The paper reports on measurements of pulsed plasma-ion streams, as performed with the selected solid-state nuclear track detectors (SSNTD). The ion-beams were produced by an experimental device (RPI-IBIS) equipped with coaxial electrodes (each made of molybdenum rods) and a fast-acting gas valve. The device was operated at 30kV/44kJ, with puffing of pure hydrogen or deuterium. The spatial structure of the ion beams was studied with pinhole cameras equipped with replaceable detectors, and ion mass- and energy-spectra were measured with a Thomson spectrometer. To analyse low-energy ions (below the energy thresholds of LR 115A and PM-355 SSNTD) an additional accelerating system was applied. It was observed that ions of energy >30keV are emitted in bunches, and the ion flux amounts to 2×1012ions/cm2 at a distance of 30cm from the electrodes outlet. Energy spectra of protons and deuterons ranged from about 30keV to about 400keV. The ion distributions, as recorded by means of the PM-355 and LR 115A detectors, are similar.
