FIELD: electricity; physics.
SUBSTANCE: invention relates to a source of intense wide-aperture (up to hundreds cm) plasma streams with high degree of ionisation with effective current of hundreds of amperes. Device can be used in high-current sources of ions, in microelectronics, nuclear physics and in a number of other plasma technologies. To create plasma in magnetic trap under conditions of electron-cyclotron resonance powerful electromagnetic radiation of millimeter range of waves is used. In the source of plasma flows, the gas feed system is made in the form of a multi-aperture system of tubes with independent supply of working gas. Besides, there is an additional magnetic coil limiting the transverse dimension of the plasma expanding from the trap.
EFFECT: technical result is possibility to control transverse distribution of gas flow and to form wide-aperture flow of plasma with necessary, including flat, transverse structure, which increases density of gas-discharge plasma.
