  • Any A1/d2n scheduling updates?
  • Engineering status
    • Updates on Tank Construction
      • New cradle design with 80/20:
        Fig. 1: 80/20 cradle design
      • LAPPD box has leaky BNC feed throughs. Not sure about MaPMT box.
    • Updates on Stand Construction
  • Outstanding items that need to be ordered/built/procured
    • Status of current orders:
      • MaPMTs (Ordered via ANL)
      • Mirrors (ECI film shipped, expected today/tomorrow)
        • Still need to do mirror assembly, i.e. attach film to carbon fiber blank. We have lexan film with no reflective coating to test.
      • Electronic summing board board (Ordered, board is printed and currently in component assembly)
        • Also will need to have MCX connectors attached (done at JLab, if Jack hasn't disowned us)
      • Gas regulation system (In hand, being assembled)
      • Cabling between prototype and patch-panel
        • Cabling (Components are in hand and set up to make 150 8' BNC patch cables and ~30 patch SHV, construction this week)
        • Do we have the additional SHV cables at the Lab?
      • Cabling between patch-panel and DAQ
        • Do we have the necessary BNC and SHV? Can we find the lemo cables? (Who to ask, Alex?)
  • Tank delivery estimate?
    • Assuming 2-weeks from today (Jan 20th). If we are ready sooner, we will deliver ASAP.
      • I'll likely be delivering the tank to JLab alone, so I will need some help loading and unloading the van.
  • Preparation of Cosmics test.
    • Space at the lab?
    • Electronics and cables ready?
    • Schedule for bench testing calorimeter blocks and scintillators.
  • Documentation for device
    • 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

      • 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.

    • Electronics and cables ready?
    • Schedule for bench testing calorimeter blocks and scintillators.
