Features of Neutron Emission in Experiments with Deuterium Hybrid Gas-Puff

Z-pinch experiments with hybrid deuterium gas-puff showed a possibility of efficient production of neutrons and multi-MeV ions. In the experiments on the GIT-12 generator, the total neutron yields are typically above 10 12 at a current of 3 MA. Since the intense pulsed neutron sources are desired for numerous applications as nuclear astrophysics 1 , subcritical experiments 2 , flash neutron radiography 3 , etc., neutron emission from the hybrid Z-pinches deserves to be thoroughly characterized. For this purpose, a comprehensive system of neutron diagnostic is exploited on the GIT-12 generator. Using scintillation detectors, nuclear activation methods, and bubble detectors, the fundamental features of neutron emission, e.g. energy spectrum, angular anisotropy, and number of non-DD reactions are evaluated. The analogous experiments on the HAWK generator allow comparison and scaling of the neutron emission at two different values of the Z-pinch current.
