13:06~13:16 #25927,#5464 2uA, VDC on, FADC off
13:16~13:30 #25928,#5465 2uA, tune PS to be more reasonable
Ramping down VDC HV for high current
13:40~13:42 #25929,#5466 Once I start the run, I realized I didn't download the crl code with FADC on. Download it.
13:45~13:54 #25930,#5467 MCC cannot provide stable 100uA beam, and we go to 90 uA instead. Beam trips often in this run. (details of PS setting is the same as below)
13:54~14:10 #25931,#5468 90uA, high T1 taking rate run (low PS on T1=2500, high PS on GC 25000). The T1 rate after PS is 100HZ, GC rate is 10HZ, and the current deadtime is 30%, which is the current optimal setup of date taking with the consideration of raw data loss due to both PS and DT loss. 120K events recorded.
14:10~14:52 #25932 change both PS(T1) and PS(GC) to be 5000 so that both T1 and GC are 50HZ after PS, while deadtime is still 30%. 300K events recorded.
Run end by 14:52.
