rate only 10Hz, stopped run, room request and rewired trigger.

NOTE: Problem was caused by operators: Optics were not set correctly after ramping up energy from 62.4 to 252.7, not trigger cable

bias run and threshold optimization

mean rate was O(100kHz)

Start: 06:40 O(100kHz)

Bias voltage SiC: 800

Bias voltage Si: -150

From a beam perspective the Si detector was the first target, on oscilloscope  channel 1, SiC was the second target connected to oscilloscope channel 3.

Triggering source was the Si detector.

The compliancy of the SiC SMU triggered after approx. 50% of the events had been acquired after this event the HV for the SiC HV was shut down.

Data was stored on the HiBPM-Osci-2 NUC under c:\measurements

Fluence loss measurement 11.12.2021

Tracker timing wrong, latency too low, peak at 0 --> changed lat from 40 to 41 for next run.

Rate, Beta nominal, ERROR tracker  -> reset TLU

WET measurement of PMMA slabs also used for TOF-CT (GSI)

4cm PMMA
"Accumalte Charge"

PMMA was activated. Had to wait ~10-15min after measurement

ASIC: TH 1300 again for verificationn - still too many noise hits
BEAM OFF, for TH check

Rate, now Beta nominal again, looks like old setting 4-6 Mhz
