Consideration is given to the possibility of creating a plasma neutron source based on the electromagnetic trap with a multipole magnetic field configuration. The number of magnetic slits is reduced down to two axial holes, through which high-energy electrons are injected. The deuterium plasma target of 2·1014 cm−3 density is formed by electronic ionization of deuterium arriving at the trap. Tritium ions are produced on the edge of the potential well and are then accelerated by the electric space-charge field of electrons. With a tritium rate of 10−4 g/s the source is capable to produce up to 5·1018 n/s with a fluence of 2·1014 n/cm2·s on the surface of specimens under irradiation.
