Analysis of the radial profile of ion temperature in ICRF-heated GAMMA10 plasmas including the effects of ion finite Larmor radius

This paper describes a modified method of analysis of the charge exchange neutrals for determination of the radial profile of ion temperature including the effect of the ion finite Larmor radius. It also includes the effect of the charge exchange reaction with neutral hydrogen molecules. The ICRF-heated plasmas in the central cell of the GAMMA10 tandem mirror were analyzed by taking into account these effects. The obtained energy spectra and the count-rate spatial profiles of charge exchange neutrals were consistent with the experimental results. The present method, thus, proved to be effective in determining the radial profile of ion temperature. (author)
