Description

Technical Field

[0001] The utility model relates to the field of particle accelerator equipment, in particular to a Faraday cage with a cooling structure. Background Art

[0002] The Faraday cup is a device used to measure the intensity of a charged particle beam. Its principle is to intercept a charged particle beam and collect its charge, and then measure its current to obtain the current intensity. When the Faraday cup collects a charged particle beam, a large amount of heat will be generated, and the Faraday cup needs to be cooled to ensure its normal operation. The tip of the Faraday cup begins to sputter after being hit by the incident particle, and most of the reflected particles of the sputtered secondary electrons will be received by the inner wall of the cup, so that the reflected particles can be completely collected by the Faraday cup, which can reduce the measurement error. Therefore, a large amount of heat will be generated at the tip of the Faraday cup and on the inner wall of the cup.

[0003] The cooling channel in the existing Faraday cage only passes through the end or side wall of the Faraday cage, and the heat generation area circulated by the cooling channel is small, resulting in problems such as low heat dissipation efficiency.

[0004] Furthermore, when the existing cooling channel flows along the side wall of the Faraday cage, the cooling liquid is easily accumulated in the cooling channel due to its small thickness and large area, which is a flat channel. This leads to uneven heat dissipation, which further reduces the contact area between the cooling structure and the heat source. In particular, the cooling liquid mainly flows along the radial direction of the Faraday cage during its flow, which also leads to problems such as low heat dissipation efficiency.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] See also Figure 1-Figure 9 The utility model discloses a Faraday cup with a cooling structure, comprising: a Faraday cup body 10, the Faraday cup body 10 comprising a barrel 101 and a tip 102, one end of the barrel 101 is provided with the tip 102; a cooling channel 20, the cooling channel 20 comprising a first channel 201 and a second channel 202, the first channel 201 and the second channel 202 are connected to each other, the barrel 101 is provided with the first channel 201, and the tip 102 is provided with the second channel 202.

[0038] Therefore, in the utility model, a first flow channel 201 is provided on the cylinder 101, and the first flow channel 201 is used to dissipate heat to the cylinder 101. A second flow channel 202 is provided on the tip 102, and the second flow channel 202 is used to dissipate heat to the tip 102. The contact area with the Faraday cage body 10 is increased by the first flow channel 201 and the second flow channel 202. The cooling flow channel 20 in the utility model has a simple structural design, and the cooling flow channel 20 flows through more heating areas, thereby improving the heat dissipation efficiency.

[0039] In the embodiment of the utility model, the cylinder 101 has an annular side wall, and the first flow channel 201 is arranged along the annular side wall of the cylinder 101 .

[0040] Specifically, in order to reduce the difficulty of processing, the cylinder 101 is made in parts. After the first flow channel 201 is processed on the cylinder 101 from top to bottom, the first flow channel 201 is closed by the cover plate 1011. Of course, in other embodiments, other processing methods can also be used, and are not limited to this.

[0041] In the embodiment of the present utility model, refer to Figure 4-Figure 6 The Faraday cage with a cooling structure includes a first partition 30 and a second partition 40. The upper end of the first partition 30 is provided with a first through hole 50, and the lower end of the second partition 40 is provided with a second through hole 60. The first partition 30 and the second partition 40 are alternately arranged, and the first partition 30 and the second partition 40 are longitudinally inserted in the first flow channel 201, so that the first flow channel 201 is formed into a disc-shaped flow channel.

[0042] Specifically, at least one first baffle 30 and at least one second baffle 40 are provided, and the number of the first baffle 30 and the second baffle 40 provided depends on the actual situation; the first through holes 50 and the second through holes 60 are alternately arranged up and down, so that the coolant flows in an "S" shape up and down along the disc-shaped flow channel.

[0043] In this way, the coolant flows in the first flow channel 201 along the radial direction of the cylinder 101 and the axial direction of the cylinder 101. The flow velocity of the coolant at various locations in the first flow channel 201 is evenly distributed, which can avoid the coolant flowing slowly or even not flowing, and is beneficial to the heat dissipation of the cylinder 101.

[0044] In the embodiment of the present invention, the tip 102 is a conical tip 102 .

[0045] In the embodiment of the present utility model, refer to Figure 5 as well as Figure 7 The second flow channel 202 is arranged along the conical tip 102, and the second flow channel 202 is a "V"-shaped flow channel.

[0046] Since the tip 102 receives a relatively concentrated beam during operation of the Faraday cup, the temperature of the tip 102 is higher than that of the cup body 101 . The “V”-shaped flow channel is beneficial to the heat dissipation of the tip 102 , thereby effectively improving the heat dissipation efficiency there.

[0047] In the present invention, the cooling channel 20 can avoid liquid pressure accumulation by providing the first channel 201 and the second channel 202, and can also increase the contact area between the coolant and the heat source, thereby improving the overall heat dissipation efficiency of the Faraday cage.

[0048] In the embodiment of the present invention, the tip 102 is disposed inside the barrel 101 .

[0049] It can be understood that the cylinder 101 has a cavity inside, and the tip 102 is extended from one end of the cylinder 101 to the inner cavity of the cylinder 101, and the tip 102 is coaxially arranged with the cylinder 101. In this way, the utility model is not only conducive to realizing the function of the Faraday cage itself to collect reflected particles, but also, compared with the prior art in which the tip 102 is arranged outside the cylinder 101, the structure of the utility model reduces the space occupied by the Faraday cage, and the structure is more compact.

[0050] In the embodiment of the present invention, the Faraday cage body 10 is made of oxygen-free copper. Since oxygen-free copper has a high electrical conductivity, it is particularly suitable for use in a Faraday cage.

[0051] In the embodiment of the utility model, one end of the first flow channel 201 is the first water inlet end 2011, the other end of the first flow channel 201 is the first water outlet end 2012, one end of the second flow channel 202 is the second water inlet end 2021, and one end of the second flow channel 202 is the second water outlet end 2022; the first water inlet end 2011 and the second water inlet end 2021 are close to each other and connected to each other, and the first water outlet end 2012 and the second water outlet end 2022 are close to each other and connected to each other.

[0052] In the embodiment of the utility model, a water inlet pipe 70 and a water outlet pipe 80 are provided on the Faraday cup body 10 . The water inlet pipe 70 is connected to the first water inlet end 2011 and the second water inlet end 2021 , and the water outlet pipe 80 is connected to the first water outlet end 2012 and the second water outlet end 2022 .

[0053] Preferably, the water inlet pipe 70 and the water outlet pipe 80 are both arranged at the upper part of the cylinder 101. In other embodiments, the water inlet pipe 70 and the water outlet pipe 80 may also be arranged at the lower part of the cylinder 101. The specific setting positions of the water inlet pipe 70 and the water outlet pipe 80 are based on being able to cooperate with the first partition plate 30 and the second partition plate 40 to form a disc-shaped flow channel.

[0054] Specifically, a baffle 90 is provided on the Faraday cup body 10, and the baffle 90 is provided between the water inlet pipe 70 and the water outlet pipe 80. The baffle 90 blocks the first water inlet end 2011 and the first water outlet end 2012, and the baffle 90 blocks the second water inlet end 2021 and the second water outlet end 2022; in this way, the coolant needs to completely pass through the first flow channel 201 and the second flow channel 202 before flowing out of the water outlet pipe 80, so as to avoid the coolant flowing out of the water outlet pipe 80 without entering the first flow channel 201 and the second flow channel 202, thereby ensuring the heat dissipation efficiency and avoiding the local overheating or local overcooling of the Faraday cup body 10 due to uneven heat dissipation.

[0055] When liquid is injected, the coolant enters the cooling channel 20 through the water inlet pipe 70, and the coolant is divided into two at the first water inlet end 2011 and the second water inlet end 2021. Part of the coolant enters the first channel 201 through the first water inlet end 2011 to exchange heat with the cylinder 101, thereby achieving heat dissipation of the cylinder 101; the remaining part of the coolant enters the second channel 202 through the second water inlet end 2021 to exchange heat with the tip 102, thereby achieving heat dissipation of the tip 102.

[0056] When discharging the coolant, the coolant flows along the first flow channel 201 and the second flow channel 202, and the coolant merges into one at the first water outlet end 2012 and the second water outlet end 2022. The coolant in the first flow channel 201 enters the water outlet pipe 80 through the first water outlet end 2012, and the coolant in the second flow channel 202 enters the water outlet pipe 80 through the second water outlet end 2022, thereby realizing the discharge of the coolant.

[0057] In this way, the coolant can flow in the first flow channel 201 and the second flow channel 202 in a directional manner, thereby ensuring the heat exchange efficiency of the coolant.

[0058] In the embodiment of the utility model, the water inlet pipe 70 and the water outlet pipe 80 are both ceramic pipes.

[0059] Since the ceramic tube itself has insulating properties, the Faraday cage body 10 is insulated from external devices.

[0060] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
