P-12 · Condition of damping of anomalous radial transport, determined by ordered convective electron dynamicsMaslov, Vasilij1) Abstract Anomalous plasma particle transport due to low-frequency perturbations in the crossfield edge region of the toroidal devices is investigated now intensively. In turbulence of small amplitudes the electron trajectories are stochastic. At achievement of the large amplitudes when frequency, Ω, of the electron oscullations in the convective cell of the perturbation exceeds the growth rate of its excitation, Ω(t)>γ, the cell changes in its vicinity the electron density gradient, which strengthens the next cells. Thus on the cell bounderies the jumps of ne(r) arise. On these jumps the growth rates of the next cell excitation are much more than the growth rate, determined by not perturbed. It provides faster electron transport. In other words, the selfconsistent excitation of the low-frequency convective cells in the nonequilibrium plasma, drifting in crossed electric and magnetic fields in stelarator, by a radial gradient of density is unstable concerning occurrence of correlations.
