Description
Summary:The Muon Ionisation Cooling Experiment (MICE) aims to make a proof of principle measurement of ionisation cooling of muon beams for use in a future neutrino factory or muon collider. To complete this measurement, two precision scintillating fibre spectrometers have been constructed, for which data acquisition systems and calibration procedures have been developed. In addition, reconstruction algorithms have been written and the performance of the detectors tested with cosmic rays. To explore the behaviour of the MICE cooling channel under various conditions associated with the beam emittance and RF phase, a method of particle weighting using approximate Voronoi diagrams was used and shown to be a viable method of statistical weighting. Investigations have also been made into approximating the MICE cooling channel with transfer matrices, using a neural network approach to fit the data. This showed that whilst the effect of the magnetic field on the particle trajectory can be accounted for in a simple transfer matrix, the inclusion of stochastic effects is essential to an accurate approximation of emittance transferral through the channel.
