We report on recent advancements of the synthetic diagnostic module in the post processing part of the 3D kinetic (neutral particle) transport code EIRENE (www.eirene.de). We also review and upgrade the underlying atomic helium data base, resorting to the most recent version of the Goto-Fujimoto collisional radiative helium code and a recommended reference cross section data set from an internationally coordinated (IAEA) evaluation activity. Using both the upgraded transport code and data base, we then simulate the penetration of and radiation from helium used for beam emission spectroscopy, exemplarily for the configurational set up at the Wendelstein 7-X stellarator. This allows to analyse and evaluate the application of the diagnostic in different plasma backgrounds and with different atomic models. We simulate fully 3D resolved edge plasma backgrounds with the fluid edge plasma Monte Carlo code in three dimensions (EMC3) coupled to EIRENE. The sensitivity of the entire diagnostic concept to the underlying atomic data set, which is the key for a quantitative determination of electron density and temperature profiles, is discussed |
