WallDYN simulations of material migration and fuel retention in ITER low power H plasmas and high power neon-seeded DT plasmas
A. Khan,G. De Temmerman,S.W. Lisgo,Xavier Bonnin,H. Anand,M.A. Miller,R.A. Pitts,Karl Schmid,A.S. Kukushkin +8 more
TL;DR: In this article, the 2D SOLPS numerical grid does not extend all the way to the wall surfaces so that an extrapolation of the plasma background is required and is performed using a second simulation stage in which the far scrape-off layer (SOL) region is numerically gridded and plasma transport is solved on the extended grid using the 1D simplified Braginski code.
