Category: Runs 
Subject: Second measurement with 2 hrs storage time 
Electron cooler was off here. Thus, this measurement is not what we needed.
(in the picture below, it can be seen that the beam is not cooled)


beam: 205Tl81+ (no scraping)
energy: 400 MeV/u
storage time: 2 hrs

purpose: data with TARGET ON

Detector position (CsISiPHOS):  out of the ring
Detector position (MWPC):       mm

run start at 01:48 , first file: run0287.lmd
file running:    0287.lmd

_______________________________________________________________________________

time when accumulation starts: 04:45
time when storage starts: 04:55
time when storage ends: 06:55
I_cooler during storage time: 10 mA

I_cooler =  mA


I_SIS: 1.8e9      
ESR particles after stacking: ~e5  
Number of stackings: 20
Target ON density:   4e12
Target on time: 06:56:30
Target off time: 07:06:30
Target on time for measurement: 10 mins (by local mode)
