Abstract
The structure and main characteristics of ECE complex on T-10 are presented. T-10 ECE system possesses by certain features: measurements are fulfilled simultaneous on 1st and 2nd harmonics; frequency range of every harmonic is widened down; ECE measurements are made in two polarization at the same time; antenna system has narrow angle diagram that permits to discover several dynamic and structure peculiarities of global plasma oscillations in m/n=1/1 mode; ECE equipment is used also for measurement of emission in frequency range of magnetized Langmuir oscillations. Some results of measurements are shown: an unevenness of disturbances motion in space; appearance of rational magnetic surface on half of q=1 surface radius; strong oscillations of longitudinal electron velocity at the central plasma area; stability of distribution function of high energy electrons at plasma edge; spectrum of plasma oscillations in sawtooth regime.
