    keyword=Rate discrepancy

    Did the DAQ switchover checklist to go to counting mode.
    First problem : rates are very imbalanced

    Left HRS
    T1 = HAPPEX trig = 3240 Hz
    T2 = S0 trig = 3220 Hz

    Right HRS
    T1 = HAPPEX trig = 700 Hz
    T2 = S0 trig = 720 Hz

    But the beam current is drifting up too.
    R-HRS HAPPEX det went up to 1800 V temporarily.
    Saw a 20 Hz change.
    Went back 1600 V.
