Infrared Emission and Scattering from the Dense Plasma Focus

This report describes investigations of the dense plasma focus designed to study turbulent processes. A CO2 laser collective scattering experiment with a high sensitivity was performed to measure the collective fluctuation spectrum. Scattering was observed from small, overdense regions and was correlated with micropinches seen in soft X-ray photographs. Bremsstrahlung was measured near the electron plasma frequency to determine a possible role for beam plasma instabilities. Only thermal bremsstrahlung levels were detected. (Author).
