  We have investigated the feasibility of using compound materials as target
for muon production by virtue of simulations using a GEANT4 toolkit. A graphite
and two thermostable compound materials, beryllium oxide (BeO) and boron
carbide (B4C) were considered as muon production targets and their muon
production rates for 600-MeV proton beam were calculated and compared. For
thermal analysis, total heat deposited on the targets by the proton beams and
the secondary particles was calculated with a MCNPX code, and then the
temperature distribution of target was derived from the calculated heat by
using an ANSYS code with consideration for heat transfer mechanisms, such as
thermal conduction and thermal radiation. In addition, we have investigated
whether the heavy ion beams can be utilized for muon production. For various
beam species such as 3He2, 4He, 7Li, 10B and 12C, their muon production rates
were calculated and compared with that obtained for a proton beam.
