Cross sections with magnetic sublevels of He-like ions for polarized x-ray spectroscopy

In fast-ignition plasma, energy transport in dense plasma is one of the critical issues. The fast-ignition plasma emits polarized x-rays since the VDF of generated fast electron is anisotropic VDF. Spectroscopy of polarized x-ray is a useful diagnostics for studying the VDF of fast electrons. The time- dependent collisional-radiative atomic kinetics model was developed to analyze the experimental results of polarized Cl-He $\alpha$ line [1]. To examine the model calculation, the cross sections with magnetic sublevels of He-like Cl and Cu ions were calculated [2]. The calculated cross sections with magnetic sublevels for He-like ions will be discussed for polarized x- ray spectroscopy in the ultrahigh-intense laser (10$^{17}$~10$^ {20}$ W/cm$^{2}$). \newline [1] T.
