Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of synchrotron radiation technology relates to a kind of slot cut type absorber for the composite use condition of synchrotron radiation beam line. BACKGROUND

[0002] Synchrotron radiation device is a large infrastructure generated by electron synchrotron accelerator, using synchrotron radiation light. Synchrotron radiation light has high brightness, wide band, narrow pulse and high collimation, which makes it widely used in various scientific fields. With the continuous development of synchrotron radiation source technology, the beam intensity is greatly improved, which leads to a significant increase in light source brightness and power density, and puts forward new challenges to the heat bearing capacity and cooling structure of the main light blocking elements on the synchrotron radiation beam line.

[0003] Absorber is a key component of light blocking element, which is placed in the light path by different mechanical structures to realize the opening, closing or blocking of synchrotron radiation light, so as to determine whether the synchrotron radiation light passes through and leads to the experiment station. When the absorber closes or blocks the light, how to effectively handle the heat load received by it becomes an important challenge.

[0004] The existing absorber of light blocking element on synchrotron radiation beam line mostly adopts grazing incidence mode to receive synchrotron radiation light. Specifically, the light receiving surface that receives synchrotron radiation light is mostly smooth plane with small angle with synchrotron radiation light along the optical axis direction, which can increase the light receiving area of absorber to some extent, so as to effectively reduce the power density on the light receiving surface, and then improve the cooling effect of absorber, which is an important means to handle high heat load in synchrotron radiation device.

[0005] The absorber of light blocking element on synchrotron radiation beam line usually adopts grazing incidence mode to receive synchrotron radiation light. Although this kind of absorber structure can better withstand high heat load, such absorber is generally large in size and not directly connected with vacuum chamber sealing flange, but indirectly connected through corrugated pipe and other connecting parts, which occupies a large beam line axial space and the structure is not compact enough. SUMMARY

[0006] In view of the problems in the prior art, the utility model discloses a groove cut type absorber for the complex use condition of the synchrotron radiation beam line. The light receiving surface of the groove cut type absorber is composed of two inclined surfaces with different angles. The switching direction of the absorber is perpendicular to the beam direction, and the light receiving surface direction is parallel to the switching direction. When the absorber is cut into the light path, all the light receiving surfaces are illuminated at the same time, and the heat is evenly distributed. The absorber is not easy to be damaged. The white light light receiving surface adopts a groove cut structure, which can further increase the light receiving area and reduce the power density of the light receiving surface, so that the high heat load can be better resisted. The absorber is made of high-strength copper alloy material, and the absorber and the flange are integrally formed. The absorber has the characteristics of small size, light weight and compact structure. The absorber not only saves the space of the beam line, but also is beneficial to the design and manufacture of the whole equipment. Therefore, the manufacturing cost is greatly reduced. The cooling water channel is provided in the absorber, and the cooling water channel is provided with a water outlet pipe. The integrated absorber can greatly reduce the welding seam in the vacuum cavity and reduce the risk of leakage.

[0007] The groove cut type absorber of the application mainly includes an absorber body, a knife edge flange, a water outlet pipe and a sealing plug. One end of the absorber body is connected to the inner side of the knife edge flange, and the other end is provided with a light receiving surface. The absorber body and the knife edge flange are integrally formed by high-strength copper alloy material. The water outlet pipe includes a water inlet pipe and a water outlet pipe. The water inlet pipe and the water outlet pipe are welded to the cooling water inlet and outlet positions on the outer side of the knife edge flange. The sealing plug is welded to the back light side of the absorber body, thereby forming a cooling water circulation channel.

[0008] The irregularly shaped part of the other end of the absorber body is a key part for receiving synchrotron radiation light, which includes a first light receiving body and a second light receiving body. The first light receiving body is mainly used to receive white light with high power density. The length of the first light receiving body along the optical axis direction is determined by the spot size of the light source at the position of the absorber, the surface power density and the inner diameter of the vacuum cavity sealed by the knife edge flange. The height of the first light receiving body along the vertical direction is determined by the spot size of the light source at the position of the absorber. The thickness of the first light receiving body in the horizontal plane perpendicular to the optical axis direction is determined by the distance between the cooling water channel and the first inclined surface. The position of the cooling water channel from the light receiving surface can be calculated by finite element thermal analysis. The cooling water channel is arranged at different positions for different light sources.

[0009] The second light receiving body is mainly used to receive monochromatic light with low power density. The monochromatic light is parallel to the white light in the same horizontal plane along the optical axis direction, and the monochromatic light is horizontally offset from the white light by a certain distance. The length of the second light receiving body along the optical axis direction is determined by the spot size of the light source at the position of the absorber, the surface power density, and the inner diameter of the vacuum cavity sealed by the knife flange. The height of the second light receiving body along the vertical direction is determined by the spot size of the light source at the position of the absorber. The thickness of the second light receiving body in the horizontal plane perpendicular to the optical axis direction is determined by the distance between the synchrotron monochromatic light and the synchrotron white light along the optical axis direction and the spot size of the light source at the position of the absorber.

The segmented design of the light receiving surface can effectively shorten the length of the absorber and save the space occupied by the beamline.

[0011] The angle of the light receiving surface with the synchrotron light along the optical axis direction is determined by the surface power density distribution of the light source at the corresponding inclined surface position.

[0012] The light receiving surface of the first light receiving body is sequentially a first inclined surface and a second inclined surface along the optical axis direction from top to bottom. The light receiving surface of the second light receiving body is a third inclined surface.

The first inclined surface has a smaller angle with the synchrotron light along the optical axis direction, and is used to receive the whole area of the synchrotron white light with high power density and small spot or the central area of the synchrotron large spot with high central power density. The second inclined surface has a smaller angle with the synchrotron light along the optical axis direction, and is used to receive the area with slightly lower power density outside the central area of the synchrotron white light with high power density and large spot. The third inclined surface has a larger angle with the synchrotron light along the optical axis direction, and is used to receive the synchrotron monochromatic light with low power density and small spot.

[0015] The first inclined surface adopts a slot cutting structure, a single slot has an isosceles triangular structure with circular arc shapes of a slot top and a slot bottom, and the isosceles triangular bottom is parallel to the first inclined surface.

[0016] The shape of the slot cross section of the first inclined surface, the distance of the equidistant distribution of the multiple rows of slots, and the overall inclination angle of the multiple rows of slots are determined by the surface power density distribution of each inserted light source at the light incidence position of the first inclined surface.

[0017] Two longitudinal circular deep holes are punched from the outer end surface of the knife flange to the inside as longitudinal cooling water channels, and a horizontal circular deep hole is punched from the first light incidence body side of the absorber body to the inside as a horizontal cooling water channel.

DETAILED DESCRIPTION

[0041] The utility model will be further described in detail below in combination with the drawings, and the examples are only used to explain the utility model, and are not used to limit the scope of the utility model.

[0043] As Figure 1 The groove cutting type absorber of one embodiment of the utility model is mainly composed of an absorber body 1, a knife flange 2, a leading water pipe 3 and a sealing plug 4. One end of the absorber body 1 is connected with the inner side of the knife flange 2, and the other end is provided with a light surface. The absorber body 1 and the knife flange 2 are integrally processed and formed by using chromium-zirconium-copper material. Two leading water pipes 3 are one water inlet pipe and one water outlet pipe, which are welded at the cooling water inlet and outlet positions outside the knife flange 2. The sealing plug 4 is welded at the back light side of the absorber body 1, thereby forming a cooling water circulation channel.

[0044] As Figure 2 As shown, the irregular shape part at the other end of the absorber body 1 is a key part for receiving synchrotron radiation light, which includes a first light receiving body 11 and a second light receiving body 12.

[0045] The first light receiving body 11 is mainly used for receiving white light with high power density. The length of the first light receiving body 11 along the optical axis direction is determined by the spot size of the insert light source at the position of the absorber, the surface power density and the inner diameter of the vacuum cavity sealed by the knife flange 2. The height of the first light receiving body 11 along the vertical direction is determined by the spot size of the insert light source at the position of the absorber. The thickness of the first light receiving body 11 in the horizontal plane perpendicular to the optical axis direction is determined by the distance between the cooling water channel and the first inclined surface 111. The position of the cooling water channel relative to the first inclined surface 111 is calculated by finite element thermal analysis. Different insert light sources have different cooling water channel positions at different positions.

[0046] The second light receiving body 12 is mainly used to receive monochromatic light with low power density. The monochromatic light is parallel to the white light in the same horizontal plane along the optical axis direction, and the monochromatic light is horizontally offset from the white light by 10 mm.

The height of the second light receiving body 12 along the vertical direction is determined by the spot size of the light source at the position of the insert light source. The thickness of the second light receiving body 12 in the horizontal plane perpendicular to the optical axis direction is determined by the distance between the synchrotron monochromatic light and the synchrotron white light along the optical axis direction and the spot size of the light source at the position of the insert light source.

[0047] The light receiving surface of the first light receiving body 11 is a slope with two different angles with the synchrotron light along the optical axis direction. The light receiving surface of the second light receiving body 12 is a slope with a certain angle with the synchrotron light along the optical axis direction, and the segmented design of the light receiving surface is formed by connecting multiple slopes in sequence, which can effectively shorten the length of the absorber and save the space occupied by the beamline.

[0048] The inclination angle of the light receiving surface along the optical axis direction with the synchrotron light is determined by the surface power density distribution of the light source at the corresponding slope position.

[0049] The light receiving surface of the first light receiving body 11 is a slope with two different angles with the synchrotron light along the optical axis direction. The light receiving surface of the second light receiving body 12 is a slope with a certain angle with the synchrotron light along the optical axis direction, and the segmented design of the light receiving surface is formed by connecting multiple slopes in sequence, which can effectively shorten the length of the absorber and save the space occupied by the beamline.

[0050] The light receiving surface of the second light receiving body 12 is a third slope.

[0052] The first inclined surface 111, the second inclined surface 112 and the third inclined surface 121 are all symmetrical about the optical axis center. The first inclined surface 111 has a smaller angle with the synchrotron radiation light along the optical axis direction, and is used to receive the whole area of the synchrotron radiation white light with a higher power density and a smaller spot or the central area of the synchrotron radiation large spot with a high central power density. The second inclined surface 112 has a smaller angle with the synchrotron radiation light along the optical axis direction, and is used to receive the area with a slightly lower power density outside the central area of the synchrotron radiation white light with a high power density and a large spot, and simultaneously serves as the occupying space of the cutter when milling the groove. The third inclined surface 121 has a larger angle with the synchrotron radiation light along the optical axis direction (the slope can be 82 degrees to 110 degrees), and is used to receive the synchrotron radiation monochromatic light with a lower power density and a smaller spot.

[0053] As shown in Figure 3 the front view of the first inclined surface 111, Figure 4 the side view of the first inclined surface 111, the first inclined surface 111 adopts a groove cutting structure, and the single slotted cross section is an isosceles triangle structure with circular arcs at the groove top and the groove bottom. The isosceles triangle base is parallel to the first inclined surface 111. The single slotted whole is in the form of an isosceles triangular prism, wherein the isosceles triangular prism top edge is the groove top 111a, the isosceles triangular prism bottom edge is the groove bottom 111b, and the groove top 111a and the groove bottom 111b are both milled into circular arc shapes by a milling cutter. The multiple rows of slotted grooves are equidistantly distributed, and the multiple rows of slotted grooves are inclined at a certain angle as a whole, further increasing the light receiving area and reducing the light receiving surface power density, so that the high heat load can be better resisted.

[0054] The slotted cross section shape of the first inclined surface 111, the equidistant distribution distance of the multiple rows of slotted grooves and the overall inclination angle of the multiple rows of slotted grooves are determined by the surface power density distribution of each inserted light source at the light receiving position.

[0055] As shown in Figure 5 two longitudinal circular deep holes are punched from the outer end surface of the cutter flange 2 to the inside as longitudinal cooling water channels 14, and a transverse circular deep hole is punched from the position close to the top surface of the right side of the first light receiving body 11 of the absorber body 1 to the inside as a transverse cooling water channel 13. The longitudinal cooling water channels 14 and the transverse cooling water channel 13 are connected in series in the absorber body 1.
