Abstract

The wave induced fluxes of energetic trapped ions during ICRF heating of tokamak plasmas are calculated by using quasi-linear equations. A simple single particle model of this transport mechanism is also given. Both a convective flux proportional to k_øE₊² and a diffusive flux proportional to are found. Here, k_ø is the toroidal wavenumber and E₊ is the left hand polarized wave field. The convective flux may become significant for large k_ø if the wave spectrum is asymmetric in k_øBut for k_øρ≪1, a condition satisfied in most previous and planned experiments, radial transport driven directly by the ICRF wave is unimportant.

N2 - The wave induced fluxes of energetic trapped ions during ICRF heating of tokamak plasmas are calculated by using quasi-linear equations. A simple single particle model of this transport mechanism is also given. Both a convective flux proportional to køE+2 and a diffusive flux proportional to are found. Here, kø is the toroidal wavenumber and E+ is the left hand polarized wave field. The convective flux may become significant for large kø if the wave spectrum is asymmetric in køBut for køρ≪1, a condition satisfied in most previous and planned experiments, radial transport driven directly by the ICRF wave is unimportant.
