Transfer rod with marked positions 

1- Sample transfer.

• Mount sample in transfer rod

• Push transfer rod until first position (roughing pump stage). Wait 5 minutes. Pirani reading is not too reliable

• Push transfer rod until second position (turbo pump stage). Leave there between 30min and 2hours (more if it is a powder sample). The gauge is broken

• Push transfer rod to last position (inside XPS chamber). Wait until pressure drops below 10^-7 Torr. Set gauge in 10^-7 Torr range before turning on XPS (there is a pressure interlock)

• Check that teflon piece at the end of rod is not protruding out.

2- Turn on system 

Main interlock box   

• Press the main interlock button (green).

• Turn on X-ray source (turn on Water On, HV On)

• Increase slowly HV (big knob) to 6kV

• Switch from stanby to operate (small switch knob in upper module)

• Increase slowly HV to 13kV

• Turn on analyzer electronics (5 VG white modules on the left rack)

• Turn on the channeltrons voltage (switch in lowest VG module)

• Adjust ratemeter. In test, if meter is not in the middle of the range, press increment button and then press up or down switch to move needle left or right.

• Check USB module is on (both connected to PC and to power, green light on)

•  Run program

3- Turn off instrument:

• Turn of channeltron voltage

• Turn off analyzer electronics (VG)

• Lower X-ray gun from 13kV to 6kV

• Turn knob to standby mode in x-ray gun upper module

• Lower x-ray gun to 0kV

• Turn off x-ray gun electronics

• Turn off main interlock (press red button).
