Study on Checking and Measuring for Sagittal Double Crystal Monochromator
弧矢聚焦双晶单色器性能测试研究

The check and measure methods of Bragg angle step and precision etc. parameters with high precision autocollimation are investigated.Adjustment angles of crystal have been magnified using parallel ray of monochromator,to checking and measuring performance of adjustment mechanism.Simulated ray of the beamline has been built to check and measure sagittal focusing facula.Performance checking and measuring of the first sagittal focusing monochromator in internal had been successfully achieved out of beamline,checking and measuring results in according with theory design index,indicating validity of those methods.
