Development of a non-linear rf sheath benchmark suite*

The Bohm sheath on plasma facing components (PFCs) can be energized through rectification by RF waves that reflect off of the PFCs. This can create voltages in excess of 100 V that are sufficient to cause impurities to sputter the surface. The modeling of this effect is a very active area of research. In this poster we present cases that have been benchmarked across several codes using different approaches. Many of these cases were first shown in Kohno Comp. Phys. Comm. (2017). We demonstrate consistency of the solution to high accuracy independent of approach. Cases include non-linear sheaths in 1D and 2D and the sheath plasma wave. These cases should serve as a benchmark suite for developers.
