Abstract

A tangential image of an H-alpha intensity profile in a large helical device (LHD) plasma is investigated by a neutral particle transport simulation using a detailed 3-D grid model including the geometry of the helical plasma and the vacuum vessel. The calculated image of the H-alpha intensity profile calculated by the simulation quite agrees with the observed image, which strongly suggests that there is no significant abnormal neutral particle sources in typical plasma discharge operation in LHD.
