The current driven by means of EC waves, so-called Electron Cyclotron Current Drive (ECCD), has been proposed as a tool | |||
for non-inductive current induction in tokamaks, as well as a mean of current control and tailoring of the rotational transform in stellarators. | |||
In particular, it can modify through its impact in <math>\iota</math> the map of Alfvén eigenmode, and consequently those that a | |||
free energy source can excite and modify the fast ion dynamics. | |||
In view of future studies of AE-induced fast ion losses in TJ-II the present proposal focuses on the validation of the | |||
ECCD predictions comparing these with the experimental values. | |||
