EPICS overview - change the dates to suit
Shift leader instructions & desperate logbook entry on prestarts
wish list Remaining items are EPICS gathering (Thomas) & move to Prestart (David in Jan, or ask Sergey)
The default GCF in CCDB for runs 120,000+ is 0.1491. This is good.
Summer 2020 runs 72075 and 72766 started at close to 350nA and w pressure close to (and on either side of) 100kPa, have GCFs 0.148 and 0.150.
Run starts Jan 12
Naomi out Jan 3-23.
Initialization?
source $HOSS_VENV/bin/activate.csh python3 /group/halld/AIEC/AIEC_CDC.py -c /group/halld/AIEC/AIEC_CDC.cfg -I 15
Jan 12 RoboCDC control off, because the pressure sensor was not working reliably for most of January. Jan 24 logbook entry describing pressure sensor issues
Feb 16 120739-120745 RoboCDC control on. According to EPICS, the AI switch was on from 121718, but the HV was fixed at 2125V until 120739.
Feb 20 120746-120750 10am - 3pm RoboCDC control switched off for the duration of MCC's BCM recalibration (which was found to be unnecessary)
Feb 20 120751-120821 RoboCDC control on. Feb 23 4pm ish Changed the current input to fixed because it was causing so many badepics
Feb 24 120822-120830 switched the control off because the script was running so late and setting the HV after the run started.
Feb 25 120831-120832 Control switched back on for two runs and then off again afterwards.
Feb 25 120833-120920 control off
Mar 1 120921-120931 Late evening control switched back on, HV set to 2123V during tests, script failed and HV remained at 2123 overnight.
Mar 2 120932 10:30am HV set back to 2125V manually. Control still on. Beam off.
Mar 2 120933-121007 Resumed operation correctly later that day (there was a long beam outage).
Mar 6 121008-121009 Control switched off for high current tests.
Mar 6 121010-121022 Control switched on when maintenance day was announced instead.
Mar 7 121023-121025 Control switched off during high current tests.
Mar 7 121026-121035 Control on
Mar 8 121036-121042 Control switched off during high current tests.
Mar 8 121043-121106 Control on
Mar 10 121076-121105 HV remained at 2121V, looks suspicious.
Mar 12 121106-121121 HV returned to 2125V
Mar 13 121122-121147 Looks like control was on again
Mar 15 121148-121155 Control off for high current tests
Mar 16 121156-121214 Control on
