Performance of pinching radius effects to current densities of NX2 plasma focus

Abstract

This paper investigates the pinching radius of ion beams effects throughout the current densities obtained in the truncated end of NX2 plasma focus anode by using the numerical experiments of RADPF code. The code operates from 11 to 14kV of applied DC voltage by using Neon gas with pressure of 1.0-5.0 Torr. Energy beam acquired is studied with reference of the pinch radius and current densities. The radial speed describes the energy transferred and contributed to the drive parameters. The pinching radius of ion beam generated from the system plays as essential roles in the determination of current densities that affects the 552 T. Saktioto et al.energy beam produced. The highest energy beam is 156 J obtained at 4.0 Torr, where the current density is 7.3x10 9 Am -2 and pinch radius is 1.68 mm.
