Plasma recombination phenomena were observed in the interactions of hydrogen or hydrocarbon gasses with low temperature helium plasma stream along the longitudinal magnetic field, which simulated the divertor region. The reduction of the ion saturation current implies the existence of molecular activated/assisted recombination (MAR) processes. The recombination efficiency is much stronger in the methane and ethane than in the hydrogen injection case, namely, He much less than H-2 much less than CH4 much less than C2H6. In order to clarify the dominant processes in the hydrocarbon-enhanced MAR phenomena, spectroscopy on the A(2)Delta-X(2)Pi band of CH radical was conducted. In the electron temperature lower than about 6 eV, the dominant dissociation and emission processes of the CH radicals have qualitatively been revealed to be related to their charge exchange with bulk ions, which can be followed by the dissociative recombination with electrons.
