摘要

A combined system of a polycapillary focusing X-ray lens (PFXRL) and a cylindrical polycapillary collimator (CCC) is proposed to obtain a quasi-parallel X-ray microbeam from an ordinary X-ray source. The orders of magnitude of the beam size, gain of power flux density, and divergence of the quasi-parallel X-ray microbeam are 10 μm, 10², and milliradian, respectively.
