Numerical Studies on Pinching Radius Effects to Current Densities of NX2 Plasma Focus
The pinching radius of ion beams effects are observed throughout the current densities obtained in the truncated end of NX2 plasma focus anode. The numerical experiments were carried out using RADPF code operating from 11 to 14kV of applied voltage using Neon as the filling gas with range of pressure 1.0 5.0 Torr. Energy beam acquired is studied with reference of the pinch radius and current densities. The theoretical calculations are studied. The radial speed will describe the energy transferred and will contribute to the drive parameter. The pinching radius of ion beam generated from the system plays an essential role in the determination of current densities that affects the energy beam produced. The highest energy beam, 156 J obtained at 4.0 Torr, where the current densities 7.3x10 9 Am 2 and pinch radius 1.68mm.
