Abstract

Plasma containing deuterium ions is used, for example, to generate neutron flows. Neutrons are generated in nuclear reactions of interaction of accelerated ion beams extracted from deuterium plasma with a solid-state target containing heavy hydrogen isotopes – deuterium or tritium. Deuterium plasma was produced in two types of arc discharge with cold cathode: in a vacuum arc with composite cathode saturated with deuterium and in a low-pressure arc with inlet of gaseous deuterium into the discharge gap. Results of studies of the mass-to-charge fractions of the plasma of these discharges are presented, and a comparative analysis of the methods of deuterium ion generation in such discharge systems is performed.
