Design and expected performance of the MICE Demonstration of Ionization Cooling


Muon beams of low emittance provide the basis for the intense, well-characterised neutrino beams
necessary to elucidate the physics of flavour at a neutrino factory and to provide lepton-antilepton
collisions at energies of up to several TeV at a muon collider. The International Muon Ionization
Cooling Experiment (MICE) aims to demonstrate ionization cooling, the technique by which it is
proposed to reduce the phase-space volume occupied by the muon beam at such facilities. In an
ionization-cooling channel, the muon beam passes through a material (the absorber) in which it
loses energy. The energy lost is then replaced using RF cavities. The combined effect of energy
loss and re-acceleration is to reduce the transverse emittance of the beam (transverse cooling).
A major revision of the scope of the project was carried out over the summer of 2014. The re-
vised project plan can deliver a demonstration of ionization cooling. The design of the cooling
demonstration experiment will be described together with the cooling performance of the revised
