Abstract:Both the experimental and theoretical approaches to the X-ray analysis of a dense plasma focus are explored in this research. Diagnostic techniques and analytical tools were developed to analyze the X-ray production of the dense plasma focus and to optimize its output. Time-resolved temperatures were measured with dispersive rather than filtering X-ray analysis. Densities were measured with a nitrogen interferometer. A radiative-collisional one-dimensional simulation of the plasma focus pinch was constructed with emphasis on the radiation emission from the plasma. The occurrence of radiative collapse was anticipated with the computer simulation and observed experimentally in the case of heavily seeded neon discharges. The addition of an axial magnetic field to stabilize the focus pinch was found to have beneficial effects on the X-ray emission in terms of reliability and improved source geometry.
