Abstract
|
We present a design concept for a (nu) source from a STORage ring for Muons ((nu)STORM). In this initial design a high-intensity proton beam produces (approx)5 GeV pions that provide muons that are captured using 'stochastic injection' within a 3.6 GeV racetrack storage ring. In 'stochastic injection', the (approx)5 GeV pion beam is transported from the target into the storage ring, dispersion-matched into a long straight section. (Circulating and injection orbits are separated by momentum.) Decays within that straight section provide muons that are within the (approx)3.6 GeV/c ring momentum acceptance and are stored for the muon lifetime of (approx)1000 turns. Muon (and pion) decays in the long straight sections provide neutrino beams of precisely known flux and flavor that can be used for precision measurements of electron and muon neutrino interactions, and neutrino oscillations or disappearance at L/E = (approx)1m/MeV. The facility is described, and variations are discussed.
