2- Sept beam test data analysis: media:Analyses_Rashi_Jan2016.pdf media:Analyses_Rashi_Jan2016.pptx
3- Discussion of June 2016 beam test
Notes from this meeting:
- In the simulation, the collimator inner radius is correct (8.0 mm).
- Bubble chamber simulation remaining tasks:
- Complete geometry: add stainless steel cube and flanges
- Add electron beam energy spread and beam size
- Measure fraction of photons that are absorbed in the N2O target as a function of Eγ
- Next Bubble Chamber beam test will measure 19F(γ,α)15N
- Old fluorine chamber has a height of 36 inches. Beamline height on the concrete platform is 27 inches. Beamline height before the platform is 42 inches.
