Abstract

In this paper, the results of an experimental investigation of dust formation in a pulsed plasma accelerator, which is formed due to the interaction of a pulsed plasma flow with the candidate material of the thermonuclear reactor, are presented. Dynamic and optical properties of a pulsed plasma flow are considered. The results of the synergetic analysis by the Raman spectrometer of the target surface after irradiation with plasma are also presented. It was revealed that after interaction with the plasma, the surface of the graphite target becomes amorphous. Materials with fractal surfaces, similar to the materials formed in tokamaks under the action of erosion, were obtained experimentally. Using a high-speed camera Phantom v2512 video shooting of the plasma beam was carried out, during which it was revealed that the pulsed plasma beam has a speed of about 23 km/s.
