Muon Storage Ring Neutrino Sources:
A Brief History/Bibliography

1.  D. G. Koshkarev, "Proposal for a decay ring to produce
    intense secondary particle beams at the SPS", 
    CERN/ISR-DI/74-62, 1974.
    Synopsis: Proposed a general ring to capture pi/K and 
    allow them to decay. Considered neutrino beams, including
    those from the muon decays. Calculated fluxes, although 
    not with the correct expressions for muon decay. The fluxes
    were very small. Physics motivation not considered.

2.  D. Cline and D. Neuffer, "A muon storage ring for neutrino
    oscillation experiments", AIP Conf. Proc.. 68, 846 (1980).
    Synopsis: Proposed exploiting the FNAL antiproton debuncher
    as a muon decay neutrino source with a 100 ton detector 0.5 km 
    from the source. Quotes event rate. Does not consider physics 
    potential. Ascribes idea to: 
2a. Stan Wojcicki, unpublished (1974), and 
2b. T. Collins, unpublished (1975).
    
3.  W. Lee (spokesperson) et al., FNAL Proposal P860, "A Search for
    neutrino oscillations using the Fermilab Debuncher", 1992.
    Synopsis: Proposed experiment at the FNAL antiproton debuncher
    as a muon decay neutrino source for a short baseline search for
    nu_e -> nu_tau oscillations. Considered physics case, and presented
    fluxes and interaction rates. However, these were marginal, and
    the experiment was not approved.

    S. Geer, "Neutrino beams from muon storage rings: characteristics
    and physics potential", FERMILAB-PUB-97-389, 1997; Presented in 
    the Workshop on Physics at the First Muon Collider and Front-End
    of a Muon Collider, November, 1997, and Published in 
    Phys.Rev.D57:6989-6997,1998.
    Synopsis: Proposed using a  muon source of the type being developed
    for muon colliders, coupled with a muon storage ring neutrino source.
    Calculated fluxes and rates versus baseline length, muon energy, angles,
    and polarization. Considered oscillation physics potential. Proposed 
    tilting the ring at large angle to shoot through the Earth. Proposed
    searching for nu_e -> nu_mu and nu_tau oscillations by searching for
    wrong-sign muons. Proposed exploiting the muon polarization to turn 
    on/off nu_e processes. Rates large and physics reach interesting.
    Pointed out that at high energies, event rates are very large enabling
    neutrino physics with small and highly instrumented detectors.


    The first group-type study of physics at a neutrino factory was 
    conducted at CERN and yielded the report:
    B. Autin, A. Blondel, J. Ellis (editors); "Prospective Study of Muon 
    Storage Rings at CERN", CERN 99-02, April 1999.
 
    The first indication that CP violation might not be completely out 
    of reach at a neutrino factory was included in the CERN report, and 
    published separately by the relevent authors: 
    A. De Rujula, M.B. Gavela, P. Hernandez; hep-ph/9811390,
    Nucl.Phys.B547:21-38,1999.
