Fast ions have been found to impact plasma confinement [1]. Understanding the underlying physics is an essential task for future fusion reactors where plasmas will be dominated by fast particle dynamics. In particular, non-linear excitations of zonal structures by fast particle driven modes are predicted to play an important role on the nonlinear dynamics of AEs and related transport [2]. The goal of the proposal is searching for zonal fields (i.e. magnetic fields) and zonal flows (i.e. radial electric fields) driven by fast particles in TJ-II.
