High power Alfven Wave Heating, applied to the TCA Tokamak, results in an electron and ion temperature increase, together with a plasma density rise. The various terms leading to an ion temperature increase are investigated to determine whether any of the applied RF energy is absorbed directly by the ions. This is done by a detailed comparison with non stationary ohmic discharges. It is concluded that although a large fraction of the ion temperature increase may be assigned to the density increase, there remains a component that is most simply described by direct ion heating.
