Recent ECRH Experiments in the L-2 M Stellarator with the Use of a New High-Power Gyrotron

The results of experiments on plasma confinement at ECRH power density up to 1.5 MW/m3 are reported. It is shown that the results of measurements of the diamagnetism and poloidal rotation velocity of the plasma in the peripheral region agree with numerical calculations using a neoclassical model with allowance for anomalous losses. The correlation has been found between the low-frequency modulation of the gyrotron power radiation and the modulation of the radiation scattered by the turbulent plasma density fluctuations.
