Abstract [en]

Absorption by trapped particles is supposed to seriously hinder current drive by Alfven waves. However, it is shown in this paper that the same effect is rather beneficial for the emergence of the radial electric field induced by these waves, which is important for creating and maintaining transport barriers in tokamaks.
