TRANSFER&EVAPORATION Positions

Normal photon beam incidence: 178.5 degree. Normal electron emission: 238.5 degree. Normal photon emission: 118.5 degree. 

TRANSFER x y z theta NOTES
           
  28 20 24.9 (1.0) 180 RT
           
IMPORTANT: Before rotating and during the rotation, always watch and monitor the sample holder through the CF40 window on top of the chamber. Also look at the monitor with the camera (camera 3) watching the LEED. There is high risk of hitting the MCP or the analyser or the LEED!!

IMPORTANT: In order to switch off the Omicron evaporators:
1. Turn HV to min
2. Turn I to 0 A
3. Set the controller to STAND BY (IMPORTANT!!!!)
4. Wait for 30 minutes then close water (fist close IN then close OUT)

BEFORE LEED: Always turn on the Camera 3 before rotating the sample in front of the LEED. Do not rotate for y>25!

IMPORTANT:BEFORE SPUTTERING! Close the last beamline Valve and Switch off the XPS before introducing Ar in the chamber.
Ar pressure=1.2 x10-6 mbar. Do not sputter more than 15 minutes.
