“…The code was used to determine current and neutron yield limitation, investigate neutron saturation effect, investigate radiative collapse and obtain anomalous resistance data. The model then has been also enhanced and used to study ion beams emitted from plasma focus devices [16][17][18][19][20][21][22]. Using the Lee model code, numerical experiments for two devices: APF [23,24] and PF400 [25,26] operated with nitrogen gas were simulated by entering several parameters including: Bank parameters (capacitor bank C0, inductance L0, stray circuit resistance r0), Tube parameters (length z0 and radius a of the anode, the radius of the cathode b) and Operational parameters (operator charging voltage V0 and pressure P0 of the gas, the energy storage in the capacitor bank E0).…”
