Nonthermal tails of the electron distribution in hot plasmas with nonlocal transport

Summary form only given, as follows. Self-similar solution to the stationary electron Fokker-Planck equation in two angular harmonic approximation has been found in inhomogeneous plasma with a given input of energy flux. This solution corresponds to the constant ratio of the gradient length to the electron energy exchange mean free path and specific n/sub e/(T/sub e/)-dependence. The form of an electron distribution function has been found in terms of the collisionality parameter. A self-similar solution describes reduction in the number of bulk electrons and formation of the superthermal tail. Fokker-Planck simulations confirm formation of such a tail and demonstrate possibility of another power-like dependencies of the tail on velocity. It has been shown that the specific power dependence in the electron tail distribution depends on the explicit form of the n/sub e/(T/sub e/)- spatial profile.
