Abstract

High intensity and high quality muon beams are needed
for next generation lepton flavour violation experiments.
Such beams can be produced by sending a short proton
pulse to a pion production target, capturing the pions and
performing RF phase rotation on the resulting muon beam
in an FFAG ring. Such a solution was proposed for the
PRISM project and this paper summarizes its current
status. In particular the PRISM task force was created to
address the accelerator and detector issues that need to be
solved in order to realise the PRISM experiment.
Alternative designs for the PRISM FFAG ring are
discussed and their performance compared. The
injection/extraction systems and matching to the solenoid
channels upstream and downstream of the FFAG ring are
presented. The future direction for the study will be
outlined.
