Notes from this meeting:

  • Bubble Chamber is ready to be filled with N2O.
  • Once ready, all safety documents must be forwarded to D. Meekins.
  • The chamber will be shipped with mercury in place but not N2O.

  • Magnet dipole is signed off and out for bids.
  • The Hall Probe has arrived at JLab.
  • Magnet Alignment Fixture is being fabricated by the Machine Shop.

  • The collimator table and holders will be made of aluminum.
  • The table should be wide enough to stack copper bricks to shield the back scattered gammas, if needed.
  • Need a list from Argonne of all the resources needed to run the bubble chamber (cables, power, ...).
