| Outline of Final Research Achievements |
Divertor is a essential part in fusion devices. Understanding of heat and particle transport to divertor from high temperature and density core plasma is an important issue in the fusion research. In this study, we conducted improvements of a plasma and neutral particle transport code, EMC3-EIRENE with comparison between the experimental data and the results of simulation with the code. We measured the heat and particle fluxes profiles on a divertor tile, and constructed 2-dimensional visible spectroscopy for measuring hydrogen and impurities behavior in divertor. The profiles change during plasma discharge. The simulation can reproduce basic profile, but that cannot reproduce modified profile. Additional data analysis suggest that the modification of the profile is caused by a modification of magnetic field lines structure. By the spectroscopy, we got the data related to impurities behaviors. We will try to reproduce the behaviors with the improved code.
