Combined X-ray monochromatic convergence system

Abstract

The invention discloses a combined X-ray monochromatic convergence system, which comprises an X-ray generator and a plurality of focusing units, and is characterized in that each focusing unit comprises a multi-capillary X-ray parallel beam lens, a monochromator and a multi-capillary X-ray focalizer which are connected in sequence; the X-ray generator is a point light source and radiates and emitsX-rays to the periphery by taking a point as a source; the multi-capillary X-ray parallel beam lenses of the plurality of focusing units are arranged on an outward radiation light path of the X-ray generator; and the multi-capillary X-ray focalizers of the plurality of focusing units have a converged final focus. According to the combined X-ray monochromatic convergence system, a plurality of focusing units can be arranged through the X-ray light source with the large emergence angle. The multiple focusing units finally have a converging micro-focus. Compared with other X-ray monochromatic focusing devices, the X-ray monochromatic focusing device has the advantages that the X-ray utilization rate is high, and the brightness of a focusing focal spot is higher.

Description

technical field [0001] The invention relates to the technical field of optical control, in particular to a combined X-ray monochromatic focusing optical system. Background technique [0002] Since X-ray was discovered by German physicist W.K. Roentgen in 1895, it has been a powerful tool for people to explore the microscopic world, and has a wide range of applications in medical imaging, industrial inspection, physics, chemistry and biological analysis. In practical applications, the most commonly used X-rays are produced by X-ray tubes. The X-rays produced by the X-ray tube are polychromatic and divergent X-rays. However, in the field of X-ray spectroscopic analysis, especially in the field of micro-area X-ray analysis, a monochromatic focused X-ray beam is often required. At present, the most commonly used X-ray focusing monochromator is X-ray multilayer film or curved crystal monochromator. Both X-ray multilayer film and curved crystal monochromator require precise man...

AI Technical Summary

Problems solved by technology

Both X-ray multilayer film and curved crystal monochromator require sophisticated manufacturing technology, so the cost is relatively expensive, and it is difficult to widely promote

The polycapillary X-ray lens is also a commonly used X-ray converging device, and its cost is low, which is conducive to widespread promotion, but the polycapillary X-ray converging lens does not have a monochromatic effect.
