Study of Ar K-shell spectra from Z-pinch experiments on Yang Accelerator

Ar K-shell Spectra were measured using an elliptical crystal spectrometer in gas-puff Z-pinch experiments performed on Yang Accelerator (peak current 800 kA, rise time 90 ns). To estimate from the spectra the electron temperature of the plasma, a collisional-radiative (CR) model was developed. By comparing the line ratio of Lyα and Hea derived from the experimental results with those predicted by the model, time and space averaged electron temperature value was obtained.
