چکیده انگلیسی
The paper describes the use of PM-355 track detectors for studies of spatial structures and energies of pulsed plasma-proton streams generated by an RPI-IBIS accelerator, powered from a 30-kJ condenser bank. Measurements were performed for different operational modes depending on a delay between the gas injection and discharge initiation. To study a spatial structure of the plasma-proton streams we used an ion pinhole camera with PM-355 detectors, placed at the symmetry axis of the experimental chamber, at a distance of 22 cm from electrode ends. To record low-energy (not below 30 keV) protons we did not apply any filter. To select protons of higher energies we used additional absorption filters made of Al-foils of 0.75, 1.5 and 3.0 μm in thickness, which eliminated protons of energies below 125, 210 and 345 keV, respectively. The spatial structure of the proton beams was analyzed and their dependence on the initial gas conditions was investigated.
