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
