To diagnose the gas-puff pinch plasma at wavelength range from 0.3 to 0.5 nm, a space-resolved curved crystal spectrometer has been developed based on Mica(002) crystal with Bragg angel of 37°. In experiments carried out on the Yang accelerator, X-ray spectra in an absolute intensity scale were obtained from argon gas-puff pinch plasmas, which were recorded by a 30 mm×80 mm flat film. The measured wavelength was consistent with the theoretical value, and the He-like spectral resolution was 200 to 300 for the mica crystal spectrometer, showing its potential in the analysis of X-ray emission from a gas-puff pinch plasmas source.
