x射线谱仪

In the region of shorter wavelength ( r < 10nm ) , measurement reflectivity is much lower than design reflectivity , so the making of high reflectivity multilayer mirrors is at the phase of exploring . the aim of the paper is to design and fabricate five mulitilayer mirrors in shorter wavelength of soft x ray region and makes up of soft x ray spectrometer which is applied to icf experiment
本论文所完成的是在软x射线短波段的五个波长处(最短波长为1 . 03nm ) ，研制具有实用反射率的软x射线多层膜反射镜，并应用于惯性约束核聚变( icf )实验中的软x光能谱测量。
