Notes from this meeting:


  • Bubble Chamber:
  1. Tried few possible solutions to get rid of the mercury droplets on the inner wall of the glass cell but with no luck so far:
    1. Tried coating the inner glass with Teflon
    2. Tried tapping on glass window
    3. Tried strong magnet
    4. Will try laser beam to heat mercury droplets
  2. There is a discussion of using CO2 instead of N2O (now we have to deal with background instead of background).
  3. We may want to use C3F8 for our engineering run this summer. This gas has very similar operational parameters as either N2O or C02.


  • Virginia state limit on mercury is 10 lb. or ( ml).
  • How are we going to ship mercury to JLab? (i.e., in glass cell, or in reservoir).
  • In Virginia, N2O is considered a drug.
