The elliptical bent crystal spectrometer (EBCS) is coupled to X-ray CCD, and a set of system called focusing spectrometer has been developed. Optimization calculation indicates that the EBCS will allow a large measuring spectral range (0.133～0.756 nm) with crystals of practical dimensions and for a working distance of 981.56 mm to the source and have a spectral resolving power (λ/Δλ) better than 1000 as well as high signal-noise-ratio. X-ray spectrum from the laser-produced plasma has first been measured by the EBCS in the “ShenGuang Ⅱ” Facility. Some ion-like spectral lines were identified and classified. The measured energy resolution of spectrograph was also given. Such emission of resonance line, satellite line inter-combination line of like ions, and Lyman alpha line is useful for establishing the spatial distribution of electron temperature and ions density maps.
