The purpose of this work is to study the effect of multi‐step ionization on the tokamak scrape‐of layer (SOL). Using particle‐in‐cell (PIC) simulations we show that this effect strongly influences the divertor plasma. Our results suggest that, at least for high‐recycling regimes, multi‐step ionization should necessarily be included in SOL analysis. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
