The temporal development of the hot plasma in a dense plasma focus is studied by X-ray streak photography of ~2 ns resolution time. It is shown that initially a uniform X-ray emitting pinch plasma is formed which subsequently cools down until X-ray emission stops after ~50 ns. At a time of around 100 ns after initial X-ray emission coinciding with the break-up time of the pinch a second burst of X-rays is observed coming from small localized regions. The observations are compared with results obtained from time-resolved shadow and schlieren photography of a similar dense focus discharge (Peacock, Hobby, and Morgan).

Simulation Package

A dense plasma focus is table top machine producing short-lived very hot plasma and can cause nuclear fusion. Lee Model Code is a computer simulation package, which was successfully used in Mather and Fillipov type plasma focus. Lee Model couples the electrical circuit with the plasma focus dynamics, radiation and thermodynamics to simplify the complicated dynamics of plasma focus. This package enables us to simulate and analyze all of the gross properties. In this paper we present the importance of current fitting and the relation of it with other plasma focus parameter and overview of Lee Model Code together with physical basis, scope and the results obtained from the Lee Model Code.
