Failed measurement...Ten hour measurement (S2: 0/35 mm and S6: -20/7 mm) |
|
|
FAILED - measurement was stopped by sudden loss of the beam
beam: 205Tl81+ (no scraping , Al ~1g/cm2)
energy: 400 MeV/u
storage time: 10 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 19:02, run0343.lmd
file running: 0347.lmd
_______________________________________________________________________________
time when accumulation starts: 19:17
time when storage starts: 19:55
time when storage ends: 05:55
I_cooler during storage time: -1 mA
I_cooler = 177 mA
I_SIS: 1.8e9
ESR particles after stacking: 2.5e6 (offset 3e5)
Number of stackings: 100
Target ON density: xxe12
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)
I_ESR (20:30) : 2.25e6
I_ESR (21:00) : 2.1e6
I_ESR (21:30) : 2.0e6
