Two-beam dynamical approach to multiple successive diffractors in X-ray crystal optics

To devise and optimise new monolithic components for X-ray diffraction optics more and more refined theoretical procedures are required. In addition to the simple geometrical approach utilising the vector Bragg equation, the two-beam dynamical approach including the asymmetric and tilted cases has been worked out for multiple successive diffractors. Based on the conditions derived and on the refined imaging equations for beam tracing, several types of monolithic X-ray magnifiers and beam conditioners have been devised, constructed, and tested. High spatial resolution of the X-ray magnifier when applied to synchrotron radiation and relatively low intensity of the X-rays passed from sealed off X-ray tube through the monolithic X-ray magnifier and through the near-coplanar beam conditioner are discussed.We would like to thank Prof. B.K.
