Azimuthal distribution of the high-energy α-particle flow on chamber walls in an axial-symmetrical tokamak

The efficiency of confining high-energy α-particles (thermonuclear reaction products) in an axial-symmetrical tokamak-reactor is considered. The amount and spatial distribution of the particles falling onto walls of the discharge chamber due to toroidal drift are determined. In specific calculations employed are the parameters of the T-20 tokamak. It has been shown that the toroidal drift in the facility does not cause any considerable escape of high-energy α-particles from plasma
