Abstract

The He I optical emission spectroscopy that considers the spatial structure of radiation trapping was proposed by us and was applied to a MAP-II divertor simulator. The spatial distribution of the optical escape factor was calculated from the n (1)P (n≥3) state profiles measured by visible spectroscopy. The profile of 2 (1)P, which is immeasurable by visible spectroscopy, needs to be broader than that of the 3 (1)P state. The sensitivity of the 2 (1)P profile to the T(e) value estimated by He I spectroscopy is investigated.
