RAL

MICE Collaboration Meeting, RAL, October 27-29, 2004


Scope

  • Layout

  • Beam line shielding layout

  • Beam line infrastructure

  • MICE support structure


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





PSI solenoid infrastructure

  • New nose peace and temporary lead shielding

  • Cryogenics

  • - layout

  • - specs

  • Site for compressor room

  • Support structure


PSI solenoid nose piece

Nose piece to be replaced

New temporary lead

cover to be added



PSI solenoid compressor room - an example

RIKEN decay solenoid compressor room


Site for compressor room

MICE Hall

ISIS Control Room



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.

PSI solenoid support structure and shielding


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 ?



MICE support structure: Options

HEPCO SL2 stainless steel based slide system

Simple slides arrangement

Platform

Sliding carriages

Low-friction material blocks

Rails

Concrete floor





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.
