Agenda

  • Operations:
    • Run 61 (HV#2) status
      • Phonon collection efficiency update
      • Some HV pulse data taken
      • Finishing the run
        • more HV data
          • can we see the lower activation peaks?
          • calculate Luke gain, verify detector bias
          • assess data in hand for signs of deneutralization (took data overnight without flashing…)
        • Characterize “breakdown”
        • Request from Noah et al. to run at higher temperature, see if oscillation region changes
        • Request from Bernard & Bill Page to try modifying prebiasing protocol, take noise data
        • Request from Anthony to try more PuBe neutron data. Have avoided this so far in order to not deal with elevated event rates
      • Run timing
        • Si HV may arrive as early as Friday
          • UPDATE: Matt Cherry having difficulty with wirebonding, won't ship until next week
        • Plan was to finish data this week, warm up over weekend
        • Should we push the run a little longer?
    • Next run, Run 62: HV#4
      • first Si HV prototype. Mask and TES properties will be the same as G101c
      • wirebonded to access all 12 channels
      • comes with two LEDs
      • how to calibrate? can we get a bare Am source? otherwise will have to make due with our Am sources
    • Processing and Analysis
      • Run 60, 6“ detector, analysis
        • Geant sims
        • Measuring capacitance
      • Old items
        • need to get back to work on NSOF, should test whether resolution is improved with new filtering
        • Then work on reprocessing old data
  • Physics
    • Measuring low-energy comptons with 88Y, triggering with external detectors
    • Low-energy NR peaks from neutron capture in Ge, external trigger
  • DAQ and data pipe
    • DAQ upgrade soon. Amy asked if we would be cold still next week to test new DAQ
    • Old/continuing items:
      • Data storage and backup:
        • Need to copy Run 60 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:
        • should work on implementing smart processing so that data with different configurations can be processed automatically
        • should add more info to database, particularly for potential outside manpower
