Description
Radio-frequency current drive in tokamak plasmas in the presence of trapped electrons is investigated. The appropriate response function, allowing to express the current drive efficiency J/P by a simple analytical formula, is evaluated. It is shown that a significant degradation of the current generated away from the plasma axis is to be expected for methods relying on perpendicular diffusion only, even for appreciably large resonant parallel velocities.
