▪
The high voltage cable is attached to the controller and the ion pump.
▪
The controller’s high voltage output has the correct output polarity for the
ion pump (positive voltage for diode pump and negative voltage for triode
pump).
Evacuate the vacuum system
1.
Rough pump down to 1x10-4 Torr or less (the lower the better). See
Rough Pump manual for details.
2.
Ensure contaminants do not exist in the system.
3.
If an ion pump is used or has been exposed to atmospheric pressure, it
may be necessary to bake the pump into the roughing pump to achieve
the best pressure. See the Operation section in the Pump manual for
details.
Starting the ion pump
1.
If the ion pump size has not been entered into the System Menu, enter
the ion pump size. The SPCe will not start until the ion pump size has
been entered.
2.
Press and hold High Voltage on the front panel for 1-2 seconds.
Stopping the ion pump
Press High Voltage on the front panel to disable high voltage.
