| 摘 要： | 提出了一种单发实验测量软X射线波段多层膜反射镜反射特性的简易方法。实验采用激光等离子体软X射线源作为光源，用平焦场光栅谱仪分光，在光路中引入掠入射镜以消除高级次谱的影响，用软X光CCD记录，在一发激光打靶实验中，测量了设计中心波长为13.9 nm的Mo/Si多层膜反射镜的反射特性。

| Abstract: | A new method of single shot measurement of normal incidence soft X ray Mo/Si multilayer mirror's reflectance was proposed. Experiment were performed using laser produced plasma X ray source, flat field grating spectrometer and soft X ray CCD. Grazing incident mirror was employed to eliminate high order contribution. Wavelength was accurately determined by the 17.04nm L edge of Al filter. Measurements of Mo/Si multilayer mirror showed a peak reflectance of 35% at 14nm with a 0.5nm bandwidth. |

| Keywords: | Mo/Si multi layer mirror reflectance soft X ray laser produced plasma |
