Description

The anomalous diffusion of alpha particles (product of DT fusion) in a field of trapped-ion turbulence is considered. It is shown that allowance for the slight non-potential character of this mode considerably increases the diffusion coefficient. For the parameters of tokamak reactors currently being planned the diffusion coefficient is found to be two orders of magnitude greater than the electron diffusion coefficient. (author)
