    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
