Studying the behavior of oxygen and carbon impurities in the volume of content in the B-3M installation and flow sources of metallic impurities from the surface of the walls and the RF antenna. Research on high-frequency vacuum processing surfaces in the U-2M using continuous low bearing-down RF generators. During the implementation of this plan in both plants was significantly expanded diagnostic base for plasma research: established a multi-channel system for studying the plasma radiation in the visible region and in the soft X-ray, launched a new system of measurement of the plasma density, significantly improved circuits measuring electric and magnetic probes and pressure measurement working gas. This ensured the successful implementation of a pilot program of studies for two experimental campaigns (summer in the U-2M, and fall on the U-3M). Additional data were obtained on the plasma characteristics at different stages of HF discharge, including the start. This will allow a deeper discharge of features present in closed magnetic traps using HF moschnosti.Sredi important results it should be noted the following: After spending the first vimiryannya plasma B-2M using the method of heavy ions; The plant "Uragan-3M" found strong vertical asymmetry of the electron temperature in the divertor flows, indicating the presence of direct (nedifuziynih) loss of electrons from the plasma confinement volume due to magnetic field inhomogeneity. This result is important for the development of a fusion reactor schemes based on the stellarator concept;Proposed and experimentally tested a new method of preparation of the internal surfaces of thermonuclear devices. The technique uses an ultra-high frequency discharge at a high pressure of neutral gas and does not require the imposition of a permanent magnetic field; On the U-3M to study the structure of the MHD plasma oscillations and identified their influence on plasma confinement with a low frequency of collisions.
