杰斐逊实验室建造了一台同步加速器光干涉仪，用于测量小于衍射极限的小光束尺寸。该装置是非侵入性的，可以监测几微安电子束的轮廓。它遵循T.Mitsuhashi首创的设计，是CEBAF加速器的宝贵仪器。文中介绍了干涉仪的结构、安装过程中的经验和一次光束的测量结果。该装置的未来应用包括精确的能量扩散监测(/SPL sim/10/sup-5/)，这是一些霍尔A核物理实验所需要的。
A synchrotron light interferometer has been built at Jefferson Lab in order to measure small beam sizes below the diffraction limit. The device is noninvasive and can monitor the profile of a few microampere electron beam. It follows the design pioneered by T. Mitsuhashi and is a valuable instrument for the CEBAF accelerator. The structure of the interferometer, the experience gained during its installation, and first beam measurement results are presented. Future applications of this device include precise energy spread monitoring (/spl sim/10/sup -5/) which is required by some Hall A nuclear physics experiments.
