Numerical studies of the imaging properties of doubly focussing crystals and their application to ITER. Doppler-Broadening Measurements of X-Ray Lines for Determination of the Ion Temperature in Tokamak Plasmas. Key words: Plasma diagnostic, Crystal spectrometers, Double crystal, Doppler broadening Conclusion: The application of double-crystal for X-ray curved-crystal spectrometers on EAST proposed in this paper is applicable and feasible. Results: Experimental results on the double-crystal X-ray spectrometer showed that the He-like and H-like Ar spectra were obtained for the first time, and the ion Ar temperatures calculated by two kinds of spectra were in good consistence within a certain error range. Consideration and technology route of the double-crystal were described and analyzed together with the experimental tests on the Experimental Advanced Superconducting Tokamak (EAST). Methods: The two crystals of the assembly having the similar Bragg angles were installed on the same pedestal, which could make the spectra recorded on the same detector. Purpose: This study aims to effectively broaden the temperature range of the spectrometers, an assembly of double-crystal was designed to replace the previous of single-crystal.
Background: X-ray curved-crystal spectrometer, as one of important diagnostic tool for measuring the plasma temperature and rotation velocity of the tokamak, is usually based on the satellite spectra of some special kind of impurity by single-crystal diffraction, which limits the temperature range to be measured simultaneously.
