00:00 Status at start of shift:
Tune Y counting mode 0.5 uA on superthin target
Tune X for Left arm
Tube B for both arms
01:45 Control access to put AT detector to integrating mode (Parity DAQ)
02:10 Control access completed. Move the target to EMPTY
02:10 Both arms has HV for VDC OFF, S0 OFF, Upper and Lower scint OFF , Lumi is ON
02:30 Beam is 5 uA, positions OK, mode 240 Hz, reporting delay 16
02:45 Beam is 5 uA, raster size is 4x4 however position is shifted up 3 mm, move to BeO
02:55 Beam is 10 uA, some light is observed when laser ON/OFF
03:05 Target BeO, Beam is 10 nA = att. 65 slit 17
03:15 Left arm HV upper scin. T5, rate is 25,000 Hz
Investigation why the rate is high, Rate vs raster current is OK.
Use att. 55 so rate is 1.5 kHz
03:45 Move to Lead#3 target, asked 3 uA
A_T scan
05:50 Q1 trip, He level recovery take long
06:50 Q1 recover, John continue A_T scan
