In proposed Tokamak RF heating schemes using waves near the lower hybrid frequency, fields with large k_⊥a_i can be generated, either directly by linear conversion into lower hybrid waves or by the parametric decay into lower hybrid waves and ion Bernstein waves. The fields can significantly perturb the motion of an ion, and hence can nonlinearly heat the ions. In this report we present the results of a numerical solution of the orbit equation and give an approximate formula for the ion energy gain.
