  • Lab Update
    • Ending the run, warm-up starting ~Monday
      • Will go back to normal 4K heatsinking
      • Will assess/replace broken phonon channels (1 dead, 1 dying)
    • Now collecting data on HV noise vs. bias
      • HV scans using counter-bias build-up
      • Constant HV using HV slow drift to cancel counter-bias
        • Want stats to see low 241Am lines and calibrate noise width
    • cdms2 rebuild
      • cdms2 (DAQ machine) was getting slow and may have been causing frequent DAQ crashes
      • Boot disk was dying, replaced it and rebuild cdms2 os
      • Some small issues getting cdms2 set up after rebuild, but DAQ is mostly working, no MIDAS crashes so far
  • General Updates?
