Abstract

Experimental results showing evidence for the development of filaments in plasma of the Globus-M spherical tokamak have been obtained by the method of Doppler reflectometry. The correlation between the reflectometric data and results of probe measurements at the periphery of discharge in the tokamak is found. Experimental data were used to determine the rotation velocities of filaments, the moments of their appearance at the transition to improved confinement, and regions of filament formation.
