keyword=spectr. DAQ runsBeam 0.2 uA (actually see 0.28 on EPICS).
LH2 target in.
Switched to spectrometer DAQ. Did the checklist.
Rates:
T1 = 195 kHz
T2 = 145 kHz
T3 = 192 kHz
T4 = 128 kHz
T5 = T6 = 0
T7 = 259 kHz
T8 = 243 kHz
Spectrometer run 2814.
P_L = 3.128, P_R = 3.127 nominally correct.
All HAPPEX detector 1900 V.
Problem: One of the HAPPEX detectors is missing. It appears
in neither ADC nor TDC nor scaler.
The detector map db_P.dat says it should be in the
3rd descriminator input, which is consistent with halog 156639
but it looks like it is not plugged in.
Meanwhile we put momentum to -2% to start checking alignment but
we'll need to take access to fix the above, before going too far.
