摘要：

The profile of absolute carbon ion density is calculated based on the charge exchange recombination spectroscopy (CXRS) diagnostic on HL-2A tokamak. The carbon ion concentration is derived by a combination of absolutely calibrated active spectrum intensity, neutral beam densities and effective charge exchange emission rates. The neutral beam densities for the full (E-b), one-half (E-b/2) and one-third (E-b/3) fractional beam energy components are calculated with the beam attenuation process which is determined by the beam stopping cross-section. The beam population of H*( n = 2) to H(1 s) is evaluated, both of which contribute to the charge exchange procedure as donors. Z(eff) profiles measured by the local impurity concentration and visible bremsstrahlung are compared. (C) 2020 The Japan Society of Plasma Science and Nuclear Fusion Research
