Title: Large acceptance muon storage rings for neutrino production: Lattice design

Abstract

The possibility of achieving the high muon fluxes suggested in recent work on muon colliders has revived interest in the idea of using muon storage rings for neutrino production. Through proper design of the lattice, a significant fraction of the stored muons can be converted into an intense, low-divergence beam of neutrinos. This work examines the incorporation of a long, high-beta straight section for production of neutrino beams into a lattice which is otherwise optimized for transverse and longitudinal admittance. The ring must be able to accept a very large emittance and large momentum spread muon beam.

  • Five energies, 250, 100, 50, 20, and 10 GeV, have been explored in the design of a muon storage ring for neutrino-beam production. The ring design incorporates exceptionally long straight sections with large beta functions in order to produce an intense, parallel neutrino beam via muon decay. To emphasize compactness and reduce the number of muon decays in the arcs, high-field superconducting dipoles are used in the arc design.

  • A muon storage ring can provide electron and muon neutrino beams of precisely knowable flux which are excellent probes for /upsilon/ oscillations. Constraints on storage ring and injection design are described. Sample muon storage rings are presented and compared with parasitic use of the Fermilab p precooler as a /mu/ storage ring. ''Stochastic injection'' with injected pion beam decaying to circulating muon beam is favored. A practical possibility may be a low-energy (1 Gev) ring matched to a medium energy proton injector (8 Gev Booster). 7 refs.
  • Intense muon sources for the purpose of providing intense high energy neutrino beams ({nu} factory) represents very interesting possibilities. If successful, such efforts would significantly advance the state of muon technology and provides intermediate steps in technologies required for a future high energy muon collider complex. High intensity muon: production, capture, cooling, acceleration and multi-turn muon storage rings are some of the key technology issues that needs more studies and developments, and will briefly be discussed here. A muon collider requires basically the same number of muons as for the muon storage ring neutrino factory, but would require more cooling,more » and simultaneous capture of both {+-} {mu}. We present some physics possibilities, muon storage ring based neutrino facility concept, site specific examples including collaboration feasibility studies, and upgrades to a full collider.« less
  • High-intensity neutrino beams could be produced using a very intense muon source, and allowing the muons to decay in a storage ring containing a long straight section. Taking the parameters of muon source designs that are currently under study for future high luminosity muon colliders, the characteristics of the neutrino beams that could be produced are discussed and some examples of their physics potential given. It is shown that the neutrino and antineutrino beam intensities may be sufficient to produce hundreds of neutrino interactions per year in a detector on the far side of the Earth.
