Research Abstract

Detached deuterium recombining plasma has been generated in the toroidal divertor simulator. The electron temperature (0.1-0.4eV) and density (~10^<18> m^<-3>) in the detached plasmas were evaluated with a spectroscopic method using a series of deuterium Balmer line emission from highly excited levels and the Stark broadening of D(2-12). We have investigated the role of volume plasma recombination through Electron-Ion Recombination (EIR) and Molecular Activated Recombination (MAR) processes. Moreover, the carbon erosion in the detached deuterium plasma has been studied with a weight- loss method. It is found that deuterium neutrals generated by EIR process could have a strong influence on the carbon chemical erosion.
