beam: 205Tl81+ (no scraping , Al ~1g/cm2)
energy: 400 MeV/u
storage time: 8 hr
S2: 0/35 mm
purpose: data with TARGET ON
Detector position (CsISiPHOS): out of the ring
Detector position (MWPC): -60 mm
run start at 11:17, run0303.lmd
file running: 0306.lmd
_______________________________________________________________________________
time when accumulation starts: 13:32
time when storage starts: 13:51
time when storage ends: 21:51
I_cooler during storage time: -1 mA
I_cooler = 179 mA
I_SIS: 2e9
ESR particles after stacking: 3e6 (offset 0)
Number of stackings: 50
Target ON density: 3.95e12
Target on time for measurement: 10 mins (by event mode)
time spend at manipulation 13 : 5 mins
(i.e. time for which electron cooler is on after gas jet)
at 18:30 (start was at 13:51) the stored particles: I_ESR = 1.7e6
at 19:00 the stored particles: I_ESR = 1.6e6
at 19:30 the stored particles: I_ESR = 1.48e6
at 20:00 the stored particles: I_ESR = 1.5e6
at 20:30 the stored particles: I_ESR = 1.4e6
at 21:00 the stored particles: I_ESR = 1.34e6
at 21:30 the stored particles: I_ESR = 1.34e6
