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
TRB Setup: 260V bias and 250mA pre-amps, threshold 1000 DOGMA setup had to be shifted manually to align it with the beam
750kHz with Ramon and only 160kHz with TRB, 44ps single channel res preacalib
300kHz with Ramon and only 40kHz with TRB--> decision to go to low flux high was made
3.5MHz with Ramon and only 600kHz with TRB-52ps single channel res prae calib
