Muon Ionisation Cooling Experiment MICE

The Muon Ionisation Cooling Experiment (MICE) is currently under construction at the Rutherford Appleton Laboratory. MICE will prove the technology necessary for muon ionisation cooling. In ionisation cooling, particle beam emittance is reduced by passage through an energy absorbing medium and RF cavities. In its final configuration, MICE will consist of a 5.5 metre cell of an ionisation cooling channel, containing two 4-cavity linacs and 8 coils producing an overlapping solenoid field in an SFoFo arrangement. Detector systems at each end of the cooling channel will measure the 6-dimensional phase space vector of individual muons enabling the reconstruction of the full 6D beam distribution. A schematic of the cooling channel in its final configuration is shown in Figure 1.
