	High intensity and high quality muon beams are needed for the 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.

	Potential upgrades to the ISIS accelerators at RAL in the UK to provide proton beams in the few GeV and few MW range could be envisaged as the starting point for a proton driver shared between a short pulse spallation neutron source and the Neutrino Factory. The accelerator chain for the spallation neutron source, consisting of an 800 MeV H⁻ linac and a 3.2 GeV rapid cycling synchrotron (RCS), is currently being designed and optimised. The design of the RCS for the final stage of acceleration, which would increase the final beam energy of the dedicated pulses to feed the Neutrino Factory pion production target is presented. The feasibility of the final bunch compression to the necessary nanosecond range is also discussed.

Potential upgrades to the ISIS accelerators at RAL in the UK to provide proton beams in the few GeV and few MW range could be envisaged as the starting point for a proton driver shared between a short pulse spallation neutron source and the Neutrino Factory. The accelerator chain for the spallation neutron source, consisting of an 800 MeV H⁻ linac and a 3.2 GeV rapid cycling synchrotron (RCS), is currently being designed and optimised. The design of the RCS for the final stage of acceleration, which would increase the final beam energy of the dedicated pulses to feed the Neutrino Factory pion production target is presented. The feasibility of the final bunch compression to the necessary nanosecond range is also discussed.
