1 Layout and Installation MICE Collaboration Meeting, RAL, October 27-29, 2004 Elwyn Baynham, Tom Bradshaw, Paul Drumm, Matthew Hills, Yury Ivanyushenkov, James Rochford and Tony Jones RAL
2 Layout Beam line shielding layout Beam line infrastructure MICE support structure Scope
3 MICE and beam line shielding New round of consultations with ISIS Safety Officer Beam line radiation shielding: - Roofed block house; - Labyrinth –type entrance; m of steel m of concrete in the direction of the beam; - Beam stopper. MICE radiation shielding: - Shielded doors - Room for possible shielding for ISIS ion source hall; - Room for possible shielding for ISIS control room
4 Layout
5 Beam line shielding layout
6 Solenoid in test position
7 PSI solenoid infrastructure New nose peace and temporary lead shielding Cryogenics - layout - specs Site for compressor room Support structure
8 PSI solenoid nose piece Nose piece to be replaced New temporary lead cover to be added
9 PSI solenoid infrastructure: Layout
10 RIKEN decay solenoid compressor room PSI solenoid compressor room - an example
11 Site for compressor room MICE Hall ISIS Control Room
12 Around MICE hall (2)
13 Possible site for PSI solenoid compressor It seems, the only possible site BUT access for installation is very difficult. Solution: install compressor on the roof of MICE hall.
14 PSI solenoid compressor location
15 PSI solenoid support structure and shielding Concrete ISIS wall Steel shielding
16 MICE support structure: Specification Requirements/specification: - to move (all) MICE modules out the beam (to the side direction) for various MICE stages Accuracy/tolerances: - along the beam +/- 1 mm - across the beam +/- 1 mm Adjustment: - adjustment possibility is required. Locking mechanism: - required. Loads: - max load is 6.65 tonnes. Force transfer function: - gravity force to the floor; - module-to-module axial force to the floor ?

22 Next steps Beam line layout: - continue on the beam line shielding (elevation view, roof ?); - beam line infrastructure layout (including cryogenics); - PSI magnet support structure and shielding design. MICE layout: - add more components (RF system, hydrogen system); - continue on magnetic shielding design. MICE support structure: - finish magnetic forces analysis; - continue on force transfer scheme; - suggest conceptual design for support structure.
