摘要：

By a simple implementation of the bent-perfect-crystal (BPC) elements on conventional scattering devices one can considerably benefit from real and/or momentum space focusing, especially for small slit-like samples or when a high angular and wavelength resolution is required. Working with open beams without Soller collimators the diffraction devices equipped with the BPC-elements in combination with position-sensitive detectors can be dramatically superior to the conventional devices with flat mosaic crystals. In this paper we review the basis of the Bragg diffraction optics and its practical applications as they were proposed and tested in the last decade within the collaboration between NPI, PTB, ILL and KURRI.
