Abstract

In this letter, we present direct evidence of eddy breaking and tilting events observed at the edge of the TEXTOR tokamak using a 2D gas puff imaging diagnostic. The occurrence of eddy breaking depends on the magnitude of the E _r×B flow shearing rate. The results confirm the theoretical predictions about the influence of E _r×B sheared flows in tilting and splitting turbulence eddies, and consequently, reducing the turbulent transport.
