MAMI needs optimization
Beam off → ELOG entry “beam off, MAMI optimization, maybe reason”
Detector HV off and afterwards pre-HV off (
How to ramp the high voltage
)
Change target to “Empty” (
Target control
)
Now MAMI can start the optimization → call MAMI
when the optimization is finished, normally <1h (call from MAMI): check beam position (
Target control
)
change target to luminescent screen (Al203)
turn on target camera
turn on beam slowly (MAMI) until you see a white spot
ask MAMI to center the beam
take a picture
turn beam off
now you can move to the desired target (
Target control
)
turn HV back on (
How to ramp the high voltage
)
turn beam on with the desired current → ELOG entry “beam on, target XY, current XY”
