Karazin popup.description2 Subject of investigation is the interaction of high energy charged particles with steady state resonant magnetic perturbations (RMP) and high frequency electromagnetic field with the frequency in ion- cyclotron resonance range in plasma, which is confined in closed magnetic trap. Purpose of the work is to optimize the operation regime of fusion reactors with the help of improved theoretical model of the power and particle balance in non-Maxwellian plasmas. Analysis is theoretical. The numerical code is improved in order to simulate the impact of RMP on plasma dynamics by taking into consideration the real geometry of magnetic surfaces of modern fusion devices. The power and particle fluxes from plasmas are calculated as a result of statistical data analysis of the particle trajectories. The possibility of formation of non-Maxwellian distribution function of plasma particles due to ICRF heating is studied in details. It is demonstrated that the shape of the distribution function is crucial for fusion reactivity calculation. To simulate the interaction of the fast wave with plasma particles, the numerical Monte-Carlo operator was included in the numerical code. Numerical solution of the power and particle balance equations gives possibility to estimate the reduction of the ignition threshold and to obtain the optimized conditions for plasma burning in fusion reactors including the effect non-Maxwellian distribution function.
