Abstract

Comparisons are made between EDGE2D-EIRENE simulations that use a new CHEM database for He II with the existing ADAS database. This allows lower simulated electron temperatures to be reached (~2 eV) close to the divert or target plates. At temperatures of ~ 2 eV in He (~ 1 eV in D) intense recombination-driven radiation becomes important. This study shows the importance of the highest quality atomic data in edge transport modelling.
