Pan'kin O. Turbulence of non-equilibrium plasma near the boundary of marginal stability

Study of the turbulence of ITG driven modes near the boundary of marginal stability is carried out on the basis of analytical methods of mathematical physics and numerical modelling. The work aims to identify the mechanisms of the turbulence. The modified explosive instability (MEI) is considered for the explanation of the turbulence of nonequilibrium plasma near the boundary of marginal stability. Coherent structures, which arise during self-saturation of MEI, were found for the first time. The results are used for an explanation of the experiments on coherent structures in the tokamak plasma. The applications are connected with an explanation of behaviour of nonequilibrium plasma near the boundary of marginal stability. The scope of use is covered the physics of plasma and controlled nuclear fusion.
