Particle Production for a Muon Storage Ring:
I. Targetry and r/p Yield *
Fermilab, P.O. Box 500, Batavia, IL 60510, USA '
Efficient production and collection of a large number of muons is needed to make
a neutrino factory based on a muon storage ring viable. Results of extensive MARS
simulations are reported for 2 to 30 GeV protons on various targets in a 20 T hybrid
solenoid, followed by a matching section and decay channel. Part I describes pion
and muon yields, targetry issues, and beam energy and power considerations. Part II
describes radiation loads on targets, the capturing system and shielding.
Key words: Neutrino factory, targets, beam capturing, pion and muon yield

To achieve adequate parameters of a neutrino factory based on a muon storage
ring  it is necessary to produce and collect large numbers of muons. The
system starts with a proton beam impinging on a thick target sitting in a
high-field solenoid (20 T, 1-m long, aperture radius Ra=7.5 cm), followed by
a 3-m long matching section and a solenoidal decay channel (1.25 T, 50-100 m
in length, Ra=30 cm) which collects muons resulting from pion decay [2,3].
Optimization of beam, target and solenoid parameters were done over the
years with the MARS code [4,5] for a p+ -collider project [2,3,6-9]. This paper
focuses on parameters needed for a muon storage ring and briefly describes
the results of extensive MARS simulations of 7f/p-yield (Part I) and radiation
fields in the target station and capturing system (Part II) for 2 to 30 GeV
proton beams. Preliminary results were given in Ref. [1,9].
