11. 11 Hydrogen R&D: Layout

12. 12 Hydrogen R&D: Layout (2)

13. 13 Hydrogen test cryostat: Concept TH TH Instrumentation mimics what we will need on the absorber for the control system and interlocks Heater will regulate temperature of cryocooler – need redundancy and interlock with compressor Dia.Reservoir =height=290mm

17. 17 Outline Schedule WP1 Initial design: May – August 05 with Review in September 05 WP2 Detailed design and procurement: Aug 05 – Feb 06 WP3 Installation and commissioning: Jan – April 06 WP4 Test Programme: June – Oct 06 Hydrogen system R&D – Schedule

18. 18 Radiation shielding No changes in the layout Paul is working toward a much more reasonable (and cost effective) shielding arrangement.

19. 19 Magnetic shielding No changes in the layout Part of magnetic shielding wall will be installed and used as a support for hydrogen R&D test area platform. Another round of magnetic modelling is required for a full MICE magnetic shielding once position of MICE in the hall is frozen.

20. 20 Support structure – Layout and sequences Add spacer

21. 21 Support structure - Required rail positions MICE Stage IVMICE Stage V Rail positions of downstream detector for Stages IV & V will overlap with final stage VI rail positions

22. 22 Support structure – Super-module Module to module joints to react forces in Z CC/RF module with stiff support structure

23. 23 Support structure – Rail and Force transfer concept Y X Z Magnetic force Traverse in X on rail system to give location to +/- 2mm Jack from rail and position in x-y-z to survey targets on vacuum vessel Shim to blocking plates to locate in x-y-z and react forces Module Jacks Rollers Rails Floor Plate Y support location Shim Beam Axis Survey Target

24. 24 Support structure – Rail-mounting concept

25. 25 Support structure – Force transfer concept - Y

26. 26 Support structure – Force transfer concept - Z

27. 27 Possible MICE rail system

28. 28 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 ? MICE support structure - Specification

30. 30 MICE support structure – Next steps Revise support structure requirements/specs for full MICE - include and analyze requirements of access to every module ( collect information from all technical supervisors) Suggest support structure for Stage 2 (is it different from the one for complete MICE ?) Discuss revised version of support structure at RAL meeting
