Description
High-resolution Hα line contour has been measured with optical spectroscopy multichannel analyzer (OSMA). The energy distribution of neutral hydrogen atom has been derived from the Hα line contour, which shows that the main process of the particles at the edge of plasma is the reflection of the ions neutralized at the surface of the limiter, the excited and ionized dissociation of the hydrogen molecule by electron impact. The incident velocity of recycling particle has been given with Gaussian fitting
