Abstract

An X-ray high-precision slit device provided by the present invention includes a slit assembly, wherein the slit assembly includes a fixed cylindrical blade assembly and an adjustable cylindrical blade assembly, the adjustable cylindrical blade assembly and a flexible hinge Institutions are connected. The invention solves the technical difficulty of grinding the large-width knife edge and ensures its straightness. Further, the slit opening adjustment mechanism of the present invention has good operability, greatly improves the adjustment precision while ensuring parallelism, and can realize sub-micron adjustment.

Description

technical field [0001] The invention relates to the field of synchrotron radiation beamlines, and more particularly to an X-ray high-precision slit device. Background technique [0002] Synchrotron radiation has the characteristics of continuous spectrum, high brightness and good collimation, and the slit is an important part of the synchrotron radiation beamline, and its main function is to limit the size of the beam. In order to take full advantage of the advantages of synchrotron radiation, the slit, as the main beam limiting device, must have very high knife-edge straightness, knife-edge parallelism and motion accuracy. Generally speaking, according to the working energy area of ​​the slit, it can be divided into white light slit and monochromatic light slit. The performance of the monochromatic light slit is directly related to the pros and cons of the test data of the experimental station sample, so it has higher requirements for the knife edge parameters and the over...
