Abstract

Abstract

For the research of X-ray spectrum of Z-pinch plasma, a wide variety of X-ray and extreme ultraviolet diagnostics are being developed to study on Yang accelerator. An elliptical curved crystal spectrometer was designed and the spectrograph has 1 350 mm focal length and for these measurements, a mica crystal bent onto an elliptical substrate was utilized with an eccentricity e=0.948 5. The crystal analyzer covers the Bragg angel ranging from 30° to 60°. The ability of the mica crystal to efficiently reflect radiation in multiple orders allowed us to cover the entire spectral range from 0.10 to 1.73 nm except for a gap from 0.86 to 1.00 nm. The experiment was carried out on Yang accelerator and aimed to investigate the characteristics of a high density plasma. Experimental results using cu
