**********running without the Left arm******************
Left Q1 turned on, for good lumi signals
00:00 test run # 13582. just got the target parameters set up for production run. checking the lumi/det widths.
00:30 noticed that the RHWP is @ 10, used to be 1200.
00:50 Dusting getting ready for Q2 measurement. ask MCCfor 1 uA
1:04 ask MCC for 5 uA
1:10 ask MCC for 10 uA
1:20 Dustin is done with the Q2 measurement. ~ 0.62 (preliminary results). ask MCC for 100 uA
1:46 lumi/ right arm det HV adjusted to get enough signal on the 18 bit adcs
1:46 turned the charge feedback off, since the RHWP position was off, and the charge feedback pegged the PC voltage and hall C IA voltage
1:45 compton running fine now. Diancheng worked with MCC to get the compton stable @ 100 uA. we have not been able to run compton @ 100 uA before.
2:30 RHWP @ 1200, charge asym & hall C IA feedback on
3:24 just realized that the magnets was set @ MODULATION OFF. should have been on ON for dithering to work. dithering was turned on at 3:30 am, starting run # 13586
5:49 compton HV trip (twice in a row)
8:00 production run underway
run # 13582: test run, check lumi/det widths.
run # 13583: test run, adjust the lumi/det HV for, PC/hall C IA voltage pegged, charge feedback turned off.
run # 13584: started at PC/hall C IA pegged, but adjusted the voltages.
run # 13585: production @ 97 uA, RHWP @ 1200, feedback on, dithering off on MCC's end
run # 13586: production @ 96 uA, dithering back on
run # 13587: production @ 96 uA
run # 13588: production @ 96 uA
run # 13589: production @ 96 uA
run # 13590: CODA error, no data
run # 13591: production @ 97 uA
