Abstract
A gyrokinetic neoclassical solution for a diverted tokamak edge plasma has been
obtained for the first time using the massively parallel Jaguar XT3 computer at Oak Ridge National
Laboratory. The solutions show similar characteristics to the experimental observations: electric
potential is positive in the scrape-off layer and negative in the H-mode layer, and the parallel
rotation is positive in the scrape-off layer and at the inside boundary of the H-mode layer.
However, the solution also makes a new physical discovery that there is a strong ExB convective
flow in the scrape-off plasma. A general introduction to the edge simulation problem is also
presented.
