Three-dimensional particle-in-cell simulations of gap crossings in castellated plasma-facing components in tokamaks
Original language description
This paper presents first 3D particle-in-cell simulations of castellated plasma- facing components (PFCs) in tokamaks. Special focus is given to crossings between poloidal and toroidal gaps where elevated heat loads are expected to occur. Localized heatloads can potentially lead to a damage of the tiles. This paper presents results of a full 3D3V code SPICE3, which allows to simulate a more realistic geometry of the tiles including the gap crossings and includes the complete ExB drift, which could notbe simulated in 2D. The results of self-consistent simulations show that the crossing acts as a transport channel for electrons, allowing them to enter the plasma shadowed region in poloidal gaps. As a consequence, the potential near the gap entrance ismodified allowing more ions to flow deep i pard
