Abstract
We analyzed the energy balance of a fusion system based on an axially symmetrical open trap. In the considered system, the injection of high-energy (fast) particles is the main source of plasma external heating. Simulation of physical kinetics of the injected particles is based on the numerical solution of the Fokker-Planck equation taking into account scattering into the domain of losses and participation in the fusion reactions. Despite the considerable energy losses of the injected particles when leaving the trap due to the angular scattering, the considered system is sufficiently effective to be used as a source of neutrals for the hybrid (fusion-fission) reactor. The principle possibility of achieving a power amplification of Q pl ≈ 1 in plasma was demonstrated in operation modes with high neutron yield.
