Agenda

  • Operations:
    • Leak in dilution unit: fixed
      • Redid the MC indium seal
      • Closed IVC and repeated room-temperature IVC-to-dilution unit leak test: no leak
      • Installed 6“ tower then cooled to 77K: no leak from dilution unit to IVC. That is definite confirmation.
    • Beginning Run 60, 6” detector test
      • throughput good, electrical checkout good, cooling to 4K
      • Testing cdmsbats configuration so that 6“-mode data (single charge channel) can be processed
    • Next run: first HV prototype test
      • Current ETA is end of September. Fab at TAMU is finished, will be mounted next week and sent to SLAC for wirebonding, then sent to us
      • About two weeks from now, Run 60 will need to be finished
      • Wirebonding scheme, may not be able to access all side 2 phonon channels
  • DAQ and data pipe
    • Data storage and backup:
      • Run 59 data has been copied to SLAC, need to set up a system for copying incoming data
      • Need to clean up vuk1/vuk2 before they are retired. Emailed Angie, no response yet.
    • 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 since outside analysis manpower (TAMU, Noah) will be joining our analysis crew
      • does it make sense for outside manpower to help with this stuff?
  • Processing and Analysis
    • Update on NSOF
    • Should test whether resolution is improved with new filtering
    • Then work on reprocessing old data
  • Physics
    • Low-energy NR peaks from neutron capture in Ge
