1- Bubble Chamber progress at Argonne: media:Hg_Chamber_5Nov2014.pdf

2- Summary of radiator optimization modeling efforts: media:radiator_summary.pdf

Notes from this meeting:

  • Bubble Chamber:
  1. New glass cell is fabricated and re-assembling of chamber has started
  2. There will be one spare cell
  • Modeling effort:
  1. All drawings are in: M:\bubble\grames\JLAB_Released_Bubble_Drawings
  2. Study sensitivity of beam position on radiator with collimator included in geometry
  • Bubble Chamber Beamline:
  1. Beamline is commissioned and all components are working fine
  2. Had 10 μA CW on radiator/dump
  3. For the time being, there is 10 μA CW administrative limit on beam to Bubble Chamber beamline
  4. Next: measure beam energy and neutron background, if any
