Maintenance
XG Control (radioactivity icon)
Control: 45 kV and 66 mA (20 kV and 10 mA in idle status)
Raise the voltage first.
Lower the intensity first.
- 66 → 60; steps of 10 (15-20 s for each step)
- 45 → 40; steps of 10 (idem)
(It takes a couple of minutes in total)
Scripts: Aging/Start script to restart Short takes 31 min. After that you should wait 1-2h for a stable beam
No need to shut down if it's for less than a week
To shut down, first go to idle status (20 kV, 10 mA), then X-rays OFF, and stop vacuum after Chekc if Chiller/Target are also off after in the Main
For RESTART
- CHILLER
- PUMP(VACUUM)
- X-RAYS
[7.6E-5 (Pa) Vacuum level] [140 Bias] electronic force applied on the beam Don't change the filament current FC 6.6 V Change the bias for each new filament to reach the FC of 6.6 V
When it has just restarted: Stay in idle (20 kV, 10 mA) overnight if it was down for several weeks; only 1-2h if it was down a few hours.
