Agenda
- Operations
- Run 62 (HV#4, Si) finished. Fridge will be at room temperature on Thursday
- Overview of HV board leakage issues
- Run 63 (G132, Ge iZIP "pathfinder") about to begin
- Should have all 12 phonon channels connected (bonding scheme)
- Detector has been determined to fit (tightly) in housing, may bump DIBs when cold
- Scheduled to arrive Thursday
- Sources: probably makes sense to install Pb-210 and Am-241 sources internally. (Also will want to activate with the PuBe source.) |
- Probably will not have LEDs, will again mount external LEDs.
- Future 6“ run (1”-thick 5Q device). Detector now at UMN, needs to be wirebonded
- Continued K100 support through both Project and Operations - assume no SNOLAB upgrade
- exploring ideas for improvements without upgrade: float DCRCs for symmetric biasing Proposed Scheme, decrease Rshunt in SQUETs
- Processing and Analysis
- Run 62 (HV#4, Si)
- Phonon collection efficiency: latest data taken at 10, 20, 30, 70, 100 V, still need to analyze
- n,gamma coincidence, first plots
- Run 61, HV#2 (Ge):
- Run 56/Run 54, iZIPv6 analysis, model
- Physics
- low-energy Comptons and n,gamma calibrations with external triggering
- Old/continuing items:
- Run 60, 6“ detector paper - Plan to edit and publish without 5Q data
- Lab infrastructure
- DAQ and data pipe
- DAQ upgrade - discussed with Bruno about IbIs tool development
- Data storage and backup:
- Need to copy all Run 60 and some Run 61 data to SLAC
- Autoprocessing and data organization development:
- currently autoprocessing suspended, no “official” processing for Runs 60, 61, 62
- 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)
- IF (not likely) new DCRC RevC.2 arriving from Bruce in Denver then
- missing resistors on 3 QET channels, we've ordered some
