Monochromator crystal orientation method

Abstract

The invention relates to a color device crystal orientation method which comprises the following steps: S1, mounting a to-be-cut crystal on a manual adjustment arc swing table, and fixing the to-be-cut crystal; s2, the to-be-cut crystal is cut, the cut to-be-cut crystal is subjected to primary orientation, and the angular deviation of the cut to-be-cut crystal in the x direction and the y direction is obtained; s3, adjusting the angle of the to-be-cut crystal by utilizing a manual adjusting arc swinging table and an autocollimator; s4, after the angle of the to-be-cut crystal is adjusted, the to-be-cut crystal is cut again, the to-be-cut crystal cut again is oriented again, and the angle deviation of the to-be-cut crystal cut again in the x direction and the y direction is obtained; s5, judging whether the angular deviation of the to-be-cut crystal cut again in the x direction and the y direction is smaller than 1 'or not, and if yes, ending the step; and if not, repeating the steps S3 to S4.

Description

technical field [0001] The present invention relates to the field of synchrotron radiation beamlines, and more particularly to a monochromator crystal orientation method for synchrotron radiation beamlines. Background technique [0002] Synchrotron radiation is an excellent X-ray light source. It has the advantages of high collimation, high brightness, low divergence, and continuously adjustable wavelength. It has injected new life into X-ray spectroscopy, topography, structural analysis, crystal diffraction and other application fields. machine. Because the atomic layer spacing of a perfect crystal is of the same order of magnitude as the X-ray wavelength scale, X-ray monochromaticity can be achieved by separating the desired single-wavelength spectral line from the incident X-ray by using the crystal. A crystal that achieves a monochromatic function is commonly referred to as a monochromator crystal in synchrotron radiation. [0003] The monochromator crystal is the core...

Problems solved by technology

[0008] In the actual processing of the above steps, the corresponding rotating platform needs to work in the cutting fluid environment, the working environment is harsh, and the high-precision electric arc swing table is easily damaged and cannot be used.

However, the manual rotating platform usually only achieves a rotation accuracy of 12', which is unable to meet the high-precision orientation requirements of the monochromator crystal 1'.
