چکیده انگلیسی
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 30Â kV/44Â kJ, 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 2Ã1012ions/cm2 at a distance of 30Â cm from the electrodes outlet. Energy spectra of protons and deuterons ranged from about 30Â keV to about 400Â keV. The ion distributions, as recorded by means of the PM-355 and LR 115A detectors, are similar.
