Characteristics of the ion beams produced in a plasma focus device were studied. In the experiment, a Mather type plasma focus device was used and it was pre-filled with 2.3 Torr H2. The plasma focus device capacitor bank of 43.2 µF was charged to 30 kV to get a peak current of 350 kA. Ion spices and their energy spectrums were evaluated using a Thomson parabola spectrometer, and the particle pinhole image was obtained with an aluminum filtered particle pinhole camera. While, the ion current density was measured with a biased ion corrector. The proton beam energy was distributed from 0.15 MeV to 2 MeV. On the other hand, we found singly and multiply ionized ions of C, N,. The particle pinhole image of the proton beam, which has energy more than 1MeV, was spot type. The ion current density of 1200A/cm2 was obtained. The peak power brightness for the proton beams was 18 GW / cm2 / Sr /keV.
