Subject: run entry - run099 
Year:  
open file : run099

beam: 124Xe54+
energy: 10 MeV/u

SIS intensity increased factor 2: 1.25e9, also Sergey tried to optimize these phase shift losses. 

purpose: data with TARGET ON and SCRAPER in scraping poisition--> We expect to cut the Rutherford for now on.

Detector position (Si): -27 mm
GE01DD1IG position (Scraper): 9 mm

run start at 10:12, first file: run099_0001.lmd
run stop  at , last file:  run_0xxx.lmd

ON Rates
Si_X:       2 Hz
Si_Y:       2 Hz
Xray_35:    1 Hz
Xray_90:    70 Hz
Xray_145:   22 Hz
BaF_OR:     ---

Si voltage:          60.02 V  
Si leakage current:  4.17 uA with spikes for 3s long after injection roughly 10uA


SIS particles before:           2.7e8
ESR current at injection:       5.8e7?? (we see a bug: like the number of particles increases in the bunching phase)
ESR particles after decel.:     1e7 (it is hard to catch exactly)
Target ON density:              5.4e13
