keyword=OWL Shift Summary
00:00 IHWP -> OUT; resume production running with Run 2416
01:00 Profile scan, full area -- run 2418 (2417 brief; wrong voltages
on profile detectors). Scanner potentiometers had readout
problems, so we decide to defer profile scan at half operating
01:19 Resume production running
02:10 Noticed Hall A IA loop was railing though charge asym still
zero. Culprit was recent turn-on of Hall C beam (to 50uA).
02:15 MCC called to say Hall A laser power is maxed out giving us 32uA
because Hall C is getting 50uA (and draining cathode?). With
cathode lifetime short, we see current dropping steadily through
remainder of shift.
03:28 Raised lumi voltages to bring lumi signals up to ~40k at 30uA
04:30 Inserted IHWP and updated RHWP, Pockels cell voltages, and Hall
C IA voltages.
05:00 Target IOC reboot.
07:30 Noticed Left Septum He level had been dropping steadily for last ~2hrs. Was at 51% when we caught it. Called RC and then Tech on call. Going into controlled access to reset He reservoir JT valve.
HAPPEX DAQ run summary
2416 production; removed IHWP prior to start. IHWP OUT
2417 profile scan; aborted after 3900 events (wrong prof det HV)
2418 profile scan, full area.
2419 production IHWP OUT
2420 production IHWP OUT
2421 production? raising LUMI voltages during run but otherwise
2422 production IHWP OUT
2423 production; inserted IHWP prior to start. IHWP IN
2424 production IHWP IN
2425 production IHWP IN; PITA fdbk at 45k events
2426 production IHWP IN
Compton DAQ run summary
8516 IHWP OUT ~00:00 - 02:10
8517 IHWP OUT 02:16 - 04:20 forgot to start left-right process and
when "end run" failed I never got an end-of-run window.
8518 IHWP IN 04:25 - 06:25 forgot to start left-right process
8519 junk due to DAQ problem(?) -- after hitting "start run",
window that opened crashed.
8520 IHWP IN 06:55 - started left-right process.
