Schematic image of turbulence suppression (IMAGE) National Institutes of Natural Sciences Caption A schematic image of trapped electron instability and the mechanism for the suppression of turbulence in deuterium plasma. When ion mass is larger, instabilities are reduced and the zonal flow increases, and the loss of heat and particles in the plasma is suppressed.
