[8S.12] DYNAMIC OF ELECTRON BEAMS RESPONSIBLE FOR TYPE III SOLAR BURSTS FINE STRUCTURE

Recent observations and theoretical reasons point in favor of the fact that the source of type III solar bursts emission consists of some electron beams. Propagating along opened magnetic field lines these electrons are supposed to generate radiation observed. Conditions in solar corona gives us that the quasilinear time is much smaller than the time of particle flying-off. Using this fact the main equation describing propagation of N monoenergetic beams are obtained and their solution is found. Electrons generating and absorbing Langmuir waves move as a row of beam-plasma structures. As a result of "interaction" between beam-plasma structures a part of slow structure electrons absorbing plasma waves accelerates into fast ones that leads to have their shapes changed and fast structures accelerated.
