Abstract—
The features of the generation of neutron and hard X-ray radiation by generators based on plasma focus (PF) chambers are considered. It is shown that the number of hard X-ray (HXR) emission pulses varies in different operations from zero to two for a generator with a current amplitude of 300 kA with deuterium filling, while the time between a feature (a characteristic drop in the discharge current curve after the plasma current sheath is compressed into a pinch) and the time of occurrence of the first X-ray emission pulse is constant to an accuracy of several nanoseconds. The frequency of occurrence of several neutron and X-ray emission pulses when operating on a PF chamber with deuterium–tritium filling (14 MeV neutrons) is analyzed for a generator with a current amplitude of 600 kA. It is shown experimentally that the shape of the neutron pulse has a complex structure with several individual maxima.
