- Solving DAQ crashing issues;
- Bringing up gain calibration using florescence in the Marietta;
- Measuring temperature for the camera;
- Analysis and performance - ePixHR:
- analysis plan and data overview: Breakdown of measurements performed.xlsx
- Banding issue;
- CompEnOn stepsize;
- Gain and Offsets at different run and daq trigger rates;
Notes:
- Item 1:
- Alex mentioned he is not necessarily seeing drift in dark run data when biasing to 20V;
- Pedestals look stable, but we see original negative drift down;
- over longer time scales we are seeing different pedestal values suggesting a longer-term drift happening. Should be evaluated;
- Significant banding observed across the ADC range;
- We need temperature monitoring to better evaluate the drifts;
- We need to measure the pedestal drift with temperature;
