EDGE PEDESTAL

STRUCTURE AND TRANSPORT

Fusion Research Center
 

A signature feature of high confinement (H-mode) tokamak plasmas is the formation of an edge pedestal region in which steep gradients in the density and temperature and wells in the radial electric field and rotation velocity are observed.  The structure of and transport in this edge pedestal has been a focus of collaborative research involving Georgia Tech and General Atomics members of the National DIII-D Team.
