Sagittal focusing double-crystal monochromator, which has the double functions that are dynamically monochromatingsynchrotron light and focusing the monochromatic light, is the kernel instrument of hard x-ray beam line in synchrotronradiation, and sagittal focusing crystal is the key part in the monochromator. The sagittal focusing monochromator, which isbeing manufactured, has energy range, 5-2OKeV, focusing radius, O.85m, focusing precision AR/R, better than 0.75%, and at 1OKeV, meridional anticlastic deformation, less than 1.8 arcsec, sagittal focusing slope error, less than or equal to 2 arcsec.This paper discusses the design, manufacturing and testing about the sagittal focusing crystal in the sagittal focusingmonochromator.Key words: crystal, manufacture, test, synchrotron radiation 1. INTRODUCTION Synchrotron radiation light source, which follows after the source of electric lighting, X-radiation and laser, is a novel onewho bring revolutionary force for human civilization, forcing development of science and technology by highly luminance,intensity, collimation and continuous spectrum. Monochromator is the "heart" of the beam line, who makes the synchrotronradiation light become the right energy, wave length, resolution that lab needs, sagittal focusing crystal is an importantdevice in sagittal focusing double-crystal monochromator, which makes monochromic x-ray change direction and focus inright position. As a consequence of Hooke ' |
