To satisfy the special requirement of the X-ray diagnosis instrument which needs long working distance and wide spectrum measurement in ICF, a new two-channel curved crystal spectrometer has been designed according to the reflecting geometry of convexity. The spectrometer diffracts X-ray by Si(111) and Qz(10—10) curved crystals with overlapping coverage of 0.30~0.65 nm, and the spectra are recorded by X-CCD detectors. The spectrometers has been applied to diagnostics with Shenguang-Ⅲ Prototype. Data analysis demonstrates that the spectra of experiment are accord with those of the theoretical simulation.
