keyword=start beam quality checks
We are going to beam quality checks : set up for superharp scans
- ask for coil modulation off
- ask for fastfeedback on
- ask for 20 µA
- set BPMG0, BPMG0B back to Auto gain
- beam had shifted by 1 mm; CAEN sniper tripped HVoltages. Turn them
on again, but they trip within a few minutes...
decide to leave detectors off for beam quality checks
