  21   Mon Apr 5 16:07:36 2021 RobertRunsHe-like run
run started thursday 21/04/01 20:00,
ended monday 21/04/05 15:20, 
time span of 91.5 h,
we collected 4870 images with a esr cycle of ~62s, 
thats ~84 h of accumulation,
20 s gas jet on time, so we integrated 27,1 h of gas jet on

particle density was 2.25*10^12 particles /cm² at the beginning and increased continuously to 3.1*10^12 particles/cm²

ion beam intensity was between 4-5*10^7 stored, cooled particles per injection
  23   Tue Apr 6 14:47:26 2021 RobertAnalysisstability of the spectrometers during He and Be run
the large spike in the outer spectrometer is attributed to an open door of experimentierhalle, which we closed at ~17:00 at 21/04/05.
It might be necessary to exclude some of the data between 210405 17:00 and 22:00 since we had a shift of one pixel between these two calibrations

run started 210405 17:50
run ended 210407 11:30
no of files: 1452
ion beam intensity: ~3-4*10^7 decellerated, stored ions in the beginning, only ~2*10^7 after the big break
