  • Engineering status
    • Updates on Tank Construction
    • Updates on Stand Construction
  • Outstanding items that need to be ordered/built/procured
    • Status of current orders:
      • MaPMTs (Need ordering institution)
      • Mirrors (ECI film ordered)
      • Electronic summing board board (Final quote determined, 2-week lead time)
      • Gas regulation system (ordered, still needs to be assembled)
        • What extra care do we need for gas tank, plumbing from tank on the floor to tank on table should bbe straight forward.
      • Cabling before patch-panel
        • What patch cables do we need? 134 BNC patch cables? Can we use cables from the previous prototype? How about SHV? Do we need 70 SHV patch cables also?
      • Cabling after patch-panel
        • Do we have the necessary BNC and SHV? Can we find the lemo cables? (Jian-Ping seems to think we can find the lemo cables at JLab)
  • Preparation of Cosmics test.
    • Space at the lab?
    • Electronics and cables ready?
    • Schedule for bench testing calorimeter blocks and scintillators.
  • MaPMT pixel test with wavelength shifter coating
  • Documentation for device
    • Status of SOW's for Argonne
    • Safety documentation for JLab
    • Alignment, calibration, and commissioning procedures.
      • Lasers to align to beam-line.
    • Heavy gas fill procedure
    • Run Plan
    • Kinematics switch timeline/plan

List of topics for meeting today:

  • Engineering status
    • Updates on Tank Construction
      • Is there adequate space in the current design for the scintillator arrays? Image of Design
    • Updates on Stand Construction
  • Outstanding items that need to be ordered/built/procured
    • Status of current orders:
      • MaPMTs
      • Mirrors
      • Electronic summing board board
        • Use MCX connectors with MCX to BNC conversion cables? $2400 total cost on entire MCX to BNC out, saves time on assembly/labor.
