Technology of the sagittal focusing crystal manufacturing and testing for monochromator in Synchrotron Radiation

摘要

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 they key part in the monochromator. The sagittal focussing monochromator, which is being manufactured, has energy range, 5 approx 20KeV, focusing radius, 0.8 approx 5m, focusing prcision DELTA R/R, better than 0.75
