The influence of the transport of fast charged particles in burning fusion targets

Abstract: For an adequate description of the physics of laser plasma it is necessary to consider a large number of physical processes. One of them is the transfer of energy of a fast particle products of thermonuclear reactions. The problem of the birth and transfer of the charged particles resulting from fusion reactions in a burning deuterium-tritium plasma, is very significant. It is important to reflect in the model, where and how charged particles give up their energy, i.e. to calculate the non-stationary transfer of energy of the fast charged particles. The paper presents a model calculation of the transport of α-particles, we numerically investigate the influence of this process on the parameters of the target.Note: Research direction:Mathematical problems and theory of numerical method

Numerical simulation of the electron heat transport in a collisional plasma by finite difference method

Abstract: An algorithm for the numerical solution of the plasma kinetic equation in 1D2V geometry is suggested. The nonlinear collision operator is computed on the base of the completely conservative difference scheme. Self consistent electrical field is computed from the condition of quasi neutrality at each time step. The numerical results for the relaxation of the initial temperature perturbation in a collisional plasma in 1D2V geometry are presented.Note: Research direction:Mathematical modelling in actual problems of science and technic
