- Abstract
The results of a study of toroidal Alfvén modes using the multifrequency method of Doppler backscattering at the Globus-M tokamak have been presented. The method for recording Alfvén modes in multichannel probing has been introduced. The possible causes of the observed oscillations of the poloidal velocity of plasma rotation at the frequencies of Alfvén waves have been discussed in detail. The data on the spatial distribution of Alfvén modes have been presented. The recommendations for further development of Doppler backscattering for a more detailed study of toroidal Alfvén modes at tokamaks have been defined.
