激光等离子体X光辐射非平衡特性实验研究

EXPERIMENTAL INVESTIGATIONS OF NONEQUILIBRIUM CHARACTER OF X-RAY RADIATION FROM LASER PLASMA

摘要: 在LF-11和LF-12高功率激光装置上进行的实验中,设计了一些特定的激光束-金腔靶-探测器条件,创造了激光直接加热、准辐射加热和激光、X光混合加热三种物理条件,采用软X光透射光栅能谱时空分辨技术,测量了腔靶、缝靶和双孔靶等高分辨X光能谱,研究了激光等离子体X光辐射非平衡特性。

Abstract: Diagnoses of space-and time-resolved spectra of X-rays emitted from laserplasmas were performed by means of a soft X- ray grating combined with a pinhole or a slitand a soft X- ray streak camera,respectively.The nonequilibrium characteristic band spectra oflaser plasmas were observed and studied.
