Notes:
- Philip brought up that descrambling appears to not put the detector in the correct position. Dionisio has requested multi asic hardware for properly debugging this.
- Lorenzo presentation:
- We should run at 2.6V, it improved the linearity (both v1 and v2 has been updated to supply 2.6V to the ASIC now);
To Do:
Things to check before beamtime
- Run ePixHR in RIXS DAQ with 5160/120
- Test pedestal and timing scan scripts
- Check that pedestal scan can run with large event numbers per gain mode (for temp stabilization)
- Temp stabilization (configuration time, or add time at start of ever run?) – check during beamtime
- Set temp to 15C/to the degree possible before beamtime
- Test Grafana for live temp readout
- Documentation
- Take test data pre-beam:
- 5 pedestal
- Timing scan without beam
- ACQ start on scope
