Low flux carbon did not work
1µs EFE, 30s Extraction, Deg100
we tried different energies (402.MeV/u)-> 120 MeV/u, but unfortunately we did not get any beam |

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 |
