<p>The invention relates to plasma engineering, in particular to means for generating plasma using microwave fields and can be used in power engineering for burning any types of fuels, in plasma chemistry for decomposing and synthesizing chemical agents, in space engineering as maneuvering jet engines as well as for cutting and melting materials. The inventive UHF plasmotron comprises a magnetron (1) and a cylindrical resonator (3) divided, by means of a gasproof dielectric partition (6), into an input chamber (7) with the antenna (2) of the magnetron (1) arranged therein and an output chamber (8) which is provided with an orifice (4) with a nozzle (5) and is connected to a system for supplying a plasma-forming gas. The invention is characterised in that a second dielectric partition (9) with an orifice (10) in the center thereof is disposed in the output chamber (8) and in that a cavity between the partitions (6) and (9) is coupled to the system for supplying a plasma-forming gas (11). The inventive structural design of the UHF plasmotron makes it possible to efficiently cooling the dielectric partition of the resonator, to reduce the temperature of the walls and the nozzle and to stabilise a UHF discharge, thereby increasing the reliability and efficiency of the UHF plasmotron.</p> |
