Numerical study on deuteron beams properties generated from dense plasma focus devices in terms of D2 gas pressure using Lee model code

Abstract

Using Lee model code (RADPFV5.16FIB), numerical experiments on deuteron beams properties emitted from five Dense Plasma Focus (DPF) devices (PF1000, TAMU, UNU-ICTP, NX2T, PF400) were performed and compared with each other at low- and high-pressures in a range (1-15 Torr). Full details of the fitting process of the measured and computed currents and deuterons properties as function of pressure for UNU-ICTP DPF device were

presented. Comparisons of I_pinch and flux in terms of pressure among the deuterons emitted from the five devices were computed and investigated to understand the behavior of the ion beam properties when the pressure varies from low to high values. For each device, the properties of the emitted deuterons such as flux, fluence, flux energy, fluence energy, ion beam current density, ion beam current, damage factor, and the energy of deuterons at fitted pressure values were presented and compared to each other. The results of this work are very significant as benchmark references in many industrial applications related to materials processing using plasma focus.
