MICE Radiation Shielding:Status
1.
Option “no block house” was considered and agreed at the last Collaboration
meeting.
2.
This concept was approved by Paul Wright, the ISIS Radiation Safety Officer, at
the meeting on the 12th of January at RAL.
Paul Wright’s comments:
- doors: ideally should be lead sliding doors;
- local shielding for doors to protect against radiation
scattered by walls and the ceiling;
- beam-line shielding requires careful consideration.
More detailed recommendations on both the MICE hall shielding and the
beam-line shielding have been promised.
3.
New MICE layout is under way. The latest version by Tony Jones is shown on the
next slide.

MICE Radiation Shielding:Next Steps
• Get recommendations from ISIS Safety Officer and implement them into
MICE layout.
• Complete preliminary design for magnetic shielding and implement it
into MICE layout.
• Complete preliminary layouts for other systems including cryogenic
plant, hydrogen system and RF power supply system.
See next slide for an example of preliminary cryogenic system layout.
