Agenda
- Operations
- Run 64 run (S1502, Si 6“ diam 1”-thick 5Q device).
- Am sources: adjusted collimators
- detector respacing, wirebond repair, fixing shorts…
- Playing around with Ramo weighting potentials
- exploring ideas for improvements without upgrade: float DCRCs for symmetric biasing Proposed Scheme, decrease Rshunt in SQUETs (had a look at this, a little hard to set up: SQUET picture), sidewall sources?
- Processing and Analysis
- Run 63 (Ge iZIP pathfinder)
- need to analyze bkg data (phonon collection efficiency) and Cf data
- Run 62 (HV#4, Si)
- more IbIs automation work
- n,gamma coincidence: seeing weird glitches, periods where the events show some phonon channels not in sync with others (then sync returns again)plots
- Run 61, HV#2 (Ge)
- Run 56/Run 54
- Lab infrastructure
- plans to try to improve helium recovery
- add length of copper tubing to recovery line, to warm helium on the way to the meter. Almost done.
- maybe try to recover helium while waiting for the transfer stick to cool before hookup
- Old/continuing items:
- Run 62 (HV#4, Si) post-mortem: two “bad” channels seem not to be wiring problems, maybe the problem is on the detector (photos)
- 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
