[Abstract]:Spatial resolution and focusing efficiency are the key technical parameters of X-ray microprobe. Bending non-spherical mirror has the advantages of high focusing efficiency, good spatial resolution, low processing difficulty and dispersion elimination. Based on the existing conditions of hard X-ray microfocus of Shanghai light source and the application of line station, a high-precision flexure hinge bending mechanism is designed based on the accurate bending theory, and the finite element analysis is carried out, and the body width of the bending mirror is further optimized. By measuring the bending mechanism with (Long Trace Profiler,LTP), it is found that the slope error of the bending non-spherical mirror is 430 nrad,. In theory, the hard X-ray focusing spot of 230 nm can be realized.
