Agenda
- Operations
- Run 62 (HV#4, Si) status:
- Cryo is stable, Tower at 33.5 mK
- DCRC flatlining problem still present, only using two DCRCs
- Much improved IbIs data this run but unfortunately it is still not very stable, continuing to investigate
- HV scans performed and repeated, interesting charge leakage versus HV results
- Calibration:
- Lines from Am source have not been seen yet. Took data overnight Monday and Ba data overnight Tuesday, will compare
- Maybe will need to borrow the Co source for more calibration tests
- Need calibration lines to e.g. verify/investigate IbIs prefactors, calculate phonon collection efficiency, verify Luke gain, and higher-level energy&position reconstruction studies
- Future 6“ run (1”-thick 5Q device)
- housing with 3 DIBs sent to TAMU
- investigating side coax options
- design work on source holder
- Lab infrastructure
- Studying He recovery issues
- Processing and Analysis
- Run 61, HV#2 (Ge) analysis:
- should continue to refine phonon collection efficiency estimate (original synopsis)
- continuing work on fitting and calibrating
- Nick studying position reconstruction
- NSOF work for G106a iZIPv6 data
- Physics
- low-energy Comptons and n,gamma calibrations with external triggering
- DAQ and data pipe
- DAQ upgrade - should ask Bruno about new IbIs tool
- Old/continuing items:
- Data storage and backup:
- Need to copy all Run 60 and some Run 61 data to SLAC
- Need to clean up vuk1/vuk2 before they are retired. Need to ask Angie again when she will finish copying data
- Autoprocessing and data organization development:
- currently autoprocessing suspended, no “official” processing for Runs 60, 61
- clean up database - some info missing. Consider adding additional info
- Possible plan to modify DCRCs (resistor swap) so we can increase front-end gain, improve IbIs (suggestion from Bruno)
- Run 60, 6“ detector analysis - is there more work to do?
- IF new DCRC RevC.2 arriving from Bruce in Denver then
- missing resistors on 3 QET channels, we've ordered some
