Abstract

An advanced full f gyrokinetic three-dimensional (3-D) plasma simulation code has been developed, thus making it possible to treat steep plasma gradients, wide particle orbit effects, and rapid dynamic changes in long simulations. The study of a small tokamak plasma heated by lower hybrid waves shows a generation of internal transport barrier which is detected as a simultaneous collapse of heat and particle diffusion coefficients as well as large scale structures in fluctuations inside the barrier.
