Abstract
We measure the spatial coherence function of a quasi-monochromatic 1.1 keV X-ray beam from an undulator at a third-generation synchrotron. We use a Yo ung's slit apparatus to measure the coherence function and find that the co herence measured is poorer than expected. We show that this difference may be attributed to the effects of speckle due to the beamline optics. The con ditions for successful coherence transport are considered. (C) 2001 Elsevie r Science B.V.
