Abstract

Here we report the results of the turbulence study in the high confinement mode (H-mode) with and without edge localized modes (ELMs). The study was performed by the Doppler backscattering (DBS) method on the Globus-M tokamak. It was demonstrated that the transition from the H-mode with ELMs to the ELM-free H-mode is characterized by the drop of the turbulence intensity near the periphery.
