Characteristics of neutron production from a 16-27 kJ plasma focus device were systematically studied for device parameters of bank energy, gas pressure, gas impurities and anode geometry. Neutron yields of 10 to the 9th power - to -10 to the 10th power per discharge were obtained with deuterium. Comparison of neutron and hard x-ray production was made using photomultiplier-plastic scintillator detectors. The axial neutron distribution was determined using a paraffin-polyethelene collimator. A good time correlation between the hard x-rays and the neutrons was observed. The dependence of the axial neutron source distribution on pressure was obtained and related to the shape of the collapsing plasma boundary. Author
