Development of Scanning Reflection Electron Holography Microscopy (SREHM)

研制了扫描型反射式电子束全息显微镜。通过本课题的研究，取得了如下成果。(1)首次研制了超高真空反射式电子显微镜，并在此显微镜下成功地观察到Pt（100）表面的重构畴（论文#1）。（2）设计了一种新型的SREHM样品保持器。该保持器使得能够以高精度控制入射角和方位角的沿沿着X和Y方向的移位和旋转。（3）成功地获得了沿着超导导线电场的显微图及其全息图。（4）建立了一套具有红外辐射加热系统和Zr-O/W（100）TF发射体的SREHM系统，并取得了初步的实验结果，证实了SREHM的巨大潜力（5）

Scanning type reflection electron beam holography microscopy (SREHM) has been developed. The resualts obtained though the present research project are as follows.(1) UHV Reflection electron microscope was, first, developed and we succeeded to observe the reconstructed domains on Pt(100) under this microscope (paper #1)(2) A new type sample holder for the SREHM ws also designed. This holder enables shifts along X and Y directions and rotation for incident and azimuthal angles to be controlled with high precision. (paper #2)(3) Micro mapping of electric field along superconducting wire and its hologram have been successfully obtained. (paper #4)(4) The SREHM system with infrared-radiation heating system and Zr-O/W(100) TF emitter has been contructed, and a prelimary result was enconrageous enough to confirm very high potentiality of the SREHM (paper #5)
