S2: 0/35 mm
s6: -20/7
purpose: data with TARGET ON
Detector position (CsISiPHOS): out of the ring
Detector position (MWPC): -60 mm
run start at 20:21, run0540.lmd
file running: 0546.lmd
_______________________________________________________________________________
time when accumulation starts: 21:43
time when storage starts: 22:21
time when storage ends: 22:51
I_cooler during storage time: -1 mA
I_cooler = 179 mA (20 mA)
I_SIS: 1.75e9
ESR particles after stacking: 2.2e6 (offset 3e5)
Number of stackings: ~90 (was set to 100 but ~10 were missed)
