Experimental data indicating the influence of the magnetohydrodynamic tearing mode in the Globus-M spherical tokamak on the appearance of filamentary structures (filaments) are presented. The filaments were detected by the Doppler backscattering method. Filament groups localized in the toroidal direction were detected, the appearance of which turned out to be synchronized with the spreading of the tearing mode. The possible causes of the influence of low-frequency MHD oscillations on the occurrence of groups of filamentary perturbations are considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
