“…The second order R(h x ) was derived from the first order data 22 based on the formulas described in Ref. 23. The sharp edge in the curve around 2.4 keV corresponded to the L-shell absorption edge of thallium (Tl) in the TlAP crystal.…”

Plasma parameters of molybdenum (Mo) X-pinches on the 1-MA QiangGuang-1 facility were estimated by L-shell spectral analysis. X-ray radiation from X-pinches had a pulsed width of 1 ns, and its spectra in 2-3 keV were measured with a time-integrated X-ray spectrometer. Relative intensities of spectral features were derived by correcting for the spectral sensitivity of the spectrometer. With an open source, atomic code FAC (flexible atomic code), ion structures, and various atomic radiativecollisional rates for O-, F-, Ne-, Na-, Mg-, and Al-like ionization stages were calculated, and synthetic spectra were constructed at given plasma parameters. By fitting the measured spectra with the modeled, Mo X-pinch plasmas on the QiangGuang-1 facility had an electron density of about 10 21 cm À3 and the electron temperature of about 1.2 keV.

“…4and θ = 30 • −60 • , the X-ray wavelength analyzed by the mica crystal is in the range of 0.992 − 1.718 nm. We may relate the Bragg angle θ to the spectral detection angle β for the given elliptical geometry by [11,12] β = θ + cos −1 cos θ e . The bent crystal spectrometer system is mainly composed of the dispersive element, the vacuum configuration, and the spectral detector.…”

A wide variety of X-ray and extreme ultraviolet diagnostics are being developed to study on Yang accelerator. An elliptically bent crystal spectrometer is designed with a focal length of 1350 mm. A mica crystal with an interplanar spacing of 1.984 nm bent onto an elliptical substrate with eccentricity of 0.9485 is used. The crystal analyzer covers the Bragg angle range from 30 • to 60 •. The mica crystal can efficiently reflect radiation in multiple orders, covering the entire spectral range from 0.1 to 1.73 nm except for a gap from 0.86 to 1.0 nm. The application experiment is performed on Yang accelerator using the bent mica crystal analyzer. Spectra of neon-puff Z-pinch plasmas are recorded with a X-ray film, showing the H-like and the He-like lines of neon. Each spectrum has been identified and used for the wavelength calibration, and most of the line radiation is contained in the He-α and the L-α lines. The experimental results have demonstrated that the spectral resolution approximates 379.
