Agenda
Meeting room = Cebaf Center F227
General
- Hall A will start earlier than originally planned - Monday, November 25
- Hall will be locked up for high current test Wednesday or Thursday
Electron detector
- Detector installation
- motion ok
- noise from Analog boards about +/-5 mV
- might be issue with plane A (2uA) and D (12uA), plane B 25 nA, meter for thick plane might have died from radiation
- adapters still need to be done
- VXS crate installed with VETROC, VTP installed, need to configure NFS mounts to work
- almost ready to look at cosmics
- QWAD adapter boards
- Counting DAQ
Laser
- Mirrors replaced
- Entrance scans
- Cavity birefringence scans
- Polarization strategy
Photon Detector
- PREX checks - complete (?)
- CREX preparations
Analysis
- ACC0 - laser-cycle analysis
- ACC4 - laser cycle analysis
Minutes
- Electron Detector
- Motion is working
- Adaptors for cables to VETROC will take 2 weeks
- QWAD adaptor boards ordered
- Counting DAQ crate now in hall
- Laser
- Polarization leaving the cavity has low DOCP. Is this caused by the mount causing birefringence in the mirror surface or substrate? Something worth testing.
- Photon detector
- 16 mV constant LED during LED linearity tests.
- No spare PMT available. Will use PREX tube after doing all the linearity measurements that we think are necessary.
