Non-Maxwellian ion distributions caused by neoclassical heat conduction
Journal Article

· Phys. Rev. Lett.; (United States)
It is shown that in tokamaks with neoclassical banana-regime heat conduction and ion self-collisions dominant for energy scattering, the distribution tail diffuses outwards radially and downwards in energy maintaining a constant effective temperature (-partial lnf/sub i//partialepsilon)/sup -1/, as observed in some experiments.
