Abstract
We report the observation of a key feature of intermittency in the tokamak edge turbulence. The probability distribution functions of broadband plasma density and potential fluctuations in an Ohmically heated tokamak plasma are measured and shown to be non-Gaussian. The intermittency is observed on scales large compared to the dissipation scale and it is found to evolve during the flattop current phase of the discharge.Keywords
