In this study, numerical experiments on ion beam features emitted from nine Dense Plasma Focus devices were carried out using the Lee model code (version RADPFV5.16FIB). A simulation (numerical experiment) and connected fitting procedure of a total discharge current waveform was presented on the example of the PF-24 device, and summary data concerning simulations and fitting procedures for each device were presented. The full details of the ion beam properties as a function of pressure for the PF24 device were presented. The properties of deuterons such as flux, fluence, flux energy, fluence energy, current density, ion current, damage factor, and energy of deuterons versus pressure were computed and investigated. A comparison between the properties of deuterons computed at fitted pressure and at a pressure where the flux is the highest was presented and discussed according to equations on which the Lee model is based.
