Sensitivity of scrape-off layer codes to modelling approaches
The study of plasma exhaust remains a core focus of current efforts towards viable DEMO-class magnetically confined fusion devices. The scrape-off layer (SOL) features complex physics. This is especially true for detachment, a mechanism where a cloud of neutrals forms at the divertor target and becomes a sink of plasma energy, momentum and particles through atomic and molecular processes. Edge plasma physics inherently necessitates modelling assumptions, and is often investigated using complex, computationally intensive 2D and 3D codes
