keyword=PITA scan and PITA feedback
I took the chance to measure the PITA slope while Hall C was off (it turned out that Hall B was also off for this). This is the first measurement of the PITA slope since the cathode spot move this morning. IHWP was in and RHWP = 6500.
Run 2445 - junk (forgot to turn feedback off before starting)
Run 2446 - PITA scan, IHWP IN, RHWP = 6500
Run 2447 - production (feedback on again)
The PITA slope was measured to be 9.94 ppm/V or 596.4 ppm/DAC V.
The charge asymmetry offset was -276.06 ppm.
During run 2447, PITA feedback was done between events 9k and 10k. The new PC voltages are: POS = 3.775
NEG = 6.814
Just a reminder that Hall C (and B) were off. Our IA is sitting nicely around 5 V right now.
