MICE: The international Muon Ionization Cooling Experiment

The MICE collaboration has designed an experiment made by a section of an ionization cooling channel equipped with particle detectors used as beam diagnostics stations. The channel uses liquid-hydrogen absorbers to provide energy loss and high-gradient RF cavities to re-accelerate the particles; this setup is designed to reduce the beam transverse emittance by >10% for muon momenta in the range 140MeV/c to 240MeV/c. The particle detectors, grouped in two spectrometers before and after the channel, are meant to measure the beam transmittance and emittance reduction with an absolute precision of ± 0.1%. © 2003, Springer-Verlag, Società Italiana di Fisica.
