagina 9
ed a seconda del tipo di pompa ionica.
2
Collegare l’unità di controllo ad una apposita fonte di
alimentazione ed accenderla.
3
Osservare la tensione, la corrente e la pressione. Se l’avvio è
avvenuto ad una pressione di 5x10-2 Torr (mbar), è tipica una
tensione di circa 300 - 400 V. Un valore di corrente prossimo alla
corrente di corto circuito dell’unità di controllo è indice
dell’esistenza di una perdita nella pompa e nel sistema. Un
temporaneo incremento della pressione di pre-vuoto è normale
durante la fase di avvio.
4
Lasciare la valvola di pre-vuoto aperta durante l’avvio della
pompa ionica finchè non si raggiunge una adeguata pressione di
avvio. Se la tensione della pompa ionica scende dopo la chiusura
della valvola, riaprirla per un pre-pompaggio aggiuntivo. Appena
la pressione diminuisce, la tensione cresce nuovamente e la
valvola di pre-vuoto può essere chiusa.
5
Quando la tensione ha raggiunto i 2 - 3kV, mettere l’unità di
controllo nello stato PROTECT. Il sistema sarà così autoprotetto
dall’incremento della pressione oltre 1x10-4 Torr (mbar) quando
la pompa non è controllata. Nel caso in cui ci fosse un tale
incremento, l’unità di controllo viene spenta automaticamente.
6
La pressione nella pompa può anche essere calcolata leggendo la
corrente e convertendo la lettura in pressione tramite l’apposito
diagramma pressione-corrente illustrato nell’appendice
“Technical Information” di questo manuale.

Procedura per l’installazione
Procedure di uso
NOTA
I gradini nei diagrammi pressione - corrente sono una caratteristica del modo di
funzionamento del Dual. Quando la corrente assorbita dalla pompa raggiunge
determinati valori, l'unità di controllo cambia il valore dell'alta tensione in uscita
ad un valore più basso.
7
Quando si porta la pompa alla pressione atmosferica, usare azoto
secco in modo da evitare l’assorbimento di vapore acqueo da
parte delle pareti della pompa.
AVVERTENZA! Quando la pompa viene utilizzata per il pompaggio di gas tossici,
infiammabili o radioattivi, seguire le appropriate procedure tipiche di
ciascun gas. Non usare la pompa in presenza di gas esplosivi.
AVVERTENZA! Quando è installato il riscaldatore, non toccare la pompa durante le
operazioni di riscaldamento e di raffreddamento. L'elevata temperatura può
causare lesioni alle persone.
ATTENZIONE! Non avvicinare dispositivi elettronici alla pompa. Il campo magnetico attorno ad
essa può provocare dei malfunzionamenti dei dispositivi stessi.

Anleitung zur Installation
Gebrauch
Gebrauch
Sämtliche Hinweise für den korrekten Betrieb der Pumpen VacIon
Plus sind im Handbuch der Steuereinheit enthalten. Dieses
Handbuch ist vor der Inbetriebnahme genau durchzulesen. Es wird
empfohlen, die Pumpe auf einen Druck von 1x10-4 Torr (mbar) zu
bringen, um einen rascheren Anlauf zu gewährleisten. Zu diesem
Zweck empfiehlt es sich, keine ölversiegelte mechanische Pumpe zu
verwenden. Falls hingegen eine derartige Pumpe benutzt werden
muß, soll an der Vakuumleitung eine Falle eingesetzt werden, um den
durch die Wasser- und Öldämpfe aus der mechanischen Pumpe
erzeugten Druck zu verringern. Es ist zu versuchen, die Zeit auf ein
Mindestmaß zu reduzieren, während der die mechanische Pumpe
zum System und zur Ionenpumpe geöffnet ist, da sich ihre Dämpfe
bei Drücken unter 1x10-1 Torr (mbar) im System verbreiten und
dessen Verunreinigung verursachen. Bei Systemen, die vollkommen
ölfrei sein müssen, erweisen sich für den obengenannten Vorgang
Turbopumpen als geeigneter.
Hygroskopische Ablagerungen und die Absorption von Wasserstoff in
der Titanverbindung können die Anlaufzeit verlängern und eine
kürzere Standzeit der Pumpe verursachen. Die Ablagerungen der
Titanverbindungen absorbieren Wasserdampf, wenn sie der Luft
ausgesetzt werden. Dadurch bewirkt beim anschließenden
Anlaufvorgang die Aufheizung der Pumpe die Abgabe des Dampfes
und eines Teils des zuvor gepumpten Wasserstoffs, so daß sich die
Anlaufzeit verlängert.

Bedienungsschritte
2
Bedienungsschritte
Es ist zu kontrollieren, daß die Steuereinheit in bezug auf die Pumpe
richtig gepolt ist: positive Polarität für Dioden Pumpen und negative
für StarCell oder Triode Pumpen.
Es ist nach dem diesbezüglichen Handbuch vorzugehen, für den
Gebrauch der Pumpe sind die folgenden Bedienungsschritte zu
beachten:
1
Mit einer Vorvakuumpumpe das System auf einen
Mindestanlaufdruck gemäß Tabelle 9 in Abhängigkeit vom
Ionenpumpentyp bringen.
2
Die Steuereinheit an eine entsprechende Versorgungsquelle
anschließen und einschalten.
3
Die Spannung, die Stromstärke und den Druck beobachten. Wenn
der Anlauf bei einem Druck von 5x10-2 Torr (mbar) erfolgt ist, ist
eine Spannung von ca. 300 – 400 V typisch. Ein Stromwert, der
sich dem Kurzschlußstromwert der Steuereinheit annähert, weist
auf eine Leckstelle an der Pumpe und am System hin. Ein
zeitweiliger Anstieg des Vorvakuumdruckes ist während der
Anlaufphase normal.
4
Während des Anlaufes der Ionenpumpe soll das Vorvakuumventil
geöffnet bleiben, bis ein angemessener Anlaufdruck erreicht ist.
Wenn die Spannung der Ionenpumpe nach Schließung des
Ventils abfällt, ist das Ventil für eine zusätzliche
Vorvakuumpumpung zu öffnen. Sobald der Druck sinkt, steigt die
Spannung erneut an und kann das Vorvakuumventil geschlossen
werden.
5
Wenn die Spannung 2 – 3 kV erreicht hat, ist die Steuereinheit
auf den Status PROTECT zu schalten. Das System verfügt auf
diese Weise über einen Selbstschutz vor einem Druckanstieg über
1x10-4 Torr (mbar), wenn die Pumpe nicht kontrolliert ist. Falls
ein solcher Anstieg stattfindet, wird die Steuereinheit
automatisch ausgeschaltet.

HINWEIS
Der Pumpendruck kann auch berechnet werden, indem die
Stromstärke abgelesen wird und der abgelesene Wert mittels des
Druck-Stromstärke-Diagramms im Anhang “Technical
Information” des vorliegenden Handbuches in einen Druckwert
umgerechnet wird.
Die Stufen im Druck-Stromstärke-Diagramm sind charakteris-tisch für die
Funktionsweise des Dual. Wenn die Stromauf-nahme der Pumpe ein bestimmtes
Ausmaß erreicht, ändert die Steuereinheit die ausgangsseitige Hochspannung
auf einen niedrigeren Wert ab.
7
Wenn die Pumpe auf den atmosphärischen Druck gebracht wird,
ist trockener Stickstoff zu verwenden, um die Aufnahme von
Wasserdampf durch die Pumpenwände zu verhindern.
WARNUNG!
Wenn die Pumpe zur Förderung von giftigen, leicht entflammbaren oder
radioaktiven Gasen benutzt wird, sind die für das jeweilige Gas
vorgeschriebenen Vorgänge zu befolgen. Die Pumpe nie bei Vorhandensein
von explosivem Gas benutzen.
WARNUNG!
Wenn die Heizung installiert ist, darf die Pumpe während der Aufheizung und
Abkühlung nicht berührt werden. Die hohe Temperatur kann zu
Personenschäden führen.
VORSICHT!
Keine elektronischen Geräte in die Nähe der Pumpe bringen. Das darum
befindliche Magnetfeld kann zu Funktionsstörungen der Geräte führen.

Utilisation
Utilisation
Toutes les instructions pour le fonctionnement correct de la pompe
VacIon Plus sont fournies dans la notice de l'unité de contrôle. Il est
conseillé de lire attentivement cette notice avant d'utiliser la pompe.
Il est recommandé de porter la pompe à une pression de 1x10-4 Torrs
(mbars) de façon à obtenir un démarrage plus rapide. Pour ce faire il
est préférable de ne pas utiliser une pompe mécanique scellée à
l’huile mais au cas où il serait nécessaire d’utiliser une telle pompe, il
est recommandé d’introduire un dispositif de retenue le long de la
ligne de vide afin de réduire la pression due aux vapeurs d’eau et
d’huile engendrées par la pompe mécanique. Essayer de réduire au
minimum le temps où la pompe mécanique est ouverte vers le
système et vers la pompe ionique car ses vapeurs se répandent dans
le système à des pressions inférieures à 1x10-1 Torrs (mbars) causant
une contamination de celui-ci. Dans les systèmes où l’huile doit être
complètement absente, il est préférable d’effectuer ladite opération à
l’aide d’une pompe Turbo. Des dépôts hygroscopiques et l’absorption
d’hydrogène dans le composé de titane peuvent provoquer, par effet
du vieillissement de la pompe, l’allongement du temps de démarrage.
Pendant l’exposition à l’air, le dépôt du composé de titane absorbe de
la vapeur d’eau et cette action a pour conséquence qu’au démarrage
suivant le chauffage de la pompe entraînera la dispersion de la
vapeur et d’une partie de l’hydrogène pompée précédemment ce qui
aura pour effet d’allonger le temps de démarrage.

Procédure d’utilisation
Procédure d’utilisation
Contrôler que la polarité de l’unité de contrôle soit correcte pour la
pompe: polarité positive pour les pompes Diode et négative pour les
pompes StarCell et Triode. Se reporter au manuel correspondant et
observer la procédure suivante pour l’utilisation de la pompe:
1
A l'aide d'une pompe de pré-vide, porter le système à une
pression minimale de démarrage en suivant le tableau de la page
9 et en fonction du type de pompe ionique.
2
Brancher l’unité de contrôle à une source d’alimentation
appropriée et l’allumer.
3
Contrôler la tension, le courant et la pression. Lorsque la mise en
route est effectuée à une pression de 5x10-2 Torrs (mbars) la
tension est généralement d’environ 300 - 400 V. Une valeur de
courant proche du courant de court-circuit de l’unité de contrôle
révèle l’existence d’une fuite dans la pompe et dans le système.
Au cours de la phase de démarrage, un accroissement
momentané de la pression de pré-vide est normal.
4
Laisser la soupape de pré-vide ouverte pendant le démarrage de
la pompe ionique tant qu’une pression de démarrage appropriée
n’a pas été atteinte. Si la tension de la pompe ionique descend
après la fermeture de la soupape, la rouvrir pour un pré-pompage
supplémentaire. Dès que la pression commence à diminuer, la
tension augmente à nouveau et la valve de pré-vide peut être
fermée.
5
Lorsque la tension a atteint 2 - 3 kV, mettre l’unité de contrôle en
état de PROTECT. Le système sera ainsi protégé contre toute
augmentation de pression au-delà de 1x10-4 Torrs (mbars)
lorsque la pompe n’est pas contrôlée. Si une telle augmentation
devait être enregistrée, l’unité de contrôle s’éteindrait
automatiquement.
6
La pression de la pompe peut également être calculée en relevant
le courant et en convertissant la lecture en pression à l’aide du
diagramme pression-courant illustré dans l’appendice “Technical
Information” de ce manuel.

NOTE
Les paliers du diagramme de pression – courant sont une caractéristique du
mode de fonctionnement du Dual. Lorsque le courant absorbé par la pompe
atteint des valeurs déterminées, l'unité de contrôle porte la valeur de haute
tension en sortie à une valeur inférieure.
7
Lorsque l’on porte la pompe à la pression atmosphérique, utiliser
de l’azote sec de façon à éviter que les parois de la pompe
n’absorbent de la vapeur aqueuse.
AVERTISSEMENT! Lorsque la pompe est utilisée pour le pompage de gaz toxiques,
inflammables ou radioactifs, suivre les procédures appropriées à chaque
gaz. Ne pas utiliser la pompe en présence de gaz explosifs.
AVERTISSEMENT! Lorsque le réchauffeur est installé, éviter de toucher la pompe pendant les
opérations de chauffage et de refroidissement. La température élevée peut
provoquer des brûlures.
ATTENTION!
36/88
Ne pas approcher de dispositifs électroniques de la pompe. Le champ

Installation Procedure
Use
Use
All the instructions for the correct use of the VacIon Plus pumps are
contained in the control unit manual. Read the manual carefully
before using the pump. Rough pumping down to 1x10-4 Torr (mbar) is
recommended for the most rapid starting. Roughing with an oilsealed mechanical pump is not desirable, but when used, a trap in
the roughing line is recommended to reduce pressure due to water
vapor and oils from the mechanical pump. Be careful to minimize the
time that the mechanical pump is open to the system and ion pump,
since mechanical pump vapors will start diffusing into the system at
pressures below 1x10-1 Torr (mbar) and cause contamination. In
systems where oils must be completely eliminated, turbopump
roughing pumps should be used. Hygroscopic deposits and hydrogen
absorption into titanium may cause starting times to increase with
age. During exposure to air, the deposits of titanium compound
absorb water vapor. In subsequent start ups, pump heating causes
release of the water vapor and some previously pumped hydrogen;
thus, the starting time may be lengthened.

Installation Procedure
Operating Procedure
Operating Procedure
Check that the controller HV polarity is correct for the pump:
positive polarity for Diode pumps and negative for StarCell or Triode
pumps. Refer to the relevant pump control unit instruction manual
and follow the procedure below when operating the pump:
1
With a clean roughing pump, establish a minimum starting
pressure in the vacuum system per the table on page 9 for the
type of ion pump.
2
Plug the control unit into a suitable power source and switch the
power ON.
3
Observe the voltage, current, and roughing pressure. If started at
5x10-2 Torr (mbar), a controller voltage of approximately 300 to
400 volts is typical. A current value near the short-circuit current
of the control unit could indicate that an unconfined flow
discharge exists in the pump and system. A temporary rise in
roughing pressure will usually be noticed during any starting
procedure.
4
Allow the roughing valve to remain open after turning on the ion
pump until an adequate starting pressure is reached. If the ion
pump voltage drops after closing the roughing valves, reopen the
valve for additional rough pumping. As the pressure decreases,
the voltage again will rise, and the roughing valve may be closed.
5
When the voltage has increased to 2-3 kV, place the control unit
in the PROTECT condition. The system is now automatically
protected against pressure increases to 10-4 Torr (mbar) when the
pump is left unattended. If such an increase should occur, the
control unit will be turned off automatically.
6
The pressure in the pump can also be determined by reading the
current and converting this reading to pressure with the
appropriate pressure versus current graph shown in the
appendix “Technical Information” of this manual.

Installation Procedure
Operating Procedure
NOTE
The steps on the pressure – current charts are a characteristic of the Dual step
voltage operation. When the current drawn by the VacIon pump reaches the
specified values, the controller will change the high voltage output to a lower
applied voltage.
7
When venting the pump, use dry nitrogen. This will avoid water
vapor absorption on the pump walls.
WARNING!
When employing the pump for pumping toxic, flammable, or radioactive
gases, please follow the required procedures for each gas disposal. Do not
use the pump in the presence of explosive gases.
WARNING!
When the heating element is installed, do not touch the pump during the
heating and cooling phases. The high temperature may cause a serious
damage.
CAUTION!
Do not put any electronic device near the pump since the magnetic field may
cause a device malfunction.

Technical Information
Description of the VacIon Pump
Description of the VacIon Pump
The Agilent VacIon Plus 150 pumps are ion pumps and are available
in three types:
StarCell
Noble Diode
Diode
They operate in the pressure range from 10-2 to below 10-11 mbar.
Virtually all gases and vapors can be pumped successfully with the
ion pump. The pumping speed will vary depending on the system
pressure, the gas type, and the applied operating voltage. The latter
can be optimized using Agilent controllers to achieve the lowest
possible operating pressure.
The VacIon Plus StarCell pump allows starting from as high as 5x10-2
mbar, because ions are prevented from bombarding the system and
pump walls at starting pressures, and have high speed for inert gases.
The VacIon Plus Diode and Noble Diode pumps require a lower
starting pressure (i.e. 10-3 mbar).
The tantalum in the Noble Diode pump enhances the noble gas
pumping capacity, although it somewhat reduces the high getterable
gas pumping speed that the standard diode pump provides.
The VacIon Plus StarCell is the latest variation of the Triode
configuration. Its patented design makes this ion pump the only one
that can handle a high amount of Noble Gases (better than Noble
Diode and Triode) and Hydrogen (comparable to the Diode).
A positive polarity, high voltage supply is required to operate Diode
and Noble Diode pumps. A negative polarity high voltage supply is
required to operate StarCell pumps since the anode is grounded and
the cathode is held at negative potential.
The inlet ConFlat flange is a 6” (NW 100).

Technical Information
Technical Specification
Figures 5 to 12 show the pumping speed vs. pressure diagrams for
saturated and unsaturated pumps and the pressure vs. current
diagrams for the same pump. The diagrams are for pumps controlled
by means of a Dual controller.
The pumping speed of a newly regenerated (i.e. baked) sputter ion
pump decreases during operation until it reaches a stabilized level
known as "saturation" (nominal pumping speed). To saturate the
VacIon Plus 150 pumps, it normally requires an amount of gas equal
to 5 mbar-liters. Consequently, pumps can operate for extended
periods of time at low pressures in the non-saturated state, if they
are properly conditioned.

VacIon Plus Pump Installation
Inspection Procedure
VacIon Plus pumps are evacuated, baked out, sealed and leakchecked at below 1x10-10 mbar prior to shipping. The following
information and procedures can be used to evaluate the vacuum
integrity of a VacIon Plus pump before installation.
Visual Inspection
Inspect the pump and magnet for physical damage which may have
occurred during shipment. Inspect the pinch-off seal. If it is open, the
pump is at atmospheric pressure.
WARNING!
The pinch-off seal is extremely sharp. Be careful.
A VacIon Plus pump that has been exposed to atmosphere during
shipment, or while in storage, will operate properly if it has not been
damaged.
The pump is not harmed by such exposure, although it is good
practice to keep it under vacuum when not in use to exclude dust
and the accumulation of water vapor from the environment.

Technical Information
VacIon Plus Pump Installation
Vacuum Evaluation
The ion pump is shipped in an evacuated condition. Before removing
the shipping flange for installation on a vacuum system, it is
recommended that the pump be started briefly to verify vacuum
integrity and proper operation.
To verify the vacuum integrity of the new pump before venting:
1
WARNING!
Connect the pump to the control unit as directed in the
instruction manual of the control unit.
The high voltage which is present in the ion pump from the control unit can
cause severe injury or death. Be sure that the high voltage cable is proper
connected to the ion pump and its power unit. Make sure that the pump is
well grounded.
2
With the main power switch in the OFF position, plug the control
unit into a suitable power source.
3
Turn the power to ON.
4
Observe the reading for an indication of one of the following
conditions:
5
a
If the pump is free of leaks and is at a low pressure, the
pressure indication shall quickly fall to or below the
10-8 mbar range as the volume of gas is pumped.
b
If the pressure inside the pump is at or near atmospheric
level, an arc may strike inside the high voltage feedthrough
giving a popping sound and the pump current will fluctuate.
If this occurs, turn the power OFF immediately.
If the vacuum integrity has been lost, the pump should be leakchecked with a mass spectrometer leak detector before
installation on the system.

VacIon Plus Pump Installation
Short Circuits
If there is a short circuit between the anode and cathodes in the
pump (or cathode to pump body), the short-circuit current of the
control unit will be drawn and low voltage will be indicated. If a
short circuit exists in the control unit or high voltage cable and
connector, low voltage will also be observed when the high voltage
connector is disconnected from the pump (refer to the control unit
manuals).
An ohm meter reading on the pump feedthrough may not be effective
in finding a short.
Short circuits may be caused by mechanical shock to the pump. If the
pump is shorted, contact Agilent.

Inlet Flange Connection
Inlet Flange Connection
The pump should be mounted allowing a sufficient clearance for
installation and removal of the high voltage connector.
The pump should be kept sealed with its pinch-off tubulation until it
is ready for attachment to the vacuum system. This avoids
accumulation of dust and other undesirable materials. Before
breaking the pinch-off seal, consult the inspection procedure (see
preceding paragraph).
Vent the ion pump by opening the pinch-off tubulation in a clean area
free from smog, dust, pollen, etc. Venting with dry nitrogen gas is
further recommended. This can be done by placing a clean
polyethylene bag over the ion pump flange. Small pumps can be
placed inside of the bag. Purge the bag with clean, dry nitrogen for
several minutes, then reach into the bag and release the internal
vacuum using pliers to open the copper tube pinch-off.
CAUTION!
Do not open the pinch off-seal with a saw or grinder. These methods will cause
metal particles to be drawn into the pump by the inrushing air as the pump is
opened.
WARNING!
The pinch-off seal is extremely sharp. Be careful when opening. Watch your
fingers.
Use appropriate procedures to maintain the clean condition of the
pump and vacuum system.
Unscrew the main flange bolts and lift the blank flange with the help
of a bolt screwed into the available threaded hole. Remove the
ConFlat flange and the copper gasket plate. Some particles of copper
oxide may adhere to the outer edge of the flange gasket. Be careful
not to allow them or any other foreign materials to fall into the pump.

Technical Information
Inlet Flange Connection
Connect the ion pump to the vacuum chamber with a short length
and large diameter tubulation in order to retain as much pumping
speed as possible. Proceed as follows:
NOTE
1
Inspect the mating flanges for cleanliness and absence of
scratches on the knife edge.
2
Place a new copper gasket between pump flange and vacuum
chamber flange.
3
Bolt mating flanges of the pump to the chamber with the screws
provided with the ion pump. For flanges over NW 35 (2.75" o.d.)
also mount washers below the nuts and screw heads.
4
Use silver-plated screws or apply high temperature lubricant to
the screw threads. Lubrication simplifies sealing and
disassembly. A recommended lubricant is Fel-Pro C-100.
Lubrication is essential to prevent galling of the nut and screw after bakeout.
5
Attach the nuts and tighten each one to 6 – 11 Nm (4.5 - 8 ft.-lbs)
of torque. After tightening a nut, always tighten the opposite nut
with respect to the center of the flange. This will partially close
the gap between the flange faces.
6
Repeat the sequential tightening for two more cycles.
7
Continue tightening the bolts until the flange faces meet and a
pronounced increase in torque is felt.
Note that it’s not possible to install the screws from the lower side,
but only from the upper side of the flange. To allow complete
flexibility in the installation, a stud mounting kit is available (see Fig.
22). For ordering information refer to the “VacIon Plus pump
replacement parts and accessories” paragraph.

WARNING!
The high voltage present in the high voltage cable which connects the control
unit to the ion pump, can cause severe injury or death. Before mounting the
high voltage connector of the cable on the pump high voltage feedthrough, or
before removing it, be sure the main power is removed from the control unit.
WARNING!
To avoid injury, never connect the high voltage to the pump before it is
installed into the system and all the inlet flanges are properly connected or
blanked off. Make sure that the pump is well connected to the grounded
vacuum system.
WARNING!
Before removing the high voltage connector of the cable from the control unit,
be sure the main power is removed from the control unit. Wait at least 10
seconds after removing the main power from the control unit, to allow
capacitors to discharge completely.
To disconnect the coaxial high voltage cable from the controller, slide
the safety locking sleeve (very little sleeve travel is required) from the
control unit and at the same time pull on the male end of the cable
connector to remove it from the socket on the control unit.

Bakeout Operation
When a VacIon pump does not reach the desired base pressure, and
there are no leaks, it is necessary to bake the system. This is done by
heating the pump and all the components in the system, and is
generally required to achieve base pressure less than 10-8 mbar.
72/88
1
Heat the pump body and the system with a bakeout oven unit or
heating strips to temperatures between 150 °C and 220 °C (220
°C is the maximum allowable for most bakeable high voltage
cables). This temperature is high enough to degas the pump
surfaces of water vapor without damaging the magnet and high
voltage connector. Note that the system components must be
compatible with the bakeout temperature. The heating must be
approximately even on all surfaces or evaporated water will
condence on the colder surfaces resulting in an incomplete bake
and preventing achievement of UHV vacuum pressure.
2
Leave the pump control unit on and monitor the pressure.
Agilent recommends that current during bake not exceed 25 mA;
if this value is exceeded, turn the bakeout off and then on again
when low pressure is restored. To control the heaters and to
monitor the high pressure limit during bakeout in automatic
mode, an automatically controlled relay may be used.

Technical Information
Bakeout Operation
3
Bake the VacIon Plus pump for at least 24 hours. Longer bakeout
periods are recommended when the pump has been used with
heavy gas loads or when UHV pressure, 10-9 mbar or less is
desired.
4
As the pump and system cool down to room temperature, a drop
in pressure should be observed.
Note that the ion pump can be also baked when switched off, into an
external turbo pump through a bakeable isolation valve.
Bakeout of VacIon Pump with the Integral Heaters
NOTE
WARNING!
1
The integral heaters are to be powered with the appropriate
voltage. (Please refer to the inscription on the heaters to apply
correct voltage).
2
The integral heaters are designed to provide a temperature of
250 °C to 300 °C when the pump is wrapped in a 3-fold
aluminium foil.
A three-layer foil wrapping is advisable and sufficient to achieve full
bakeout/regeneration if the standard European heaters (230 Vac) are operated
at 240 Vac, thus preventing overheating.
3
Bakeout the VacIon pump for 24 hours. If the pump is used in
heavy gas load applications, it is recommended to bakeout the
pump for a longer period.
4
Wait until the pump cools down to room temperature and
recovers its base pressure before using it in the application.
Do not touch the pump during the heating and cooling phases. The high
temperature may cause serious damage.

Operating Procedure
Operating Procedure
1
Using a clean roughing pump, evacuate the system to a minimum
starting pressure as stated by the technical specification. 10-6
mbar or less is recommended. To reach this pressure the use of
an oil free turbo-molecular roughing pump is recommended.
2 When starting an ion pump, a slight increase in vacuum pressure
is normal as the internal components are heated and outgassed.
If possible leave the roughing pump connected to the system
while starting the ion pump. This will make the startup faster
and easier.
3 Connect the control unit to a suitable power source and switch
the power on.
4 Switch on high voltage to the pump and observe the current and
voltage. Fastest starting is obtained using a high applied voltage,
7 kilovolts for example. The applied voltage may be reduced later
to optimize pumping and achieve the lowest vacuum pressure.
5 If started at 10-4 mbar, the voltage will start at approximately
800 volts and increase to full voltage as the pump starts
operating. The current will start at several milliamps and slowly
decrease to microamps or nanoamps as low vacuum pressure is
achieved.
6 When first starting the pump, if the voltage decreases instead of
increasing, reduce the vacuum pressure then start the ion pump
again.
7 When the pump reaches its full operating voltage, you may close
the roughing valve.
8 If the pump does not start after 30 minutes of pumping, see the
section PUMP TROUBLESHOOTING.
9 Once the pump reaches its base pressure with stable voltage and
current, the ion pump may be baked at high temperature if
required per the section titled BAKEOUT OPERATION.
10 To stop the ion pump, simply switch off the high voltage. The
pump surfaces will continue to pump for a few minutes
depending on the system pressure.
11 When venting the pump use clean, dry nitrogen. This will avoid
water absorption on the pump surfaces and make subsequent
pump downs easier.

Leakage Current Check
If the pump current reading is to be used as pressure measurement,
check the pump leakage currents as follows:
1
Turn off the pump control unit.
2
Remove the pump magnet.
3
Turn on the pump control unit and wait for current stabilization.
The current reading should not be higher than 150 nA. Make sure
that the control unit and the high voltage cable leakage current is
negligible.
4
If leakage current comes from the pump, perform "high-potting"
per the following procedure; then recheck the pump and install
the magnet.
5
If it is not possible to "high-pot" the pump, the pressure reading is
biased by the leakage current value.

Technical Information
Maintenance
High-potting
A constant pump current when no vacuum leak exists is often caused
by field emission currents which prevent the use of the pump current
as a UHV pressure indicator. To reduce this field emission current,
"high-potting" should be performed. "High-potting" is the term used to
describe the application of higher than normal operating voltage
(8 kV AC, max. 50 mA) for the purpose of burning off "whiskers"
(sharp edges) on the pump cathode.
High-potting should be done under vacuum and preferably without
pump magnets installed (to reduce the drawn current).
High-potting must be done carefully and in voltage steps since
uncontrolled arcing inside the pump can cause permanent damage.
Therefore slowly increase the applied voltage and watch the current
meter for indication of arcing inside the pump as whiskers are
burned away. If arcing occurs wait at this voltage until the current is
stable again. Then slowly increase voltage again in steps up to a
maximum voltage. The maximum voltage may be applied to the pump
for a period of about 15 seconds. This should effectively remove any
"whiskers" or sharp edges on the pump cathode.
WARNING!

Voltages developed in the High Potter power sup-ply are potentially lethal.

Symptom
Possible cause
Correction procedure
1) – Slow starting
Starting vacuum pressure too high.
Reduce pressure to 10-5 mbar
recommended 10-4 mbar
minimum.
2) – Slow starting
(more than 30 minutes).
Air leaks which limit pressure to above 10-6
mbar and cause longer starting time.
Leak check the vacuum system
with a helium leak detector.
3) – Slow pump-down
due to long exposure of
viton parts to air.
Viton releases considerable gas after long
exposure to air. (A bell-jar system which
reached 2 x 10-8 mbar in 24 hours after 30
minutes air exposure, will only reach 1 x 10-7
mbar in 24 hours after 20 hours air exposure)
With the system under vacuum,
pump for several days, or heat
to 100-150 °C for up to 15
hours.
4) – Slow pump-down
due to absorption of
vapours on pump and
system walls.
Vapours and gases admitted to a system are
absorbed on the walls of the system and
pump. Subsequent reduction in pressure
depends on the rate of depletion of this
vapour. Heavy hydrocarbons are most
troublesome because of their relative low
vapour pressure and they are very difficult to
remove, even by baking.
Bake the system walls, thereby
accelerating the desorption
process. Baking mobilizes the
vapours so they can be cracked
and pumped by discharge (see
section “BAKEOUT
OPERATION”).
5) – Slow starting or
slow pump-down.
High voltage feedthrough is leaking.
Replace the feedthrough.
6) – Current higher than
expected at any given
pressure.
Ion pump leakage current causing higher
pressure reading.
Highpot the pump.
7) – System fails to
achieve desired UHV
vacuum pressure.
System not fully baked. Water vapor limits
base pressure.
Bake the system walls, thereby
accelerating the desorption
process. Baking mobilizes the
vapours so they can be cracked
and pumped by discharge (see
section “BAKEOUT
OPERATION”).
8) – System fails to
achieve desired UHV
vacuum pressure.
System not appropriately cleaned for UHV.
Excessive outgassing from walls limits base
pressure.
Clean all components for UHV
and bake the system again.
