摘要：

We are constructing an X-ray intensity interferometer and an undulator beamline to demonstrate intensity interferometry in the soft X-ray region. The 10-period X13 soft X-ray undulator at the National Synchrotron Light Source will provide the coherent flux; the X13A beamline will preserve the brightness of the X-ray beam and provide sufficient temporal coherence with a horizontally deflecting spherical grating monochromator. Using the interferometer, which consists of an array of small slits, a wedge-shaped beamsplitter and two fast microchannel plate detectors, we expect to measure the spatial coherence of the undulator beam and therefore the size of the source. The beamline design and the interferometry experiment are discussed.
