摘要：
Polycapillary optics are arrays of thousands of hollow capillary tubes. Focal spots are produced from the overlap of outputs from multiple channels at distances of 10-100 mm from the output of the optic. Synchrotron focusing was performed with two polycapillary X-ray optics. The spot size for the monolithic optic was 80 mu m, which yielded a measured gain in photon flux through a 350 mu m pinhole of nearly 100. Gains up to an order of magnitude larger are expected for smaller pinholes. White beam focusing was also demonstrated. (C) 1997 Published by Elsevier Science B.V.
