Title Beam Dynamics in an Ionisation Cooling Channel
Abstract The Neutrino Factory has been proposed as a facility to provide an intense source of neutrinos suitable for the measurement to unprecedented precision of neutrino oscillation parameters and a possible CP violating phase. In the Neutrino Factory, neutrinos are produced by the decay of a muon beam with 20-50 GeV energy per muon. Initially, the muon beam occupies a large volume in phase space, which must be reduced before the beam can be accelerated. The proposed method to achieve this is to use a solenoidal-focussing ionisation cooling channel. In this thesis the physics of the cooling channel is described including the cooling effects of different materials and the beam optics of solenoidal focussing and radio frequency cavities. The Muon Ionisation Cooling Experiment is de- scribed, in which a section of a long cooling channel will be constructed at the Rutherford Appleton Laboratory (RAL) in Oxfordshire, the cooling performance measured and compared with computer simulation. The simulation of the cooling channel in the G4MICE code is detailed and the accuracy of such simulations is investigated. The beam dynamics of the simulated cooling channel is examined in longitudinal and transverse phase space and linear resonances are studied. The cooling performance of the channel is examined including the effects of realis- tic curved windows. The cooling measurement is simulated and the measured cooling performance is compared with the true cooling performance.
