Meeting Time and Place =

Reviewed minutes of last meeting
Need to notch steel at bottom to clear connectors -- Stephanie
Look at using a 90° connector -- Rory
Check gas line bending to clear beam left dark room -- Rory
Alignment requirements relative to BL - X&Y ±2mm, Z ±1cm
- Met with survey - need to add x,y and z adjustments for the entire system to achieve this
Desire to have a small block of 5cm lead movable
- can be a local adjustment
- Ring with 7.5cm hole
- ok to have 10cm thick where overlap is
- Holes to be square with radius corner
- Hole size should have 1mm precision
- What should be the size of the hole in the large lead absorber?
Need to check repeatability of detector after moving FCAL platform
Develop a procurement plan for this FY -- Tim
Set up new meeting in 2 weeks
