Interaction between filaments and ICRF in the plasma edge

Ion Cyclotron Range of Frequencies (ICRF) heating is a standard heating method for magnetic confinement fusion devices. ICRF waves can interact with filaments in the scrape-off layer (SOL) and induces a series of important phenomena. Understanding their interaction and the related physics is essential to the success of ICRF heating and plasma confinement. This paper is a review paper summarizing the recent progress in understanding of interaction between filaments and ICRF in the plasma edge and presents some key experimental and simulation results. In particular, the influence of RF convective cells on filament transport and the influence of filament on RF wave scattering, energy spectrum density, power redirection and wave mode conversion are discussed in detail. Most results shown in the paper make use of the published work, and some new results about mode conversion are also present.
