  • PAC jeopardy
    • GlueX experiments are expected to undergo jeopardy review at the next PAC
    • JEF is a Run Group experiment expected to run in parallel with GlueX w/DIRC
    • Not clear what PAC expects for Run Group experiments, but we will prepare slides anyway -- set internal goal of May 1 with updates next week
    • Need simulation with/without DIRC (need to check with Sasha regarding past simulations)
    • Need to refresh physics argument (new B-boson limit plot from Sean Tulin?, work on limit estimates for scalar)
    • Need to look at backgrounds again; S. T. will resurrect scalar_gen code for 2pi0 background
    • What about long-lived particles or invisible decays of B-boson/scalar?
  • Status of hardware shipments
    • No word on status of SICCAS crystals
    • Expect mu-metal shields next week
    • Expect 20 light guide samples (cheaper price!) within next 2 weeks
    • Brass pieces still pending
    • All other hardware pieces needed for module assembly ready to go
  • Tim B. mentioned he needs a circuit diagram for a Gaussian function generator
    • Coordination between Josh and Fernanda B. with Tim B. underway
  • Summer students
    • Not clear what the schedule is for lifting MedCon 6 (lab closed), need to find tasks for people to do remotely.
