Recent Progress of X-Ray Laser at Shenguang II: Diagnosing ICF Plasma by Ni-Like Ag 13.9nm X-Ray Laser

Abstract

Plasma produced by laser irradiation of CH slab target was diagnosed by Mach-Zehnder (M-Z) interferometer, and the plasma produced by laser irradiation of plane CH modulation target which was used to study nonlinear development of ablation Rayleigh-Taylor (RT) instability, were also diagnosed by M-Z interferometer and by side-on radiography using an Ni-like Ag soft X-ray laser (XRL) at 13.9nm as probe light. Two-dimensional electronic density profile of CH slab target up to a density of 3.2x10(21) cm(-3) had been obtained. Furthermore, the nonlinear development of ablation RT instability also had been observed by M-Z interferometer and side-on radiography using a soft XRL as probing light. In this paper, the experiment arrangement and the experiment results were reported, and the primary analysis on it also was represented.
