Abstract

Sagittal focusing double-crystal monochromator, which has the double functions that are dynamically monochromating synchrotron light and focusing the monochromatic light, is the kernel instrument of hard x-ray beam line in synchrotron radiation, and sagittal focusing crystal is the key part in the monochromator. The sagittal focusing monochromator, which is being manufactured, has energy range, 5 to approximately 20 KeV, focusing radius, 0.8 to approximately 5 m, focusing precision ΔR/R, better than 0.75%, and at 10 KeV, 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 focusing monochromator.
