Subject: Energy vs TOF calibration 
Run Number: 17 
DUT: TOF-Cal GSI (TRB)+DOGMA setup(diamond+LGAD)+RaMon 
Beam Energy: 205.2 MeV/u 
Rate Setting: Low Flux Medium 
Particle Type: Helium 
Data: Good 
t-Start: 08:46 
t-Stop: 09:42 
Duration_min: 56 
Frontend:  
Phantom:  
Phantom thickness:  

before run, setups had to be aligned (first slab in slabholder was put in isocentre. However, in this run, no slab was used). Room was closed at 08:10

Beam->Nozzle-> Slabholder->TOF-CAL (TRB)-> DOGMA Setup(Diamond+LGADs)-> RaMon

TRB Setup: 260V bias and 250mA pre-amps, threshold 1000

measured 400kHz with Ramon and only 100kHz with LGADs (third LGAD) and 60kHz accepted trrigger rate

beam was shifted vertically by x? cm? (need to lookup again). So TRB setup was shifted with motors such that the He beam was hitting the centre of the LGADs
