beam: 205Tl81+ (no scraping , Al ~1g/cm2)
energy: 400 MeV/u
storage time: 5 hr
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 22:11, run0308.lmd
file running: 0313.lmd
_______________________________________________________________________________
time when accumulation starts: 09:47
time when storage starts: 10:19
time when storage ends: 15:19
I_cooler during storage time: -1 mA
I_cooler = 177 mA
I_SIS: 1.75e9
ESR particles after stacking: 2e6 (offset 5e5)
Number of stackings: ~70 (was set to 80 but we missed few shots)
