  • Preparation for MOLLER tracking meeting - status
    • Need to go back to reviewers and ask what they meant, if we need to
    • create a timeline for next 6 months
    • Radiation dose estimates/material irradiation summary
      • have located some "hot spots"
      • need to convert to doses
      • compare to radiation hardness for various materials (epoxy, insulating tape)
      • quantify known materials, is it good enough for MOLLER
    • Upstream sensitivity studies summary
    • Beamline fringe field effects
    • MIT activities
      • impact of environmental variations
        • expanding and contracting uniformly (that's how water system is being designed)
        • heat load on hot day - just run hotter
        • we need to cool our water anyway - our refrigerator design
      • floor loading - probably not a concern (each component less than what crane can lift)
        • spring of '18 - would floor sagging affect physics?
        • shielding around target bigger issue
        • dialogue between MIT and survey group
        • does target sinking affect rest of experiment?
    • beamline - Silviu's designer
      • downstream of vacuum vessel - exit window
      • coupling between vacuum vessel and beamline
  • Also need to list things that we want to keep working on that aren't on the list
    • collimator supports
    • movable collimator - needs work - concept based on SLAC design
      • need space where shielding might exist right now
      • linear stage and hard stop
    • water-cooled collimator
      • same system as coils
      • feasibility with cooling and physics
    • budgetary bids only
    • upstream vacuum vessel
      • inner-photon collimator - independent of motion of chambers
  • Test coil status/homework
