Abstract
The measurement of D, CII and CIII line spectral profiles and the CD band spectrum from the vicinity of a test limiter surface is performed in Heliotron J test limiter experiments. With deep insertion of the limiter, there is a localized intense region of the D, CII and CIII line intensity in the limiter surface, and the CD band spectrum is observed at this region. It is considered that the deuterium ion flux and heat load concentrate at this region and enhance carbon impurity generation.r_che
