Agenda

  • Operations
    • Run 63 (G132, Ge iZIP "pathfinder") in progress.
      • new bias-scan data taken, need to produce seagull plots
      • took some Cf data, haven't looked at it yet
      • more work on complex impedance
      • temperature scan to study parasitic power versus temperature - seems to follow Δ(T^5) law
      • DAQ work in progress (Anthony et al at SLAC)
    • Future 6“ run (1”-thick 5Q device).
      • Detector now at UMN, needs to be wirebonded
      • Side coaxes need wirebond repairs
      • Constructing extender plugs (need to buy 0-80 taps)
      • Source holder, electrode modifications
    • 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
  • 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
