Comprehensive Layout and Installation Plan for MICE Beam Line Shielding and Infrastructure

DESCRIPTION

This document outlines the layout and installation strategy for the MICE (Muon Ionization Cooling Experiment) beam line shielding and related infrastructure, as discussed during the RAL MICE Collaboration Meeting held on October 27-29, 2004. Key elements include the detailed design of beam line shielding, support structures, and cryogenic systems. The meeting also addressed radiation shielding, access challenges for compressor installation, and specifications for MICE modules, emphasizing precision and load management. Future steps focus on refining the beam line layout and continuing support structure design.

Presentation Transcript

  1. Layout and Installation Elwyn Baynham, Tom Bradshaw, Paul Drumm, Matthew Hills, Yury Ivanyushenkov, James Rochford and Tony Jones RAL MICE Collaboration Meeting, RAL, October 27-29, 2004

  2. Scope • Layout • Beam line shielding layout • Beam line infrastructure • MICE support structure

  3. MICE and beam line shielding • New round of consultations with ISIS Safety Officer • Beam line radiation shielding: • - Roofed block house; • - Labyrinth –type entrance; • - 1.5 m of steel + 0.75 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. PSI solenoid compressor room - an example RIKEN decay solenoid compressor room

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

  17. MICE support structure: Module weights

  18. MICE support structure: Options HEPCO SL2 stainless steel based slide system Simple slides arrangement Platform Sliding carriages Low-friction material blocks Rails Concrete floor

  19. Forces on Modules for Flip Mode Cases in Stage 6

  20. Forces on Modules for Non-Flip Mode Cases in Stage 6

  21. Maximal Forces on Modules in Stage 6

  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.
