AIDA run with Takechi experiment. 71~73 Ni beam setting
F5 carbon target is: IN
F7 CH2 target is: OUT
F11 carbon target is: OUT
All variable Al degraders at F11 are OUT
When the run started, we had 1mm Al degrader in (count rate of AIDA was near the background rate)
Then we took out the final 1mm Al degrader, and we started to get counts on AIDA (600 Hz on detectors 1, 2, 3, very little on 4, 5, 6)
Run file: NP1412/R1
ASIC parameter file: 2016Nov07-23.03.06
5 mm thick Al stopper is at the center of BRIKEN, with AIDA slightly behind it
Run start: 8/11/2016 22:00
Leak currents (4 to 5 uA each) shown as Attachment #1
