| Abstract: | The ion beam of a Mather-type 23.25 J plasma focus device operated with air filling at 10 Torr was registered using CR-39
nuclear track detector. The irradiated samples were etched in NaOH solution at 70°C for 1 h. It is found here that plasm a
beam contains multi-components of microbeams. The individual track density of microbeams is estimated and the total current
density of the plasma stream is measured to be 1.2 mA/cm2. A model for counting the track density of individual microbeams is proposed here. Faraday cup measurements showed the ion
pulse with energy ranging from 5.8 keV to 3.3 keV.
