Description

Technical Field

[0001] This utility model belongs to the field of synchrotron radiation technology and relates to a liftable photon shutter absorber that can be used with dual inserts in synchrotron radiation beamlines and is applied in a high vacuum environment. Background Technology

[0002] The High Energy Synchrotron Radiation Facility (HERF) currently under construction in Huairou, Beijing, is the world's brightest fourth-generation synchrotron radiation facility to date. With the continuous development of synchrotron radiation technology, more and more beamlines on high-energy synchrotron radiation facilities are adopting a dual-insertion configuration. This dual-insertion configuration allows for different experimental conditions and spectral characteristics to be obtained within the same beamline, thereby maximizing the utilization efficiency of the light source. Typically, the dual-insertion configuration includes both a undulator and a gyroscope. The synchrotron radiation emitted by the undulator source has a higher thermal power density, while the synchrotron radiation emitted by the gyroscope source has higher thermal power and a larger beam size. Therefore, the dual-insertion configuration presents significant challenges to the thermal load-bearing capacity and heat dissipation of the main light-blocking components on the synchrotron radiation beamline.

[0003] The photonic shutter is a switch for synchrotron radiation beamline light, a crucial light-blocking component. The absorber is a key part of the photonic shutter; its specially structured structure controls the switching on or off of synchrotron radiation by entering or exiting the optical path. When the absorber enters the optical path, the synchrotron radiation is absorbed or blocked, thus turning off the light. When the absorber exits the optical path, the synchrotron radiation can pass through smoothly, achieving the switching on operation. Through this precise control of the absorber's position in the optical path, the photonic shutter can stably and efficiently switch synchrotron radiation, meeting the stringent beam control requirements of synchrotron radiation beamline experiments.

[0004] Traditional lift-type photonic shutter absorbers mostly employ a grazing incidence method when receiving synchrotron radiation. Specifically, the surface receiving the synchrotron radiation is typically an inclined plane forming a certain angle with the synchrotron radiation along the optical axis. These traditional lift-type photonic shutter absorbers are characterized by a short axial length, a small radial width, and a single, relatively large inclined plane. Due to these structural limitations, they can only effectively receive small light spots and low-power heat loads, making them unsuitable for handling complex conditions with large light spots and high power. Regarding cooling solutions, traditional lift-type photonic shutter absorbers often use a method of bending one or two water pipes and welding them to the inner wall of the absorber's groove to remove heat. This cooling method has limitations in heat dissipation efficiency and uniformity, failing to fully meet the heat dissipation requirements of the absorber under high-load operation, thus restricting the performance of photonic shutters in high-performance applications. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a liftable photonic shutter absorber that can be used with two inserts. This absorber can simultaneously receive high-power-density synchrotron white light emitted by the undulator insert, high-total-power but low-power-density synchrotron white light emitted by the oscillator insert, and low-power synchrotron monochromatic light with a certain positional offset. The two inserts have different spot sizes; one insert emits light with a small spot and high heat density, while the other insert emits light with a large spot and high total heat. The light emitted by the inserts is collectively referred to as white light, and monochromatic light refers to white light processed by a certain optical element. It is generally offset from the center of the optical path by a certain distance, thus determining the vertical height of the absorber. This absorber moves vertically up and down to switch synchrotron radiation on and off. The light-receiving surface of the absorber is composed of multiple inclined planes at different angles, which are connected in sequence to form a segmented design that effectively shortens the length of the absorber and saves space on the beamline. The absorber has two independent cooling water channels inside, with water outlet pipes welded to the inlet and outlet of the cooling water channels to lead out the cooling water. This cooling solution has a large cooling area, which can greatly improve the cooling efficiency, reduce the impact of the high heat load of synchrotron radiation on the absorber, and also significantly reduce the welding area between the absorber and the water outlet pipes, thus reducing the risk of vacuum leakage.

[0006] The technical solution of this utility model is as follows:

[0007] A liftable photonic shutter absorber that can be used with two inserts is characterized in that it includes an absorber body 1, a water outlet pipe 2, a transition pipe 3, and a sealing flange 4.

[0008] One end of the transition tube 3 is fixedly connected to the upper end of the absorber body 1, and the other end is connected to the sealing flange 4;

[0009] The water outlet pipe 2 includes an inlet pipe and an outlet pipe. One end of the outlet pipe is connected to the cooling water inlet and outlet of the absorber body 1, respectively, and the other end passes through the holes on the transition pipe 3 and the sealing flange 4 in sequence. The water outlet pipe 2 is connected and fixed to the sealing flange 4.

[0010] The absorber body 1 is used to receive synchrotron white light emitted by the undulator insert, synchrotron white light emitted by the oscillator insert, and synchrotron monochromatic light; the synchrotron white light and the synchrotron monochromatic light are parallel to each other along the optical axis in the same vertical plane, and the synchrotron monochromatic light is located above the synchrotron white light.

[0011] The lower end and front end surfaces of the absorber body 1 are light-receiving surfaces; the light-receiving surfaces are inclined planes with multiple different angles to synchrotron radiation along the optical axis, and the multiple inclined planes are connected in sequence to form a segmented design of the light-receiving surface.

[0012] Furthermore, the length of the absorber body 1 along the optical axis is determined by the sum of the lengths of each light-receiving surface multiplied by the cosines of the corresponding tilt angles; the width of the absorber body 1 is determined by the spot size of the synchrotron radiation light output by the insert light source on the light-receiving surface; the height of the absorber body 1 is determined by the sum of the lengths of each light-receiving surface multiplied by the sines of the corresponding tilt angles and the distance between the beam center of the synchrotron radiation monochromatic light and the beam center of the synchrotron radiation light.

[0013] Furthermore, the tilt angle of each light-receiving surface of the absorber body 1 relative to the synchrotron radiation along the optical axis is determined by the surface power density distribution of the insert light source at the corresponding inclined surface position; the length and width of each light-receiving surface are determined by the spot size of the insert light source at the corresponding light-receiving surface position.

[0014] Furthermore, each of the aforementioned light-receiving surfaces cuts into the optical path vertically downwards, and is sequentially defined as the first light-receiving surface 11, the second light-receiving surface 12, and the third light-receiving surface 13 according to the order in which they cut into the optical path and receive synchrotron radiation. The first light-receiving surface 11 is used to receive the entire area of ​​the high-power-density, small-spot synchrotron white light emitted by the undulator insert or the central area of ​​the high-total-power, large-spot synchrotron white light emitted by the oscillator insert. The second light-receiving surface 12 is used to receive the area other than the central area of ​​the high-total-power, large-spot synchrotron white light. The third light-receiving surface 13 is used to receive the synchrotron monochromatic light.

[0015] Furthermore, the first light-receiving surface 11 forms an angle α11 with the synchrotron radiation along the optical axis, the second light-receiving surface 12 forms an angle α12 with the synchrotron radiation along the optical axis, and the third light-receiving surface 13 forms an angle α13 with the synchrotron radiation along the optical axis; wherein, α13>α12>α11.

[0016] Furthermore, α3 is 90°.

[0017] Furthermore, the water outlet pipe 2 includes two inlet pipes and two outlet pipes; the absorber body 1 is provided with two independent cooling water channels, namely the first cooling water channel 14 and the second cooling water channel 15; the first inlet pipe and the first outlet pipe are respectively connected to the cooling water inlet and outlet of the first cooling water channel 14; the second inlet pipe and the second outlet pipe are respectively connected to the cooling water inlet and outlet of the second cooling water channel 15; the first cooling water channel 14 and the second cooling water channel 15 are both parallel to the first light-receiving surface 11 and are a certain distance away from the first light-receiving surface 11.

[0018] Furthermore, the first cooling water channel 14 and the second cooling water channel 15 have the same structure and are symmetrically distributed along the optical axis; the first cooling water channel 14 is formed by two transverse cooling water channels, three longitudinal water channels, and two vertical water channels intersecting and connected in pairs perpendicularly; wherein, the first longitudinal cooling water channel 143, the second longitudinal cooling water channel 144, and the third longitudinal cooling water channel 145 are equally spaced from the rear end of the absorber body 1 to the opposite side; the first transverse cooling water channel 141 is arranged from the outer side of the absorber body 1 near the front and rear ends and runs through the second longitudinal cooling water channel 144 to the opposite side. The first longitudinal cooling water channel 143 and the second longitudinal cooling water channel 144 are connected by a third longitudinal cooling water channel 145 and a second transverse water channel 142; a first vertical cooling water channel 146 is opened downward from the upper end face of the absorber body 1 near the rear end position and is connected to the first longitudinal cooling water channel 143 to form the inlet 16 of the first cooling water channel 14; a second vertical cooling water channel 147 is opened downward from the upper end face of the absorber body 1 near the front end position and is connected to the third longitudinal cooling water channel 145 to form the outlet 17 of the first cooling water channel 14.

[0019] Furthermore, the first light-receiving surface 11, the second light-receiving surface 12, and the third light-receiving surface 13 are all symmetrical about the center of the optical axis.

[0020] This application mainly consists of an absorber body, a water outlet pipe, a transition pipe, a sealing flange, and a sealing plug. The absorber body receives high-power-density synchrotron white light emitted by the undulator insert, high-total-power, low-power-density synchrotron white light emitted by the oscillator insert, and synchrotron monochromatic light. The synchrotron monochromatic light is formed by modulating the synchrotron white light using optical elements. The synchrotron white light and the synchrotron monochromatic light are parallel along the optical axis in the same vertical plane, with the synchrotron monochromatic light positioned slightly above the synchrotron white light by a certain distance.

[0021] The lower and front surfaces of the absorber body are the light-receiving surfaces for receiving synchrotron radiation. The light-receiving surfaces are inclined planes with multiple different angles to the synchrotron radiation along the optical axis. The multiple inclined planes are connected in sequence to form a segmented design of the light-receiving surface, which can effectively shorten the length of the absorber body and save space occupied by the beamline.

[0022] The tilt angle between the light-receiving surface of the absorber body and the synchrotron radiation along the optical axis is determined by the surface power density distribution of the insert light source at the corresponding inclined surface position. The length and width of each light-receiving surface are determined by the spot size of the insert light source at the light-receiving position on the light-receiving surface.

[0023] The length of the absorber body along the optical axis is determined by the sum of the lengths of each of the light-receiving surfaces multiplied by the cosines of their corresponding tilt angles; the width of the absorber body is the dimension of the absorber in the horizontal plane perpendicular to the optical axis, determined by the spot size of the synchrotron radiation emitted by the insert light source on the light-receiving surface; the height of the absorber body is the dimension of the absorber in the vertical plane perpendicular to the optical axis, calculated by the sum of the lengths of each of the light-receiving surfaces multiplied by the sines of their corresponding tilt angles, plus the offset distance between the center of the synchrotron monochromatic light beam and the center of the synchrotron radiation light beam.

[0024] The light-receiving surfaces cut into the optical path vertically downwards, and are defined as the first light-receiving surface, the second light-receiving surface, and the third light-receiving surface in the order of cutting into the optical path and receiving synchrotron radiation.

[0025] The first, second, and third light-receiving surfaces are all symmetrical about the center of the optical axis. The first light-receiving surface has a small angle with the synchrotron radiation along the optical axis and is used to receive the entire area of ​​the synchrotron white light emitted by the undulator insert or the central area of ​​the synchrotron white light emitted by the oscillator insert; the second light-receiving surface has the second smallest angle with the synchrotron radiation along the optical axis and is used to receive the area other than the central area of ​​the synchrotron white light emitted by the oscillator insert; the third light-receiving surface has a large angle with the synchrotron radiation along the optical axis and is used to receive synchrotron monochromatic light.

[0026] This segmented design of the light-receiving surface enables the absorber to simultaneously receive high-power-density synchrotron white light emitted by the undulator insert, high-total-power, low-power-density synchrotron white light emitted by the oscillator insert, and synchrotron monochromatic light with a certain positional offset. It also effectively shortens the length of the absorber and saves space on the beamline.

[0027] Inside the absorber body, two independent cooling water channels are arranged parallel to the first light-receiving surface that bears the most heat load and at a certain distance from the first light-receiving surface. The distance between the cooling water channels and the first light-receiving surface can be 10 mm to 20 mm, which is specifically calculated by finite element thermal analysis.

[0028] The cooling water channels are circular channels, with two channels having the same structure, independent of each other, and symmetrically distributed along the optical axis. Each channel is formed by two transverse cooling water channels, three longitudinal water channels, and two vertical water channels that intersect and connect in pairs perpendicularly. Three longitudinal water channels are drilled from the rear end surface of the absorber to a certain depth, and the three water channels are arranged at equal intervals. Two transverse cooling water channels are drilled from the inner or outer side of the absorber body near both ends to a certain depth, with the transverse water channel near the rear end connecting to the two longitudinal water channels, and the transverse water channel near the front end connecting to the two longitudinal water channels. From the upper surface of the absorber body, at the position of the innermost longitudinal water channel near the rear end, a vertical cooling water channel is drilled downwards, connecting to this longitudinal cooling water channel to form a water inlet. From the upper surface of the absorber body, at the position of the outermost longitudinal water channel near the front end, a vertical cooling water channel is drilled downwards, connecting to this longitudinal cooling water channel to form a water outlet. The water outlet pipes are welded to the water inlet and outlet of the absorber body. Sealing plugs are welded to the ends of the remaining circular channels on the surface of the absorber body, thus forming a series of cooling water channels. The other cooling water channel is treated similarly.

[0029] The design of two independent cooling water channels inside the absorber body ensures that the longitudinal cooling water channels are evenly distributed above the first light-receiving surface, which can effectively remove the heat of synchrotron radiation of various sizes, greatly improve the cooling efficiency, and quickly and effectively reduce the impact of the high heat load of synchrotron radiation on the absorber. The method of opening up the water channels inside the absorber can greatly reduce the length of the welded cooling water pipe, that is, significantly reduce the welding area between the absorber and the outlet water pipe, and reduce the risk of vacuum leakage.

[0030] The transition tube is fixed to the absorber body above the absorber body by screws through the bottom boss.

[0031] The sealing flange is welded and fixed to the top of the transition pipe.

[0032] The outlet water pipe is bent and then converges vertically upwards, passing side by side through the holes on the transition pipe and the sealing flange, and is welded and fixed to the sealing flange.

[0033] The advantages of this utility model are as follows:

[0034] First, the absorber can simultaneously receive high-power-density, small-spot synchrotron radiation emitted by the undulator insert, high-power, large-spot synchrotron radiation emitted by the oscillator, and monochromatic synchrotron radiation with a certain positional offset, thus having a wide range of applications.

[0035] Secondly, this absorber moves up and down in the vertical direction to turn the synchrotron radiation light on and off. The light-receiving surface of this absorber is composed of multiple inclined planes at different angles. The multiple inclined planes are connected in sequence to form a segmented design of the light-receiving surface, which effectively shortens the length of the absorber and saves space on the beamline.

[0036] Third, the absorber is equipped with two independent cooling water channels, with multiple channels arranged in parallel at equal intervals. The inlet and outlet of the cooling water channels are welded with water outlet pipes to lead out the cooling water. This cooling scheme has a large cooling area, which can greatly improve the cooling efficiency, reduce the impact of the high heat load of synchrotron radiation on the absorber, and also significantly reduce the welding area between the absorber and the water outlet pipes, thus reducing the risk of vacuum leakage.

Detailed Implementation

[0042] The present invention will now be described in further detail with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0043] In the description of this utility model, it should be understood that the terms "upper", "lower", "horizontal", "vertical", "horizontal", "vertical", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate that the device or element referred to must have a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0044] like Figure 1 The illustration shows a lifting absorber with dual inserts according to an embodiment of this utility model. It mainly includes an absorber body 1, a water outlet pipe 2, a transition pipe 3, a sealing flange 4, and a sealing plug 5. The transition pipe 3 is fixed to the absorber body 1 with screws via a bottom boss. The sealing flange 4 is fixed to the transition pipe 3 by welding. The water outlet pipe 2 consists of two inlet pipes and two outlet pipes, all welded to the cooling water inlet and outlet positions on the upper surface of the absorber body 1. After being bent, the water outlet pipe 2 converges vertically upwards and passes side-by-side through holes in the transition pipe 3 and the sealing flange 4. The water outlet pipe 2 is welded to the sealing flange 4.

[0045] like Figure 2 As shown, the absorber body 1 is used to receive high-power-density, small-spot synchrotron radiation emitted by the undulator insert, high-power, large-spot synchrotron radiation emitted by the oscillator, and low-power synchrotron monochromatic radiation with a certain positional offset. The synchrotron white light and the synchrotron monochromatic light are parallel along the optical axis in the same vertical plane, and the synchrotron monochromatic light is vertically 25mm above the synchrotron white light.

[0046] The lower and front surfaces of the absorber body 1 are the light-receiving surfaces for receiving synchrotron radiation. The light-receiving surfaces are inclined planes with multiple different angles to the synchrotron radiation along the optical axis. The multiple inclined planes are connected in sequence to form a segmented design of the light-receiving surface, which can effectively shorten the length of the absorber body and save space occupied by the beamline.

[0047] The tilt angle of the light-receiving surface of the absorber body 1 along the optical axis relative to the synchrotron radiation is determined by the surface power density distribution of the insert light source at the corresponding inclined surface position. The length and width of each light-receiving surface are determined by the spot size of the insert light source at the light-receiving position on the light-receiving surface.

[0048] The length of the absorber body 1 along the optical axis is determined by the sum of the lengths of each of the light-receiving surfaces multiplied by the cosines of the corresponding tilt angles; the width of the absorber body 1 is the dimension of the absorber in the horizontal plane perpendicular to the optical axis, determined by the spot size of the synchrotron radiation light emitted by the insert light source on the light-receiving surface; the height of the absorber body 1 is the dimension of the absorber in the vertical plane perpendicular to the optical axis, calculated by the sum of the lengths of each of the light-receiving surfaces multiplied by the sines of the corresponding tilt angles, plus the offset distance between the center of the synchrotron radiation monochromatic light beam and the center of the synchrotron radiation light beam.

[0049] The light-receiving surfaces cut into the optical path vertically downwards, and are defined as the first light-receiving surface 11, the second light-receiving surface 12, and the third light-receiving surface 13 in the order of cutting into the optical path and receiving synchrotron radiation.

[0050] The first light-receiving surface 11, the second light-receiving surface 12, and the third light-receiving surface 13 are all symmetrical about the center of the optical axis. The first light-receiving surface 11 has a small angle with the synchrotron radiation along the optical axis and is used to receive the entire area of ​​the high-power-density, small-spot synchrotron white light emitted by the undulator insert or the central area of ​​the high-total-power, large-spot synchrotron white light emitted by the oscillator insert. The second light-receiving surface 12 has the second smallest angle with the synchrotron radiation along the optical axis and is used to receive the area other than the central area of ​​the high-total-power, large-spot synchrotron white light. The third light-receiving surface 13 has a large angle with the synchrotron radiation along the optical axis (because the thermal load of synchrotron monochromatic light is small, the angle has little effect on the surface power density distribution of the third light-receiving surface 13; 90 degrees can be selected for manufacturing convenience) and is used to receive synchrotron monochromatic light.

[0051] This segmented design of the light-receiving surface enables the absorber to simultaneously receive high-power-density, small-spot synchrotron white light, high-power, large-spot synchrotron white light, and low-power synchrotron monochromatic light, while effectively shortening the length of the absorber and saving space on the beamline.

[0052] like Figure 3 Horizontal and vertical sectional views of the cooling water channel structure Figure 4 As shown in the top view of the cooling water channel structure, two independent cooling water channels are set inside the absorber body 1, parallel to the first light-receiving surface 11 which bears the most heat load and at a certain distance from the first light-receiving surface 11. The distance between the cooling water channel and the first light-receiving surface is 16 mm, which is calculated by finite element thermal analysis.

[0053] The cooling channels are circular channels. The first cooling channel 14 and the second cooling channel 15 have the same structure, are independent of each other, and are symmetrically distributed along the optical axis. The first cooling channel 14 is formed by two transverse cooling channels, three longitudinal channels, and two vertical channels intersecting and connected in pairs perpendicularly. From the rear end surface of the absorber body 1, the first longitudinal cooling channel 143, the second longitudinal cooling channel 144, and the third longitudinal cooling channel 145 are drilled to a certain depth, and these three longitudinal channels are arranged at equal intervals. From the outer side of the absorber body 1 near both ends, the first transverse cooling channel 141 is drilled to the opposite side, penetrating the second longitudinal cooling channel 144 and the third longitudinal cooling channel 145. The second transverse cooling channel 142 is drilled to penetrate the first longitudinal cooling channel 143 and the second longitudinal cooling channel 144. From the upper surface of the absorber body 1, at the position corresponding to the first longitudinal cooling channel 143 near the rear end of the absorber... A first vertical cooling water channel 146 is constructed downwards, connecting with the first longitudinal cooling water channel 143 to form an inlet 16 for the first channel. From the upper surface of the absorber body 1, near the front end of the third longitudinal cooling water channel 145, a second vertical cooling water channel 147 is constructed downwards, connecting with the third longitudinal cooling water channel 145 to form an outlet 17 for the first channel. Four water outlet pipes 2 are welded at the inlet 16 and outlet 17 of the absorber body 1. Sealing plugs 5 are welded to the ends of the remaining circular channels on the surface of the absorber body 1, thus forming a series of cooling water channels. The second cooling water channel 15 is arranged in the same way as the first cooling water channel 14.

[0054] The design of the absorber body 1 with two independent cooling water channels inside allows three longitudinal cooling water channels to be evenly distributed above the first light-receiving surface 11, which can effectively remove the heat of the high heat load synchrotron radiation light, greatly improve the cooling efficiency, and quickly and effectively reduce the impact of the high heat load of synchrotron radiation on the absorber. The method of opening up the water channels inside the absorber can greatly reduce the length of the welded cooling water pipe, that is, significantly reduce the welding area between the absorber and the outlet water pipe, and reduce the risk of vacuum leakage.
