摘要
本文提出了软X射线条纹相机与吸收膜相耦合测量等离子体温度的实验原理与方法,编制了数值计算程序SCC,给出了平面金靶在1.06μm激光(LF—II~=激光装置)作用下,靶面功率密度约10^(14)W/cm^2的辐射温度。并对温度处理中存在的误差,以及把此方法推广到能谱的时间分辨和温度的空间分辨测量中的可能性进行了讨论。
A method has been devloped for measuring radiation temperatures using a set of absorption-foils coupled to a soft X-ray streak camera in bser plasma experiments. A numerical code for deriving the streak camera measured temperature computation, SCC, has been developed and the result has been given for a planar gold target irrdiated by laser(λ=1.06μm )pulses of about 360ps in duration with average intensities of about 1014w/cm2 from the LF-ll# Nd-glass laser facility. In addition, applications to measuring time-resolved spectra and space-resolved temperature are discussed.
