Attendance

Minutes

  • Elham: DAQ studies
    • blackening: demonstration of blackening, no more TIR on visual photo
      • much lower energy peak with blackened sides, 5 channels vs 20 channels
      • directionality is different from what will be orientation in MOLLER
      • could put scintillator sideways, but at cost of lower rate
    • Juliette's Sr-90
      • endpoint energy of 546 keV will range out in scintillator
      • maybe get thinner scintillator for triggering
