  2. Action Items
  3. Monitoring
  4. BCAL
    1. SiPMs Update
      • Three units (SN: 80 JLab, 219 JLab, 1933 USM) were found to be "hazy" during installation onto the readout assemblies at JLab.
      • We have original photos from unit at USM after some cleaning. No degradation in performance was observed
      • Media:SiPMHaze1.JPG SiPM 1933 with "haze" at USM after cleaning
      • Media:SiPMHaze3 atJLab.jpg SiPM 1933 with "haze" at JLab during assembly
      • Media:SiPMHaze2.jpg SiPM 1933 with "haze" at JLab during assembly (zoom)
      • Likely the epoxy covering the sensor has been affected during handling. Carl is retesting them. Will keep these as spares.
  5. Reconstruction and Simulation
    1. Electrons from J/psi
  6. TDR update
  7. Calibration of Calorimeters
  8. Any other business
