Abstract:
Electron temperature and density are measured, and the hot electrons in a plasma are investigated using the He I line intensity ratios in the NAGDIS-I linear device (Nagoya University Divertor Simulator)[S. Masuzaki, and S. Takamura, Jpn. J. Appl. Phys. 29, 2835, (1990).]. He I line intensity ratios have been calculated with the collisional radiative model using new atomic data allowing for the presence of hot electrons, and summarized for the electron temperature and density measurements especially for the edge or divertor plasmas in the fusion device.
