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
