It analyzes JPARC's capabilities and proposes extensions to approach the ultimate high-intensity proton source for muon colliders and neutrino factories.

Findings

JPARC's beam parameters meet pulsed intensity goals.

Extensions could evolve JPARC towards the ultimate source.

JPARC can serve as a stage 1 for future high-power facilities.

Abstract

An "ultimate" high intensity proton source for neutrino factories and/or muon colliders was projected to be a ~4 MW multi-GeV proton source providing short, intense proton pulses at ~15 Hz. The JPARC ~1 MW accelerators provide beam at parameters that in many respects overlap these goals. Proton pulses from the JPARC Main Ring can readily meet the pulsed intensity goals. We explore these parameters, describing the overlap and consider extensions that may take a JPARC-like facility toward this "ultimate" source. JPARC itself could serve as a stage 1 source for such a facility.
