Description
Electron temperature and density of a hydrogen plasma are measured using laser Thomson scattering in divertor simulator MAP-II. Population of hydrogen atom calculated using the temperature and density are compared to that obtained from Balmer series emission spectroscopy, showing molecular assisted recombinations (MAR) contribute to populating process. One of the MAR, mutual neutralization following negative ion production is indicated by increase of p=3 excited state, while dissociative recombination of molecular ion (H2+) increases p=4-6 states
