Abstract

The gas composition ratio inthe divertor region of a fusion reactor must be measured in order to evaluate its atomic-molecular processes precisely. In this research we propose a method to measure the gas composition ratio of He, H and H2 of the H-He mixture plasmas in divertor simulator MAP-II by using passive spectroscopy of the Balmer series of hydrogen atoms, the Fulcher-α band of hydrogen molecules and the He I emissions.
