As shown in fig. 1, the beam window structure 1000 is provided in the embodiment, and can be applied to an accelerator device to isolate different atmosphere environments. For example, the beam window structure 1000 may be used in a waste beam barrel in an accelerator apparatus for isolating and protecting a high vacuum environment.

As shown in fig. 1, the beam window structure 1000 may include a first flange 110, a second flange 120, and a beam window 300.

The beam window 300 may be disposed at one side of the second flange 120. The first flange 110 may be connected to a side of the second flange 120 near the beam window 300, and may press the beam window 300 against the second flange 120 to fix the beam window 300. That is, the bundle window 300 may be fixed between the first flange 110 and the second flange 120.

Referring to fig. 6 again, it will be appreciated that the first flange 110 may be provided with a first flange hole 113, and the second flange 120 may be provided with a second flange hole 126. The first flange hole 113 is coaxially opposite to the second flange hole 126. The beam window 300 may be positioned between the first flange hole 113 and the second flange hole 126 and isolate the first flange hole 113 and the second flange hole 126.

In an embodiment, a water cooling channel 112 is further configured in the first flange 110 for cooling water to pass through. The water cooling passage 112 may be provided at a circumferential side of the first flange hole 113.

During operation, when the particle beam passes through the beam window 300, for example, when the electron beam passes through the beam window 300, part of the electron beam may be deposited on the surface of the beam window 300 due to the blocking effect of the beam window 300, resulting in an increase in the temperature of the beam window 300. In an embodiment, the water cooling channel 112 is integrated in the first flange 110, and the first flange 110 may be in direct contact with the beam window 300. Therefore, the heat in the beam window 300 can be transferred to the cooling water in the water cooling channel 112 through the first flange 110 and taken away by the cooling water, so as to realize real-time cooling of the beam window 300, reduce heat accumulation at the position of the beam window 300, and avoid the influence on the normal operation of the accelerator device due to overhigh temperature of the beam window 300.

It can be appreciated that in the embodiment, the water cooling channel 112 is integrated with the first flange 110, and the first flange 110 and the second flange 120 cooperate to fix the beam window 300, and meanwhile, the beam window 300 and the water cooling structure can be connected. In one aspect, the overall structure of the beam window structure 1000 may be simplified, reducing the cost of the beam window structure 1000. On the other hand, the heat of the beam window 300 is directly transferred to the cooling water through the first flange 110, so that the heat transfer path from the beam window 300 to the cooling water can be shortened, and the heat dissipation efficiency of the beam window 300 can be improved. Meanwhile, the beam window 300 is fixed by the first flange 110 and the second flange 120, so that the beam window 300 can be conveniently replaced later.

As shown in fig. 1 and 6, in some embodiments, the water cooling channel 112 may be formed on a side of the first flange 110 away from the second flange 120. The water cooling channel 112 may be disposed around the first flange hole 113, and has a substantially non-closed annular structure. In addition, a side of the water cooling channel 112 away from the second flange 120 may be an opening structure 1121.

The beam window structure 1000 further includes a cover plate 510, a first water-cooled tube 521, and a second water-cooled tube 522. The cover plate 510 may cover the opening 1121 of the water cooling channel 112 and be welded to the first flange 110. In an embodiment, the cover plate 510 may close the opening structure 1121 of the water cooling channel 112. In some embodiments, the thickness of the cover plate 510 may be set to 3mm to 5mm. Illustratively, the thickness of the cover plate 510 may be set to any other value of 3mm, 3.2mm, 3.5mm, 3.8mm, 4.1mm, 4.5mm, 4.7mm, 5mm, or 3 mm-5 mm.

The first water-cooling pipe 521 and the second water-cooling pipe 522 may be fixedly connected to the side of the cover plate 510 away from the first flange 110 by welding. And the first water-cooling pipe 521 and the second water-cooling pipe 522 can be communicated with the water-cooling channel 112 through the through holes on the cover plate 510. In addition, the first water-cooling pipe 521 may be disposed near one end of the water-cooling passage 112, and the second water-cooling pipe 522 may be disposed near the other end of the water-cooling passage 112. In an embodiment, the first water cooling pipe 521 may be used as a cooling water input pipe for inputting cooling water into the water cooling passage 112. The second water cooling pipe 522 may serve as a cooling water output pipe for cooling water to be output from the water cooling passage 112.

In use, relatively low temperature cooling water may be introduced into the water cooling passage 112 of the first flange 110 through the first water cooling pipe 521. After reaching the water cooling channel 112, the cooling water can exchange heat with the first flange 110, so that heat at the position of the beam window 300 can be taken away, and real-time heat dissipation of the beam window 300 is realized. The cooling water may be warmed up as the heat exchange proceeds, and the cooling water having a relatively high temperature may be outputted from the water cooling passage 112 through the second water cooling pipe 522.

Referring to fig. 2 and fig. 3, in some embodiments, a sinking groove 121 is formed on a side of the second flange 120 close to the first flange 110, and the sinking groove 121 may be recessed in a direction away from the first flange 110. In addition, the countersink 121 may be disposed around the second flange hole 126, and form a closed circular groove. In addition, a side of the sink 121 near the second flange hole 126 may be opened, so that the sink 121 may communicate with the second flange hole 126. In an embodiment, the circumferential edge of the beam window 300 may extend into the countersink 121.

In some embodiments, the beam window 300 may be circular. Correspondingly, the contour of the side of the countersink 121 away from the second flange hole 126 may also be circular and match the beam window 300. In addition, the inner diameter of the sinking groove 121 may be slightly larger than the outer diameter of the beam window 300, so that the beam window 300 can be smoothly installed in the sinking groove 121, and the circumferential limit of the beam window 300 can be realized. In some embodiments, the inner diameter of the countersink 121 may be 1mm to 2mm larger than the outer diameter of the beam window 300. Illustratively, the inner diameter of the sink 121 may be 1mm, 1.2mm, 1.35mm, 1.5mm, 1.6mm, 1.75mm, 1.9mm, 2mm, or any other value from 1mm to 2mm greater than the outer diameter of the beam window 300.

As shown in fig. 2, 3 and 6, a second sealing ring 220 is disposed between the second flange 120 and the bundle window 300. It is understood that one side of the second sealing ring 220 may abut against the second flange 120, and the other side of the second sealing ring 220 may abut against the beam window 300. The second sealing ring 220 can seal between the second flange 120 and the beam window 300 to prevent air leakage, and can seal the connection position of the first flange 110 and the second flange 120. In some embodiments, the second seal ring 220 may be made of an aluminum magnesium alloy.

In some embodiments, the second flange 120 further has an annular assembly groove 122 formed on a side thereof adjacent to the first flange 110, and the assembly groove 122 may be disposed around a peripheral side of the second flange hole 126 and on a side of the countersink 121 adjacent to the second flange hole 126.

In an embodiment, the fitting groove 122 may be recessed away from the beam window 300 with respect to the groove bottom of the sinking groove 121, and the opening of the fitting groove 122 may be engaged with the groove bottom of the sinking groove 121. The second seal ring 220 may be disposed in the assembly groove 122, and there may be an assembly groove 122 to provide radial limitation for the second seal ring 220, so as to prevent the second seal ring 220 from moving randomly relative to the second flange 120 and the beam window 300 to affect the sealing effect.

The fitting groove 122 may include a first sidewall 1221, a bottom wall 1222, and a second sidewall 1223. Wherein the bottom wall 1222 may be opposite to the beam window 300, the first side wall 1221 is located on a side of the bottom wall 1222 near the second flange hole 126, and the second side wall 1223 is located on a side of the bottom wall 1222 away from the second flange hole 126. In addition, a gap may exist between the second sealing ring 220 and the second side wall 1223, and the gap size may be set between 0.2mm and 0.4mm, so that a sufficient deformation space may be provided for the second sealing ring 220. Illustratively, the gap size between the second seal ring 220 and the second sidewall 1223 may be set to 0.2mm, 0.25mm, 0.3mm, 0.32mm, 0.36mm, 0.4mm, or any other value from 0.2mm to 0.4 mm.

In some embodiments, the first sidewall 1221 may be inclined relative to the axial direction of the beam window structure 1000. The axial direction of the beam window structure 1000 may refer to the extending direction of the axis L. Specifically, the first side wall 1221 gradually slopes in a direction approaching the axis L of the beam window structure 1000 from an end away from the beam window 300 to an end approaching the beam window 300.

With reference to fig. 5, the first side wall 1221 may form an angle α with the bottom wall 1222, where α is an obtuse angle, and 120 ° is equal to or greater than α is equal to or less than 150 °. In one aspect, the second sealing ring 220 may be conveniently installed in the assembly groove 122, and the expansion direction of the second sealing ring 220 may be guided when the second sealing ring 220 is pressed, so that the second sealing ring 220 is centripetally expanded. On the other hand, the air in the sinking groove 121 and the assembling groove 122 can be conveniently discharged, so that the vacuum press sealing of the beam window 300 is realized. Illustratively, the angle α between the first side wall 1221 and the bottom wall 1222 may be set to any of 120 °, 125 °, 128 °, 135 °, 142 °, 146 °, 150 °, or 120 ° to 150 °.

In some embodiments, the mounting groove 122 may be configured with a first axially extending along the beam window structure 1000Dimension h ₁ . When the second sealing ring 220 is not subject to external force, a second dimension h extending along the axial direction of the beam window structure 1000 can be provided ₂ ，

On the one hand, it is ensured that the second seal ring 220 protrudes with respect to the fitting groove 122, on the side close to the bundle window 300, so as to be brought into pressing abutment with the bundle window 300 to achieve sealing. On the other hand, the second seal ring 220 is securely retained in the fitting groove 122, and the second seal ring 220 is prevented from being separated from the fitting groove 122 at will. Illustratively, the mounting groove 122 has a first dimension h ₁ May be a second dimension h of the second seal ring 220 ₂ Any other value of 1/2, 7/12, 2/3 or 1/2 to 2/3.

In addition, countersink 121 may be configured with a third dimension h extending axially along beam window structure 1000 ₃ Third dimension h ₃ Not exceeding the second dimension h ₂ And the sum of half of the thickness of the beam window 300. The thickness of the beam window 300 may refer to a dimension of the beam window 300 parallel to an axial direction of the beam window structure 1000. In some embodiments, the thickness of the beam window 300 may be set to 0.8 mm-2 mm.

Further, the cross section of the second seal ring 220 parallel to the axial direction of the beam window structure 1000 may be a polygon, and the polygon includes at least four vertex angles. In some embodiments, the cross-section of the second sealing ring 220 may be regular hexagon, and accordingly, the second sealing ring 220 may include six vertex angles. One vertex of the second sealing ring 220 may abut against the bottom wall 1222 of the assembly groove 122, and the other vertex opposite thereto may abut against a side surface of the beam window 300 adjacent to the second flange 120. Thus, by pressing the second seal ring 220 with a small force, the second seal ring 220 can be deformed and sealed in contact with the beam window 300 and the bottom wall 1222 of the fitting groove 122, and the tightness between the second seal ring 220 and the beam window 300 and between the second seal ring 220 and the fitting groove 122 can be improved.

In other embodiments, the second sealing ring 220 may be configured to have a quadrilateral, pentagonal, or octagonal cross-section. One vertex angle of the second seal ring 220 is abutted against the bottom wall 1222 of the fitting groove 122, and the other vertex angle of the second seal ring 220 is abutted against a side surface of the beam window 300 near the second flange 120.

In addition, the beam window 300 can be made of beryllium, and has better mechanical properties, heat conduction performance, less energy deposition and lower air release rate, so that the beam window structure 1000 has the characteristics of high reliability and fast heat dissipation. Thus, the beam window structure 1000 can be suitably used for an accelerator device with high repetition frequency, high power and high current intensity, and the versatility of the beam window structure 1000 can be improved.

As shown in fig. 2 and 3, in some embodiments, a side of the first flange 110 adjacent to the bundle window 300 may be convexly provided with a boss 114, and an outer diameter of the boss 114 may be smaller than an outer diameter of the bundle window 300. The boss 114 may abut against a side of the beam window 300 away from the second flange 120, and may press the beam window 300 into the sink 121. The height of the boss 114 may be set to 2mm to 4mm in parallel to the axial direction of the beam window structure 1000. Illustratively, in some embodiments, the height of the boss 114 may be set to 2mm, 2.3mm, 2.6mm, 2.9mm, 3.1mm, 3.5mm, 3.8mm, 4mm, or any other value from 2mm to 4mm.

As shown in fig. 1 and 6, a first set of bolt holes 111 is formed in the first flange 110, and the first set of bolt holes 111 may be annularly distributed along the circumferential direction of the first flange 110. The second flange 120 may be provided with a second set of bolt holes 123, and the second set of bolt holes 123 may be annularly distributed along the circumferential direction of the second flange 120 and located at a side of the countersink 121 away from the assembly groove 122. In addition, the second group of bolt holes 123 do not interfere with the countersink 121, and the edge of the side of the second group of bolt holes 123 close to the countersink 121 is spaced from the edge of the side of the countersink 121 far from the second flange hole 126, and the spacing gap can be set to be 2 mm-4 mm. Illustratively, in some embodiments, the spacing gap between the side edge of the second set of bolt holes 123 proximate to the countersink 121 and the side edge of the countersink 121 distal to the second flange hole 126 may be set to 2mm, 2.3mm, 2.5mm, 2.8mm, 3.1mm, 3.5mm, 3.7mm, 4mm, or any other value from 2mm to 4mm.

The first set of bolt holes 111 includes the same number of bolt holes as the second set of bolt holes 123, and are in one-to-one correspondence. The first flange 110 and the second flange 120 may be fixedly connected by bolts, and the bolts may sequentially pass through corresponding bolt holes in the first set of bolt holes 111 and the second set of bolt holes 123.

In an embodiment, the first set of bolt holes 111 and the second set of bolt holes 123 each comprise at least 16 bolt holes. Thus, tight connection between the first flange 110 and the second flange 120 can be ensured, and pressure sealing of each part of the circumference of the bundle window 300 can be ensured, thereby preventing air leakage. For example, the first set of bolt holes 111 and the second set of bolt holes 123 may each comprise 16 bolt holes. In addition, the hole diameter of the bolt hole may be set to 8mm to 10mm. Illustratively, in some embodiments, the aperture of the bolt hole may be set to 8mm, 8.5mm, 9mm, 9.5mm, 10mm, or any other value from 8mm to 10mm.

In other embodiments, the first set of bolt holes 111 and the second set of bolt holes 123 may each comprise 18, 19, 20, 22, etc.
