摘要：

We describe and characterize a new x-ray optical system in which x rays are steered using multiple reflections within hollow glass capillary tubes. The prototype beam-shaping collector/collimator evaluated for diffraction with CuK(alpha) x rays in this letter has throughput of 6% and increases the useful x-ray flux by more than a factor of 4 above that of slit collimation with comparable divergence.
