摘要：
Inversion techniques are conducted based on the tangential x-ray crystal spectroscopy(TXCS)geometry on EAST to obtain the local profiles of ion temperature(Ti) and toroidal rotation velocity(vt). Firstly, local emissivity profiles of the impurity argon are obtained using the asymmetrical Abel inversion.Then, the local vtand Tiprofiles are calculated by considering the local emissivity profiles and the TXCS detailed geometry. In addition, how the changes in the vtprofiles affect the accuracy in the Tiprofiles is discussed in detail. It is also found that the lineintegrated Tiprofiles are becoming less accurate with the increase in the radial gradient in the local vtprofiles. Nonetheless, accurate Tiradial profiles are reconstructed after considering the effects of the emissivity and velocity, which are verified by comparing the inverted vtand Tiprofiles with those local profile measurements from the Charge eXchange Recombination Spectroscopy(CXRS) on EAST.
