摘要：

Recent results of the electric field potential profiles and plasma turbulence study and HIBP diagnostics development in TJ-II are presented in this work. As a rule, increase in plasma energy confinement is associated with the negative electric field formation, turbulence suppression and rise of the plasma density. Recently in the experiments with ECRH power modulation was found that the amplitude of the potential modulation Delta phi is a function of plasma density and potential phi depends non-linearly on n(e) with a critical value n(crit) approximate to 0.67x10(19) m(-3). The new observations of fast particle generated quasicoherent modes were observed along with conventional Alfven Eigenmodes. There are several new types of the NBI induced modes found, which presents non-Alfvenic frequency dependence from plasma density, f(AE) similar to n(-1/2).
