Minutes
- Elton met with nick and discussed LV box. Need to make bracket smaller (1/16" thick) boxes should be on top-north corner of each chamber
- For fiducializing chambers, all four edges or bolt holes can be used to find center. Machining is very accurate
- Proposed chamber orientation good - horizontal x-ray port DS, Vertical x-ray port US
- Rory/Elton requested 4 scintillator paddles, 2 BL and 2 BR in vertical position equally spaced (15" oc). To be held by light guides, maybe a V block
- Lead Target needs to be pressed flat since it is malleable and has the center protruding

- Tim - Get with S&A group to discuss chamber fiducialization and alignment
- Rory to flatten lead target
- Stephanie to model and place scintillators and attachments
