Agenda:
1- Bubble Chamber progress at Argonne
2- Detection features of new bubble chamber: media:Detection_features_new_bubble_chamber.pdf
Notes from this meeting:
- Bubble Chamber:
- Showed bubbles distribution from N2O with mercury as buffer liquid using PuC neutron source.
- Plan to measure temperature gradient across the glass cell.
- Regarding CO2: it is possible to suppress the 12C(γ,α)2α signal but 13C(γ,n)12C background will be significant - Not an option.
- Test chamber with C2F6 as the super heated liquid.
- Schedule:
- Reconfigure bubble chamber beamline in the first two weeks of July.
- Chamber arrives JLab in middle of July. Move to Injector. Install and align.
- Mercury we be installed in chamber at Argonne.
- Brad arrives on August 3. Cool and pressurize with C2F6. Complete safety reviews.
- Beam on chamber in the second week of August filled with C2F6. Beam kinetic energy = 4.0 - 5.5 MeV.
- Remove C2F6 and fill with N2O during the last two week on August.
- Beam on chamber in the first two weeks of September
