 NANO POWDER, NANO CERAMICS, LUMINESCENCE, SPRAYING, TUNGSTEN, METAL HYDRIDE CATHODE. Research objects: nanostructured ceramics, nanopowders of dielectric materials; carbon to interact with ions; spraying systems; as well as the principles of metal hydride activation of hydrogen. The goal of the project is to establish the patterns of luminescence depending on the luminescence spectra of nanostructured ceramics on the conditions of its sintering, the study of sputtering of metals to create new functional coatings, the study of tungsten degradation under the powerful action of plasma flows, the effective extraction of H– ions from a Penning discharge with a metal hydride cathode across a magnetic field. New methods of creating new materials with given properties and testing existing ones will be researched and developed. The effect of the sintering temperature of nanostructured materials on their optical properties is indicated. Intensification of magnetron discharge parameters based on a standard MAG-5 type magnetron sputtering system (MSS) with near-anode magnetic trap is demonstrated. The rate of degradation of tungsten under the action of stationary and pulsed plasma flows with parameters close to those in ITER is shown. It is shown that in a device with a metal hydride cathode, H– desorption occurs across the magnetic field.
