Muon Ionisation Cooling Experiment ( MICE ) – pre-cursor to a neutrino factory

On the GroundAFC Module for MICE – being produced with Oxford University for the MICE experiment

This is a superconducting magnet with a 20litre liquid hydrogen absorber in the centre

MICE

Muon Ionisation Cooling Experiment – hydrogen system

Mice has three 20litre liquid hydrogen absorbers at below 20K

We are providing the storage and delivery system

The R&D phase will use a test cryostat to store the hydrogen until required. The control and operation is quite complex
