在高真空环境下使用McPHERSON 2 4 7型掠入射单色仪测量了纳秒激光激发的Fe等离子体 5～ 2 7nm波段的软X射线光谱 ,单色仪光谱分辨率Δλ≤ 0 .0 75nm ,波长扫描间隔 0 .1nm ,认证出了若干电离Fe的强谱线。
The soft X-ray spectrum of 5 ~ 27nm band of Fe plasma excited by nanosecond laser was measured by McPHERSON 2 4 7 grazing-incidence monochromator under high vacuum environment. The spectral resolution of monochromator Δλ≤0. 0 75nm, Wavelength scan interval 0 .1nm, certified a number of strong ionization Fe line.
