Subject: 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

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
