EFFECTOFDUSTPARTICLEON CHARACTERISTIC OF EDGE FUSION PLASMA

Abstract

In this workeffectofdustparticleon characteristic of edge fusion plasmais investi- gated. The given mathematic model, where the dust particle is heating by the fluxes of electrons and ions, their recombination on its surface, emission processes and are cooling by radiation and evapo- ration. The energy fluxes to the dust particle and recombination power energy by the dust particles are obtained. It is shown that the injection of dust particles, due to the interaction of the plasma with the wall of the fusion reactor, leads to a loss of energy of the plasma column and reduction of the positive energy yield of thermonuclear reactions.

Keywords: thermonuclear reactor, edge plasma, dust particle, thermal radiation, emission's processes.
