Abstract

The author discusses an undulator at the Advanced Photon Source (APS) as a source for intensity interferometry. An approach is presented for the measurement of the particle beam size based on X-ray intensity interferometry. Two technically feasible schemes are proposed and analyzed. This type of interferometer will provide a resolution of a few tenths of a micron for a positron beam that emits undulator radiation. The minimum required time for the measurement is about 30 s. The feasibility of intensity interferometry for the APS undulator is demonstrated. In addition, it is shown that both an acceptable time scale for measurements and the spatial resolution are readily available.<>
