摘要

In this study, the flux and energy of the helium ions beam produced by United Nations University/International Centre for Theoretical Physics Plasma Fusion Facility (UNU/ICTP PFF) and NX2 dense plasma focus devices, were studied when the pressure of gas changed by carrying out numerical experiments using Lee code. The results showed that the value of the ions beam flux increased with increasing the gas pressure until reaching a maximum value 1.463E+28 ions. m-2s-1 at 7 Torr in UNU/ICTP PFF device while in NX2 device the maximum value is 6.442E+27 ions. m-2s-1 at 14 Torr and then decreasing while continuing pressure increasing, but the energy of ions beam showed the opposite behavior where the maximum value of energy of the helium ions beam was 13 Joul at 5 Torr in UNU/ICTP PFF device while it was 144 Joul at 14 Torr in NX2 device this is due to the effect of the geometric dimensions on the value of the induced voltage within the plasma pinch.
