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
Check 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.

Water flow and Temperature
FLOW/TARGET 9.6
FLOW2TUBE 4.3-4.2

CRYOSTREAM

Let if warm up first
PROGRAM/ turn black knob: "Add Phase: End"
ENTER twice / HOLD (green light come OFF)

2h to cool up
1h-30 min to cool down

BEAM 

Point detector         every week
Check beam intensity
Slide on the collimator and tighten

SCALE: 3   DIVISION: 2
ON   ADJUST ZERO with dial

on XG Control: Shutter / OPEN     read > 4,  never above 5.0
