Neutronic Problems of a Compact 14 MeV Plasma Neutron Source

Neutronic problems connected with the design of a compact 14MeV neutron source for fusion material research based on a plasma mirror are treated. In particular it has been demonstrated, that further construction efforts are necessary to comply with the established radiation limits for the magnetic system. Further it ist not possible to raise the useful high energy flux by arranging reflectors. If one of the source areas of the machine is equipped with a moderator, a thermal neutron source with a flux of about 5 1014 n cm-2 s-1 can be achieved.
