RPC Photon Beam Meeting Notes 5/29/02 Attendees: W. Olson, R. Arnold, P. Bosted, S. DeBarger, L. Keller, D. Walz Discussion: 1. A new meeting time was recommended for Thursdays at 1pm, because of Scott's committee requirements. This needs further coordination. 2. The coil winder is available. However, funding isn't available. 3. Ray is working with Scott and Erik to layout the dump magnets 1 & 2 relative angle positioning, vacuum chambers, and energy detector relationships. 4. The layout will be updated to show the vacuum pipe from dump magnet 4 to the collimator, then wire array, toroids and beam dump. 5. The wire array must be under vacuum and, therefore, requires a "pump around" the collimator. 6. Beam stay-out zones are to be looked at. Scott needs to know how much stay clear is required. Bill Olson
