Description

An analysis technique of charge exchange neutral spectra is proposed and tested to obtain ion temperatures of a tokamak plasma. The technique models the deviation of the ion distribution from Maxwellian because of ripple trapped particles and introduces a hot ion effective temperature as a fitting parameter. The analysis code has been used to analyze active charge exchange data from TEXT discharges in which a significant up-down asymmetry in the neutral spectra was noted. An analysis considering ripple trapped particles removed some of the asymmetry and indicated the need for another mechanism for distorting charge exchange spectra
