[0024] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.
[0025] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.
[0026] Beam extraction devices are widely used in particle accelerators. In practical applications, they are often installed at the end of the accelerator, where the beam passes through the device and acts on the experimental area. However, prior art techniques for beam extraction devices, after passing through the device, continue to "fly" through the atmosphere and act on the experimental object, making them unsuitable for experiments requiring high atmospheric pressure and limiting their applicability.
[0027] In view of this, an embodiment of the present application provides an accelerator, comprising the beam extraction device 100 in any one of the following embodiments.
[0028] For example, the beam extraction device 100 may be disposed at the end of the accelerator, and the beam may enter the beam extraction device 100 through the end and be guided to act on the experimental object.
[0029] Another aspect of the present application provides a beam extraction device 100, see Figure 1 and Figure 2 The beam extraction device 100 includes a first flange 1, a second flange assembly 2, a titanium membrane 3, and an experimental device 4. The first flange 1 is formed with a first channel 1a, which is used to communicate with the accelerating chamber of the accelerator. The second flange assembly 2 is disposed at one end of the first flange 1 and is formed with a second channel 2a. The titanium membrane 3 is disposed between the first flange 1 and the second flange assembly 2 and is used to separate the first channel 1a from the second channel 2a. The experimental device 4 has an experimental chamber 4a with adjustable air pressure, which is connected to the second channel 2a, and the experimental sample is placed in the experimental chamber 4a.
[0030] The beam extraction device 100 provided in the present application is connected to the accelerator by setting a first flange 1, and the second flange assembly 2 is connected to the experimental device 4. The titanium membrane 3 is set between the first flange 1 and the second flange 22 to separate the first channel 1a and the second channel 2a, so that the first channel 1a forms a sealed structure. In this way, the accelerated beam can enter the beam extraction device 100 through the first channel 1a. The titanium membrane 3 can effectively ensure that the beam can effectively pass through and enter the experimental cavity 4a through the second channel 2a. The experimental cavity 4a of the present application has an adjustable air pressure function, so that without changing the position of the titanium membrane 3, by adjusting the air pressure of the experimental cavity 4a, the beam can act on the experimental product in an atmospheric pressure environment, a vacuum environment (such as simulating a space radiation environment) or other air pressure environments to meet different experimental needs, and has strong applicability and flexibility.
[0031] The accelerator provided in the present application is characterized by high applicability and flexibility based on the advantages of the above-mentioned beam extraction device 100 .
[0032] For example, in one embodiment, please refer to Figure 2 , the shape of the first channel 1a can be a rectangular parallelepiped.
[0033] In one embodiment, the experimental device 4 includes a housing 41 and a pump body 42 . The housing 41 forms an experimental chamber 4 a . The pump body 42 is used to adjust the air pressure in the experimental chamber 4 a .
[0034] Here, when it is necessary to simulate a vacuum environment or an environment with a certain air pressure, the adjustment can be made directly by starting the pump body 42 , which is simple to operate, easy to implement, and highly practical.
[0035] For example, in one embodiment, the pump body 42 can be provided with a barometer, an operation panel and a controller. The barometer can obtain the air pressure of the experimental chamber 4a. The barometer is communicatively connected to the controller. When it is necessary to simulate different air pressure environments, the air pressure value can be input through the operation panel. When the air pressure value obtained by the barometer reaches the set value, a stop command can be issued to the controller. After receiving the stop command, the controller can control the pump body 42 to shut down. When the barometer detects that the air pressure of the experimental chamber 4a is lower than or higher than the set value during the experiment, the pump body 42 can be automatically controlled to start or shut down, so that the air pressure value of the experimental chamber 4a can be maintained near the set value. The degree of automation is high and the air pressure environment simulation is accurate.
[0036] In one embodiment, the housing 41 further forms an opening communicating with the experimental chamber 4 a , and the experimental device 4 includes a door disposed on the housing 41 to open or close the opening.
[0037] For example, the experimental sample can be placed in the experimental chamber 4a by opening the door.
[0038] Here, by setting up a door body, when the beam needs to act on the experimental object in an atmospheric pressure environment, the door body can be opened, and the air pressure of the experimental chamber 4a can be kept consistent with the external environment through the opening; when it is necessary to simulate an environment with a certain air pressure, the opening can be closed through the door body, and then the pump body 42 can be started to quickly adjust the air pressure of the experimental chamber 4a, and the door body can also reduce the leakage of radiation to a certain extent.
[0039] For example, in one embodiment, the door body can also be connected to a controller to control the door body to open or close. In this way, when it is necessary to simulate a certain air pressure environment, the door body can be controlled to close through the controller to quickly adjust the air pressure. When the experiment is over, the door body can be controlled to open, with a high degree of automation.
[0040] In one embodiment, please refer to Figure 1 and Figure 2 The second flange assembly 2 includes a pressure plate 21 and a second flange 22 . The titanium membrane 3 is arranged between the pressure plate 21 and the first flange 1 . The second flange 22 is arranged between the experimental device 4 and the pressure plate 21 .
[0041] Here, by setting up the pressure plate 21, it can cooperate with the first flange 1 to fix and press the titanium film 3, reducing the movement or displacement of the titanium film 3 during operation, and the setting of the second flange 22 facilitates the connection of the experimental device 4, making the entire beam extraction structure compact.
[0042] Exemplarily, the pressure plate 21 and the first flange 1 can be connected by screwing. For example, a plurality of first connecting holes 21b are formed on the pressure plate 21, and a plurality of second connecting holes 1c are formed on the first flange 1. Then, a plurality of fasteners are provided, each fastener is passed through a first connecting hole 21b and a second connecting hole 1c. In this way, the connection strength between the pressure plate 21 and the first flange 1 can be improved to compress the titanium membrane 3 located therebetween.
[0043] In one embodiment, a blade is formed at one end of the first flange 1 away from the titanium film 3 along the beam guiding direction, and a copper sealing ring is provided inside the blade. In this way, the sealing performance between the accelerating chamber and the first channel 1a can be improved when connected to the accelerator.
[0044] In one embodiment, please refer to Figure 1 and Figure 2 The second flange assembly 2 includes a bellows 23 , which is connected between the second flange 22 and the pressure plate 21 .
[0045] For example, the material of the bellows 23 may be metal.
[0046] In this way, by arranging the bellows 23 between the second flange 22 and the pressure plate 21, vibration and thermal expansion or contraction of the pipeline can be absorbed during the movement of the beam, thereby improving its working stability. The bellows 23 is also convenient for connection and alignment with the second flange 22 and the pressure plate 21, thereby enhancing the flexibility of the structure.
[0047] In one embodiment, please refer to Figure 1 , the experimental device 4 is provided with a third flange 43 , and the third flange 43 is connected to the second flange 22 through a copper sealing ring.
[0048] For example, the third flange 43 may be provided on the housing 41. A knife edge may be provided on the third flange 43 or the second flange 22, and a copper sealing ring may be provided in the knife edge, and a sealing effect is achieved by squeezing the copper sealing ring in the knife edge.
[0049] Thus, by providing the third flange 43 , the experimental device 4 can be easily connected, and by providing a copper sealing ring between the third flange 43 and the second flange 22 , the sealing effect between the second channel 2 a and the experimental chamber 4 a can be improved.
[0050] In one embodiment, a first sealing ring is provided between the first flange 1 and the titanium membrane 3 , and a second sealing ring is provided between the pressure plate 21 and the titanium membrane 3 .
[0051] For example, see Figure 1 A first sealing groove 1b is provided at one end of the first flange 1 close to the titanium membrane 3, and a second sealing groove 21a is provided at one end of the pressure plate 21 close to the titanium membrane 3. The first sealing ring can be provided in the first sealing groove 1b, and the second sealing ring can be provided in the second sealing groove 21a.
[0052] Here, by providing the first sealing ring and the second sealing ring, the gaps between the titanium film 3 and the pressure plate 21 and the first flange 1 can be sealed, thereby improving the sealing effect of the beam extraction device 100 and reducing the impact on the beam.
[0053] In one embodiment, the first sealing ring and the second sealing ring are spaced apart from each other along a direction perpendicular to the guiding direction of the beam.
[0054] For example, the guiding direction perpendicular to the beam may be the radial direction of the first flange 1 , and the first sealing ring may be arranged around the outside of the second sealing ring, that is, the two will not contact each other during sealing.
[0055] Here, by arranging the first sealing ring and the second sealing ring at intervals along a direction perpendicular to the beam guiding direction, structural interference between the two during sealing can be reduced, thereby further improving the sealing effect of the beam extraction device 100 .
[0056] In one embodiment, the first sealing ring and / or the second sealing ring is a rubber sealing ring.
[0057] Illustratively, the first sealing ring may be a rubber sealing ring, or the second sealing ring may be a rubber sealing ring, or both the first sealing ring and the second sealing ring may be rubber sealing rings.
[0058] Here, the first sealing ring and / or the second sealing ring is a rubber sealing ring. On the one hand, a better sealing effect can be achieved by squeezing it; on the other hand, the rubber sealing ring can reduce damage to the titanium membrane 3 and increase the service life of the titanium membrane 3.
[0059] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, and improvements that fall within the spirit and principles of the present application are intended to be within the scope of protection of the present application.
