Recently it has been proposed to use the 14-MeV neutrons produced in t
he muon-catalyzed dt fusion reaction for the thermonuclear reactors ''
first wall'' materials testing. The results of the Monte Carlo computa
tions of some of the most interesting conceptual schemes of such a sou
rce are presented. It was shown that a neutron flux of about 10(14) n/
cm(2) s, can be achieved in the case of a scheme based on a mirror tra
p with strong magnetic fields, as proposed in this work.
