A synchrotron light interferometer has been built at Jefferson Lab in order to measure small beam sizes below the diffraction limit. The device is non-invasive 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 with its use are presented.
