Minutes and Action Items
- Reviewed minutes of last meeting
- We looked at Rory's pictures and discussed the 3D model that Stephanie shared
- looking at space on platform, we decided to leave the vertical cable managers so we have some space margin in the future
- Need to develop a dimensional layout of 3D model -- Stephanie
- Note: The chamber currently in the hall has different thickness dimensions than the new ones
- New chambers are 2.09" thick skin to skin
- Need to develop an installation procedure -- Tim/Stephanie
- Need to separate the 2 DS chambers for the electronics RF shielding
- Rory to supply the gauge and dimensions of the shield
- Stephanie to update geometry in 3D model
- Floor rail system design needed to allow CPP to move along with the FCAl platform
- Tim to supply sketch
- Stephanie to create 3D model and drawings
- Dark Room Structure
- Tim to supply sketch for structural needs
- Stephanie to update 3D model and create drawings
- New structural members need to be installed before skin removal
- Next meeting to be 1:30 to avert a time conflict
