Robert | Runs | data run for Li like |
We startet run on Tuesday 2 am with ~4E7 decellerated ions.
We get a count rate of ~40 cts per hour in the line.
Target density: ~1.5E12 part/cm2 |

Robert | Runs | He-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 |
