Half hour measurement (S2: 0/35 mm) |
|
|
beam: 205Tl81+ (no scraping , Al ~1g/cm2)
energy: 400 MeV/u
storage time: 0.5 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: 0303.lmd
_______________________________________________________________________________
time when accumulation starts: 11:19
time when storage starts: 11:46
time when storage ends: 12:16
I_cooler during storage time: -1 mA
I_cooler = 177 mA
I_SIS: 2e9
ESR particles after stacking: 3.2e6 (offset 5e5)
Number of stackings: 54 (was set for 60 but we missed a few)
Target ON density: 3.66e12
Target on time for measurement: 10 mins (by event mode)
time spend at manipulation 13 : 23 mins (as Shahab wanted to record data with 400 MHz schottky)
(i.e. time for which electron cooler is on after gas jet)
NTCAp file:
SC_2020-04-03_11-20-14
\IQ_2020-04-03_11-20-05
IQ rate: 8 MS/s
(saved in drive : p)
copy and repeat the above (below the line) for every storage time measurement |
