The Measurements of Ion Temperature in the HL-2A Tokamak with CXRS

In the large and medium-sized tokamak,charge exchange recombination spectroscopy(CXRS) diagnostic is a very effective diagnostic tool after injecting neutral particles into the tokamak.It can be used for the measurement of plasma rotational velocity,ion temperature and other important parameters.By the effective experimental data analysis of the Southwest Institute of Nuclear Physics,the ion temperature of shot number 10419-track 4 which is close to the core is about 400 eV;the central ion temperature in shot number 10419-track 6 is about 700 eV.
