  • Lot's to do with laser and cavity.
  • Electron detector     -- Claremont-Ferrand team, Bob, Alex, Sirish
    • Prior to June 15   (when hall opens)
      • Cables for test area
      • Ring and tripod for bench tests -- already done
      • Rig to remove and reinstall E-det -- Neil Wilson (?)
      • Purchase high-intensity beta source.
      • Arrange ACC support for vacuum, E-det removal.
    • June 15 Shutdown
      • July 15, new E-det planes arrive.
      • Repair E-det, perform bench tests     Francois, Alex, Diancheng

    • Obtain crate from Ed J's lab. It goes to L-HRS
  • June 15 Shutdown
    • Re-establish Injector and L-HRS HAPPEX DAQ     -- Bob, Luis
    • Include Qweak Injector crate     -- Paul King
    • Full system rate tests   (we think 2 kHz is doable)
    • Verify ET system works at 240 Hz
    • Helicity-correlated Pedestal studies
    • Re-establish Coil Pulsing
    • New faster PITA Qasy feedback
