| Abstract: | This paper describes the elliptical crystal spectrograph(ECS) which is used to investigate X-ray spectroscopy of laser-produced plasmas. The spectrometer was calibrated for experiments on “Shenguang Ⅱ” X laser target chamber. The K-shell and M-shell emission lines of laser-produced plasma were measured by the space-resolved spectrometer. Some X-ray spectral lines were obtained through studying and classifying photographs of spectra recorded by X-ray CCD camera. The measured spectral resolution of spectrograph was given. The focusing spectrometer based on the ECS provides high spectral resolution and spatial resolution as well as high luminosity(high collection efficiency). Possible applications of the ECS are demonstrated. |
