2-BEAM DYNAMICAL-APPROACH TO MULTIPLE SUCCESSIVE DIFFRACTORS IN X-RAYCRYSTAL 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 an d 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 be am conditioners have been devised, constructed, and tested. High spati al resolution of the X-ray magnifier when applied to synchrotron radia tion and relatively low intensity of the X-rays passed from sealed off X-ray tube through the monolithic X-ray magnifier and through the nea r-coplanar beam conditioner are discussed.
