A two-crystal spectrometer system has been implemented in the EAST tokamak to simultaneously measure high- and low-temperature plasma regions using He- and H-like Argon spectra. But for future devices like ITER and CFETR, the Ar ions become fully stripped and the intensity of the H-like lines weaken significantly at high temperatures (Te>5 keV). With increasing auxiliary heating power on EAST, the core plasma temperature could also reach 5 keV and higher. In such conditions, the use of a Xenon puff becomes an appropriate choice for both ion-temperature and flow-velocity measurements. A new two-crystal system using a He-like Ar crystal (2d=4.913 Å) and a Ne-like Xe crystal (2d=6.686 Å) has been deployed on a poloidal XCS spectrometer. While the He-like Argon spectra will be used to measure the plasma temperature in the edge plasma region, the Ne-like Xenon spectra will be used for measurement in the hot core. The new crystal arrangement allows a wide temperature measurement ranging from 0.5 to 10 keV or even higher, being the firsts tests for burning plasmas like ITER and CFETR. Preliminary result of lab-tests, Ne-like Xenon lines measurement and a new calibration procedure using a Ti x-ray tube will be presented.
