Effect of spatial transport of resonant electrons on the wave absorption during low-hybrid current drive

Theoretical model which describes both redistribution of resonance electrons and absorption of low-hybrid (LH) waves at presence of anomalous space transfer is suggested in the experiments into current upkeep in tokamak plasma through LH waves. Quasidiffusion approximation (QA) was used to describe space transfer of resonance electrons. Calculation program, designed to solve QA equation system with corresponding boundary conditions, which allows to calculate source of particles, nonohmic current, SF power, consumed to heat electrons with regard to space transfer of the accelerated particle beam and to evaluate direct diffusion losses as well, is developed on the basis of the described model
