Phase rotation channel design with induction linacs

Two models of the phase rotation channels of the neutrino factory were designed with a solenoid transport system and the induction linac acceleration system. One model has the one stage induction linac channel, and another model has two stages of the induction linac channels and an absorber and drift space in between them. Major figure of merits of the channel are the particle ratio of muons over primary protons, the momentum spread and the muon polarization correlation to the arrival time at the end of the phase rotation channel. The μ/proton ratios were 0.25 and 0.13 for the single stage and the double stage induction linac channels, respectively. The effective muon polarization, 〈helicity2〉, was 0.16 and the muon polarization correlation was 0.23/(100 ns) for the single stage induction linac model.
