Inversion techniques to obtain local rotation velocity and ion temperature profiles for the x-ray crystal spectrometer on EAST

Inversion techniques are conducted based on the tangential x-ray crystal spectroscopy(TXCS)geometry on EAST to obtain the local profiles of ion temperature(T_i) and toroidal rotation velocity(vt). Firstly, local emissivity profiles of the impurity argon are obtained using the asymmetrical Abel inversion.Then, the local vtand T_i profiles are calculated by considering the local emissivity profiles and the TXCS detailed geometry. In addition, how the changes in the v_t
