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 ø |E + | 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 ø . But for k ø ρ≪1, a condition satisfied in most previous and planned experiments, radial transport driven directly by the ICRF wave is unimportant.
