A split aperture device

Abstract

The present invention relates to a spectroscopic diaphragm device, which comprises: a spectroscopic main body, two openings forming an included angle between each other are opened in the spectroscopic diaphragm, and are used for respectively passing two light beams in a composite beam line entering the spectroscopic main body. A light hole with a grazing incidence structure, the light hole extends from the left end to the right end of the light splitting body, and the angle between the two light holes is the same as the angle between the two light beams in the composite beamline The included angles are the same, so that the central axis of each of the light holes coincides with the central ray of the light beam passing therethrough; a water cooling circulation system; a plurality of collimating elements; and at least one temperature detector. In the present invention, two light-through holes are arranged in the beam splitting main body to respectively allow two light beams in the compound beam line to pass through, so as to realize the light splitting of the compound beam line. The invention has a compact structure, takes up little space, and is equipped with a special collimation element, which facilitates the installation and collimation of the device.

Description

technical field [0001] The invention relates to the field of synchrotron radiation light sources, in particular to a spectroscopic aperture device. Background technique [0002] Synchrotron radiation is an electromagnetic wave emitted along the tangential direction of the electron trajectory due to the change of state (speed and direction) when free electrons move in a magnetic field. Due to the characteristics of continuous spectrum, high brightness, and good collimation, it is widely used in physics, chemistry , life science, information science, energy and environmental science and many other scientific research and high-tech fields have a wide range of applications. The front-end area is an important part of the synchrotron radiation device. It is self-contained and associated with multiple systems. Its main functions are to limit the size of the synchrotron radiation light, detect the beam position, absorb heat load, and realize the safety protection of downstream equip...

Problems solved by technology

[0007] If the equipment is not used to split the Canted beam, but the two synchrotron radiation beams are naturally separated according to their angles, and then the beam is limited, detected, and absorbed heat load, etc., it will require a lot of space, and because the beam itself The diffusibility of equipment components used in the future will inevitably increase, which will increase the cost of equipment and the difficulty of installation. At the same time, it will also increase the work of process facilities, installation and maintenance of safety chains, and maintenance of ultra-high vacuum. This not only increases the overall construction and maintenance costs, but also increases the construction, installation space and labor workload of workers
