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