METHOD FOR CONDUCTING THERMONUCLEAR REACTION IN MAGNETIC FUSION REACTOR Russian patent published in 2003 - IPC

FIELD: controlled fusion; extracting fusion energy, generating three-dimensional neutron sources (for instance to recover nuclear wastes). SUBSTANCE: method involves irradiation of heavy particles of fuel pellets injected in reactor chamber wherein high pressure of working gas not lower than atmospheric pressure is maintained using laser pulses or beams for the purpose. In the process problems of production of hot plasma, maintenance of inertialess current, and monitoring of plasma-magnetic configuration are solved. Circuit arrangement of magnetic fusion reactor of proposed type enables directly placing the installation in steady state running dispensing with rather sophisticated standard scheme of organizing hot plasma (gas breakdown at low working gas pressure, preheating of plasma with ohmic current, and the like). Proposed reactor enables combining advantages of magnetic heat insulation and near-wall plasma confinement implemented by building up so-called high- pressure gas cushion at plasma boundary. Proposed method may be found useful for installations with magnetic field configuration of tokamak, stellarator, or adiabatic trap type. Near-wall plasma confinement used in tokamaks makes it possible to avoid dangerous instability of discharge failure. As rather high pressure (and density) of plasma can be maintained in proposed reactor (compared with traditional magnetic confinement of plasma), this reactor can be used for conducting fusion reactions at low section of reactions (for instance in case of D+He³ nuclei fusion reaction). EFFECT: enlarged functional capabilities. 1 cl, 1 dwg
