Abstract

In this paper, an attempt is made to clarify some general aspects of the Alfvén current drive problem for magnetic traps. For large aspect ratio tokamaks, with an elongated cross-section, some general formulas concerning the untrapped particles dynamics and their input to the Landau damping of the Alfvén waves are presented. They are supposed to be used for the further development of the Alfvén current drive theory for tokamaks.
