MICE Hall Layout
MICE Collaboration Meeting, LBNL, February 12, 2005
Paul Drummfor
Yury & the RAL team
2
• Hall layout
• Beam line shielding layout
• PSI solenoid infrastructure layout
• Plans
Access to MICE & ISIS running
Scope
6
MICE module max height
Concrete aperture
Important: The max height from the bottom of the frame to the topof a module should not exceed 3200 mm
Concertina door
Hinged door
Max opening 3200 mm
Max opening 3360 mm

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 doors yes- Room for possible shielding for ISIS ion source hall; yes- Room for possible shielding for ISIS control room yes

Beam line shielding layout
Shielding:
Steel – 1153 tonnes
Concrete – 146 tonnesExisting shielding New shielding: Steel
Movable steel
Concrete

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

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)
