LaB_6电子枪发射的电子束经过静电聚焦系统，被会聚为微米级的电子束斑，该微束斑电子束与固体金属靶相互作用，产生出微束斑的X射线，从而形成微束斑X射线源。

Microscopic characteristics of cladded crystal fiber are analyzed by X-ray diffraction, Laue X-ray diffraction and scanning electron microscopy, it is found that magnesium-ion indiffusion does not affect the single crystal structure and the domain structure of the magnesium diffused crystal fiber. It is found for the first time that MgO-rich layer in the magnesium diffused LiNbO〓 surface layer exhibits the crystal structure of an unknown compound from the Li-Mg-Nb-O ternary system and MgNb〓O〓. It is proposed for the first time that this unknown compound and MgNb〓O〓 in MgO-rich layer are the real sources of magnesium-ion indiffusion LiNbO〓. Their appearance indicate that MgNb〓O〓 is in the surface layer of MgO-rich layer, the unknown compound is in the subsurface layer and beneath where the MgNb〓O〓 is located, and these compounds have obviously preferred orientation.

通过镁离子内扩散法，首次在国内实现了具有阶跃和抛物折射率分布的c轴LiNbO〓单晶光纤和a轴Nd：MgO：LiNbO〓单晶光纤的芯—包层波导结构，为我国在该项目的研究填补了空白；建立了晶纤损耗的测量系统，提出了利用单模石英光纤作为晶纤入射光耦合器的思想；通过对晶纤损耗的测量，得到了包层晶纤比未包层晶纤损耗降低约14倍的好结果，并实现了低次模传输：对经镁离子内扩散实现包层后的晶纤的微观特性，利用X射线衍射，劳厄照相和扫描电镜表征发现，晶纤并不因镁离子的内扩散而影响其单晶结构和镁的扩散层畴的变化。
