Ion Cyclotron Parametric Turbulence And Anomalous Convective Transport Of The Inhomogeneous Plasma In Front Of The Fast Wave Antenna (Vol 28, 042304, 2021)

The theory of the ion cyclotron (IC) electrostatic parametric instabilities of the inhomogeneous plasma that are driven by the inhomogeneous electric field of the fast wave (FW) in front of FW antenna is developed. It is found that the spatial inhomogeneity of the parametric IC turbulence and of the drift turbulence is at the origin of the flows that transport a large part of FW power, deposited to the pedestal plasma, to the scrape-off layer and later to the divertor mostly along field lines.
