1. 1 MICE Hall Layout MICE Collaboration Meeting, LBNL, February 12, 2005 Paul Drumm for Yury & the RAL team

2. 2 Hall layout Beam line shielding layout PSI solenoid infrastructure layout Plans  Access to MICE & ISIS running Scope

5. 5 Layout (cross-section view) Drawing by Tony Jones

6. 6 MICE module max height Concrete aperture Important: The max height from the bottom of the frame to the top of a module should not exceed 3200 mm Concertina door Hinged door Max opening 3200 mm Max opening 3360 mm

7. 7 MICE and beam line shielding Consultations with ISIS Radiation Safety Officer: Implemented: Beam line radiation shielding: - Roofed block house;no - Labyrinth –type entrance;yes - 1.5 m of steel + 0.75 m of concrete in the direction of the beam;yes - Temporarily shielding block (1.5 m of steel + 0.75 m of concrete)yes + 1 m of concrete (very recent demand) );not yet - Beam stopper.Yes(!) MICE radiation shielding: - Shielded doorsyes - Room for possible shielding for ISIS ion source hall;yes - Room for possible shielding for ISIS control room yes

8. 8 Beam line shielding layout Shielding: Steel – 1153 tonnes Concrete – 146 tonnes Existing shielding New shielding: Steel Movable steel Concrete

9. 9 Solenoid in test position Temporary shielding block

10. 10 MICE and beam line shielding: Problems and solutions Problem: Very heavily shielded beam line  high cost  can MICE afford it ? But do we really need that heavy shielding ? Solution: Calculate doses in the MICE hall for the worst scenario case Optimize the shielding Discuss the issue again with ISIS Safety Officer

11. 11 PSI solenoid infrastructure Magnet preparation for shipment : - New nose piece and temporary lead shielding (design completed). - Need to agree few technical issues for transport with PSI. Cryogenics - layout (suggested) - specs (ready) Site for compressor (suggested) Support structure (conceptual design completed)

12. 12 PSI solenoid nose piece Nose piece to be replaced New temporary lead cover to be added

14. 14 PSI solenoid cryogenics layout He Transfer lines He Refrigerator Compressor

15. 15 PSI solenoid support structure and shielding Concrete ISIS wall Steel shielding

16. 16 Hall Layout: Plans Finalize shielding layout (after the agreement with ISIS Radiation Safety Officer is reached) Add RF system infrastructure Modify layout for hydrogen system Add new support system (talk by Elwyn)
