Abstract
Results are reported from an experimental study of the characteristics of the turbulent edge plasma in the L-2M stellarator. Extended coherent structures are observed to form in the poloidal direction. The poloidal coherence length of the fluctuations reaches 20 cm. The coherence of the fluctuations depends appreciably on the poloidal azimuth and is maximum along the outer edge, as is natural for unstable modes in a toroidal plasma.
