Abstract content

MICE will demonstrate feasibility of the ionization cooling technique proposed to cool the muon beam at a future neutrino factory or muon collider. Position and momentum reconstruction of each muon in a sample by high precision sci-fibre trackers in a solenoid, before and after the cooling cell, provides several alternative figures of merit in addition to beam emittance. Contraction of the phase-space volume of the sample, or equivalently increase in phasespace density at its core, is an unequivocal cooling signature. Single-particle amplitude, defined as a weighted distance to the sample centroid, can be used to probe the change in density in the core of the beam. Alternatively, non-parametric statistics provide reliable methods to estimate the entire phase-space density distribution and reconstruct probability contours. These techniques, robust to transmission losses and sample non linearities, are ideal candidates for a cooling measurement. Preliminary results are presented here.
