Abstract

Since the recent invention by Kumakhov of polycapillary optics for the control of x-ray beams, a large number of potential applications have been identified. These include materials analysis techniques such as diffraction and microfluorescence, lithography, medical imaging applications such as angiography and mammography, and medical therapy. To develop and further identify these applications, precise knowledge is needed of the performance of a variety of capillary types for different source energies and geometries. Extensive measurements have been performed of transmission and exit divergence as a function of length, bend radius, x-ray source position, and x-ray energy (from 1 to 44 keV). X-ray source divergence was also varied; measurements were performed with point sources and synchrotron beams. The measurements were performed for a variety of polycapillary compositions, diameters, and geometries. In general, data agrees fairly well with Monte Carlo geometrical simulations.
