Molecules in Detached Divertor Plasmas

In summary, for study of the detached divertor plasma, more exact measurements of the plasma parameter distributions are required. A Monte Carlo transport code treating the vibrationally excited molecules as distinct particles has been developed for analysis of molecular behavior in the detached divertor plasma, since vibrational excitation becomes important in such low-temperature plasmas. Requirements for molecular data are increasing to facilitate such analysis. Since the rates for the vibrational excitation are different between the hydrogen isotope molecules, data for molecules including deuterium and tritium are especially required. 

The investigation of molecular behavior in the divertor plasmas is important for establishment of heat and particle control in the tokamak. For attached divertor plasmas, where the electron temperature is high and the molecules
