Computational study of five phase modified model for plasma focus device

A mathematical 5-phase focus model (Axial phase, inward radial phase, reflected radial phase, low compression radial phase and expanded phase) was used to study time-variation of the plasma focus formation. In such a way that it shows, the fine structure of plasma dynamics during the radial phase, and yields the emitted radiation from plasma. So this model has the characteristic of a radiation model for the plasma focus. This model has been applied to UNU/ICTP-PFF type plasma focus device (United Nations University/International Center for Theoretical Physics Plasma Focus Facility), and to our AECS-PFF device, by developing a FORTRAN computational program for the neon plasmas, and to show the possibilities of each one concerning the soft x-ray generation.
