METHOD OF PRODUCING HIGH-ENERGY PARTICLE STREAMS AND APPARATUS THEREFOR Russian patent published in 2015 - IPC H05H1/24 H05B7/18 

FIELD: chemistry.

SUBSTANCE: invention relates to plasma engineering and can be used in designing sources of high-intensity particle streams for scientific and engineering applications. The method of producing high-energy particle streams in gases comprises accelerating a heterogeneous stream in a de Laval nozzle. The method comprises feeding a plasma stream into the subsonic part of a de Laval nozzle, facilitating acceleration thereof to sound speed and full recombination of the plasma before the nozzle throat section and, after the nozzle throat section, feeding particles into the stream and accelerating the heterogeneous gas stream in the supersonic part of the de Laval nozzle. The apparatus for producing high-energy particle streams comprises a continuous plasma source, a de Laval nozzle and a particle input system. The apparatus further includes a high-pressure chamber, an array of N continuous microplasmatrons and a high-pressure gas supply system. The length of the subsonic part of the de Laval nozzle is defined by the condition for full recombination of the plasma before the nozzle throat section, and the particle input system provides input of particles after the nozzle throat section on the entire perimeter of the nozzle in the cross-section of the nozzle with given parameters - temperature and speed of the gas.

EFFECT: designing sources of high-intensity particle streams.
