optical layout and structure of the variable included angle plane grating monochormator(VAPGM) at Shanghai Synchrotron Radiation Facility(SSRF) is introduced
and the factors that result in light spot transversal transfer are analyzed.Numerical simulation for the deformation under loads is done by using the Ansys code
and the dispensatory errors for relevant parts of the monochromator are decided based on the simulation results.The monochromator structure has been designed according to the dispensatory errors.After installation
the monochromator
was tested
and the transversal angle transfer repeatability was 0.7″.
