Abstract:
A formula for the electron thermal conductivity in a self-similar structure of magnetic islands, e.g. in the edge region of a stellarator equilibrium, has been derived for the collisionless limit. It is described by using the non-Gaussian process with fractal nature. We have shown that the electron thermal conductivity in the edge region is reduced, if magnetic islands are large enough.
