International Muon Ionization Cooling Experiment

rdf:langString International Muon Ionization Cooling Experiment

rdf:langString The International Muon Ionization Cooling Experiment (or MICE) is a high energy physics experiment at the Rutherford Appleton Laboratory. The experiment is a recognized CERN experiment (RE11). MICE is designed to demonstrate ionization cooling of muons. This is a process whereby the emittance of a beam is reduced in order to reduce the beam size, so that more muons can be accelerated in smaller aperture accelerators and with fewer focussing magnets. This might enable the construction of high intensity muon accelerators, for example for use as a Neutrino Factory or Muon Collider. MICE will reduce the transverse emittance of a muon beam over a single 7 m cooling cell and measure that reduction. The original MICE design was based on a scheme outlined in Feasibility Study II., it was revised significantly in 2014. Pions will be produced from a target in the ISIS neutron source and transported along a beamline where most will decay to muons before entering MICE. Cooling is tested with lithium hydride (LiH) crystals or liquid hydrogen (LH2) cells, magnets are used to focus and analyze the muon beam. MICE will measure cooling performance over a range of beam momenta between about 150 and 250 MeV/c.
