Description

Technical Field

[0001] This invention application belongs to the field of solid target technology, and specifically relates to an accelerator solid target device with water and helium dual cooling and its working method. Background Technology

[0002] Solid targets in accelerators are core components for nuclide production. Under the bombardment of high-energy particle beams, the target undergoes nuclear reactions to generate the desired nuclide products, widely used in nuclear physics experiments, materials science research, and medical isotope production. During operation, solid targets are subjected to intense radiation from high-energy particle beams, causing a rapid rise in surface temperature. Prolonged operation can lead to thermal damage, structural deformation, or even failure of the target material, affecting the quality and production efficiency of the nuclide products. Traditional solid target cooling methods typically employ indirect water cooling, using cooling channels on the back of the target to remove heat with cooling water. However, this method is limited by the small cooling area on the back of the target, resulting in low heat transfer efficiency and difficulty in effectively handling the high heat load generated by high-power accelerators. The cooling effect is unsatisfactory. Furthermore, traditional devices rely heavily on manual operation for loading and unloading targets. Irradiated targets retain significant amounts of residual radiation, posing a serious risk of radiation damage during manual loading and unloading, increasing the risk of operator exposure to high-radiation environments. This fails to meet the safety and automation requirements of modern high-power accelerators. Therefore, the design of solid target devices must balance efficient cooling, automated operation, and radiation protection to ensure operational stability, safety, and efficiency.

[0003] In existing technologies, some solutions attempt to address the aforementioned problems through automation and improved cooling methods. For example, invention patent application CN119172915A discloses a solid target device and operating method for accelerator isotope production: a stepper motor controls a moving slider to push the target, and the irradiated target automatically enters a shielding container through a slide, avoiding the radiation risk caused by manual operation; invention patent application CN116403753A discloses an irradiation device for a solid target system for accelerator isotope production: a cooler is connected via a vacuum-sealed flange, and a fluid refrigerant connected to an external cold source is installed inside for cooling, and an observation window or detection device with a water-cooled jacket is provided, reducing the risk of radiation damage. However, the cooling methods of these devices still mainly rely on a single liquid medium (such as cooling water), which limits the cooling efficiency and makes it difficult to meet the requirements of efficient heat dissipation for the target.

[0004] Therefore, there is an urgent need for a new type of solid target device that optimizes cooling methods, improves cooling efficiency, and enhances automation to meet the operational requirements of high-power accelerators under high heat load and high radiation environments, and to provide an efficient and safe solution for nuclide production.

[0023] To make the objectives, technical solutions, and advantages of this invention application clearer, the embodiments of this invention application will be described in further detail below with reference to the accompanying drawings.

[0024] Firstly, such as Figures 1 to 9 As shown, an accelerator solid target device with dual water and helium cooling includes: a support assembly 100, a helium cooling assembly 200, a water cooling assembly 300, multiple clamping assemblies, and multiple moving assemblies; the helium cooling assembly 200, the water cooling assembly 300, the multiple clamping assemblies, and the multiple moving assemblies are mounted on the support assembly 100; the multiple clamping assemblies clamp or release a shuttle carrying a target sheet, the clamping assemblies are connected to the moving assemblies, and the moving assemblies move the clamping assemblies; the helium cooling assembly 200 and the water cooling assembly 300 are respectively used for helium cooling cycle and water cooling cycle of the target sheet.

[0025] In some embodiments, the shuttle S may also be referred to as a target frame, target support frame, or target holder. A target frame can be understood or meant as a frame that fixes or supports the target piece; a target support frame can be understood or meant as a frame that supports the target piece, and the target support frame may have the function of moving the target piece in the solid target device, such as adjusting the position of the target piece in the support frame; a target holder can be understood or meant as a frame structure surrounding the target piece, supporting and maintaining the stability of the target piece. Those skilled in the art can understand the meaning of the shuttle according to the actual solid target device design and usage scenario, and no particular limitations are imposed on them.

[0026] In some embodiments, the support assembly 100 may employ a frame structure made of high-strength alloy material to provide a stable support platform. The support assembly 100 may support the helium-cooled assembly 200 and the water-cooled assembly 300, and the helium-cooled assembly 200, the water-cooled assembly 300, multiple clamping components and moving components may be mounted on the support assembly 100 by welding or fastening with bolts or other fasteners.

[0027] In some embodiments, the support assembly 100 may include a first A-frame 101, a second A-frame 102, and a connecting frame 103, wherein the connecting frame 103 is located on the supports of the first A-frame 101 and the second A-frame 102, and connects the first A-frame 101 and the second A-frame 102. Alternatively, the connecting frame 103 may also be a connecting rod.

[0028] In some embodiments, the helium cooling assembly 200 is mounted on the support assembly 100. The helium cooling assembly 200 may include helium gas and circulation pipelines, thereby enabling direct or indirect circulating cooling of the target.

[0029] For example, the helium cooling assembly 200 may include helium, a circulation pipeline and multiple nozzles. The circulation pipeline is connected to the multiple nozzles, which can be arranged around the target. Helium is ejected from the multiple nozzles, flows along the surface of the target to absorb heat, and is collected through a return pipeline. The return pipeline is connected to the helium circulation system, and after cooling, it is re-ejected to form a helium cooling cycle.

[0030] For example, the helium cooling assembly 200 may include a helium source, a pump, and a pipe. A circulation pipe is installed on the target plate and connected to the pipe. Multiple nozzles are installed on the shuttle and connected to the nozzles via the circulation pipe. Helium is supplied by the helium source, pumped into the pipe, and then enters the circulation pipe. The helium is ejected from the multiple nozzles, flows along the surface of the target plate to absorb heat, and is collected through a return pipe connected to the helium assembly. The collected helium is cooled and can then return to the helium assembly, allowing for reuse and thus forming a helium cooling cycle.

[0031] In some embodiments, the water-cooling component 300 is mounted on the bracket assembly 100. The water-cooling component 300 includes a water source, a water pump, and water pipes, and dissipates heat to the back of the target plate through indirect contact.

[0032] For example, a heat-conducting plate made of a high thermal conductivity material (such as copper or aluminum) is provided on the back of the target plate, and a circulating water pipe is embedded or welded to the heat-conducting plate. The circulating water pipe can be arranged in a serpentine or parallel layout. The water pipe is connected to the circulating water pipe. Cooling water is supplied by an external water source, pumped into the water pipe and then enters the circulating water pipe. After absorbing the heat of the target plate, it is cooled again. The cooling water can flow back to the water-cooling assembly to achieve water-cooling of the target plate. The cooling water can also be recycled, thus forming a water-cooling cycle.

[0033] In some embodiments, the clamping assembly may be designed as a mechanical clamp, and the clamping assembly may include jaws. Multiple clamping assemblies may include multiple jaws, and the multiple jaws may work together to securely clamp or release the shuttle carrying the target piece.

[0034] In some embodiments, the number of moving components corresponds to the number of clamping components. The moving components may be motors, lead screws, slide rails, and sliders. The sliders are connected to the moving components, and the moving components can precisely control the movement of the clamping components.

[0035] In some embodiments, multiple clamping components hold a shuttle carrying a target sheet, ensuring the target sheet is securely fixed. Then, multiple moving components move the clamping components, along with the shuttle, to the irradiation position within the accelerator beam path. During irradiation, the high-energy particle beam bombards the target sheet, causing its temperature to rise. A helium cooling component 200 cools the target sheet by injecting cryogenic helium gas, utilizing the high thermal conductivity of helium to dissipate heat. A water cooling component 300 further cools the back of the target sheet using circulating cooling water. This dual cooling mechanism effectively controls the target sheet temperature and prevents overheating damage. After irradiation, the moving components move the clamping components, along with the shuttle, out of the irradiation position. The clamping components release the shuttle, which is then returned to the hot chamber for post-processing via a blower, avoiding human contact with the radiation source.

[0036] In this invention application, a water-helium dual cooling system is used, combining the high thermal conductivity of helium and the strong cooling capacity of water to improve the heat dissipation efficiency of the target plate, meeting the high heat load requirements of high-power accelerators. The coordinated design of the clamping and moving components enables the loading, unloading, and movement of the target plate, reducing manual intervention, avoiding the risk of operators being exposed to radiation, protecting operators, and improving the safety of the solid target device. It realizes the combination of automated loading and unloading operations and dual cooling, providing an efficient and safe solution for the application of solid targets in accelerators.

[0037] Optionally, each clamping assembly includes a cylinder 601 and a gripper 602, with the cylinder 601 connected to the gripper 602. Each moving assembly includes a drive cylinder 701, a guide rail 702, a slider 703, and a support plate 704, with the cylinder 601 connected to the support plate 704, the gripper 602 rotatably connected to the support plate 704, the drive cylinder 701 connected to the slider 703, the slider 703 sliding relative to the guide rail 702, and the support plate 704 connected to the slider 703.

[0038] In some embodiments, there may be 2, 4, or 6 clamping components, and there may be 2, 4, or 6 moving components. The clamping components may be arranged symmetrically, and the moving components may be arranged symmetrically. The number of moving components is equal to the number of clamping components. The shuttle is located between the clamping components. In this way, the clamping components can jointly clamp or release the shuttle carrying the target piece. Those skilled in the art do not have any particular limitations on this.

[0039] In some embodiments, cylinder 601 is connected to support plate 704, and piston rod of cylinder 601 is hinged to gripper 602. Gripper 602 is connected to support plate 704 via connecting shaft 603, and gripper 602 is hinged to connecting shaft 603. In this way, when piston rod of cylinder 601 extends, it can drive gripper 602 to rotate; when piston rod of cylinder 601 retracts, it can also drive gripper 602 to rotate.

[0040] In some embodiments, the piston rod of the drive cylinder 701 is connected to the slider 703, the slider 703 slides relative to the guide rail 702, and the support plate 704 is connected to the slider 703. When the piston rod of the drive cylinder 701 extends, it can drive the slider 703 to slide along the guide rail 702, thereby driving the clamping assembly on the support plate 704 to move. When the piston rod of the drive cylinder 701 retracts, it can also drive the slider 703 to slide along the guide rail 702, thereby driving the clamping assembly on the support plate 704 to move.

[0041] In some embodiments, there are two clamping components, namely, the multiple clamping components include a first clamping component and a second clamping component, the first clamping component and the second clamping component have the same structure as the clamping component. There are two moving components, namely, the multiple moving components include a first moving component and a second moving component, the first moving component and the second moving component have the same structure as the moving component. The first clamping component and the second clamping component can be arranged symmetrically. The first clamping component is connected to the first moving component, and the second clamping component is connected to the second moving component. The shuttle is located between the first clamping component and the second clamping component. When the first clamping component and the second clamping component are close to each other, the first clamping component and the second clamping component can jointly clamp the shuttle carrying the target piece. When the first clamping component and the second clamping component are far apart from each other, the first clamping component and the second clamping component can jointly release the shuttle carrying the target piece.

[0042] In some embodiments, when the shuttle is in the initial position of the vacuum chamber, when the piston rod of the cylinder of the first clamping assembly extends, the jaws of the first clamping assembly rotate. When the piston rod of the cylinder of the second clamping assembly extends, the jaws of the second clamping assembly rotate. The jaws of the first clamping assembly and the jaws of the second clamping assembly jointly clamp the shuttle carrying the target plate. The drive cylinders of the first moving assembly and the second moving assembly can move the shuttle to the collimator engagement position, so that the target plate is in the irradiation position in the accelerator beam path.

[0043] In some embodiments, after the target sheet is irradiated, the drive cylinders of the first moving component and the second moving component can move the shuttle back to its initial position in the vacuum chamber. When the piston rod of the cylinder of the first clamping component retracts, the jaws of the first clamping component rotate. When the piston rod of the cylinder of the second clamping component retracts, the jaws of the second clamping component rotate. The jaws of the first clamping component and the jaws of the second clamping component together release the shuttle carrying the target sheet.

[0044] Optionally, the helium-cooled assembly 200 includes a first cylinder, a gas pipe, a gas pipe connector, and a first support frame. The first support frame connects the first cylinder and the support assembly, and the gas pipe connects to the gas pipe connector. The first cylinder drives the gas pipe to move. The water-cooled assembly 300 includes a second cylinder, a water pipe, a water pipe connector, and a second support frame. The second support frame connects the second cylinder and the support assembly, and the water pipe connects to the water pipe connector. The second cylinder drives the water pipe to move.

[0045] In some embodiments, after the shuttle moves to the irradiation position in the accelerator beam path, the circulation pipeline is set on the target plate, the first cylinder on the first support frame drives the air pipe to move (e.g., the air pipe moves up and down), the air pipe connector is connected to the circulation pipeline, thus realizing the connection of the circulation pipeline to the air pipe, multiple nozzles are set on the target plate, the circulation pipeline is connected to the nozzles, helium is supplied by a helium source, and after being sent into the air pipe by the air pump, it enters the circulation pipeline, and helium is ejected from multiple nozzles.

[0046] In some embodiments, a heat-conducting plate is provided on the back of the target plate, and a circulating water pipe is embedded or welded to the heat-conducting plate. The circulating water pipe can be arranged in a serpentine or parallel layout. The second cylinder on the second support frame drives the water pipe to move (e.g., the water pipe moves up and down). The water pipe joint is connected to the circulating water pipe, thus realizing the connection of the water pipe to the circulating water pipe. Cooling water is supplied by an external water source and is pumped into the water pipe and then enters the circulating water pipe.

[0047] Optionally, the clamping assembly also includes a limiting block that limits the shuttle.

[0048] In some embodiments, the limiting blocks of multiple clamping components can limit the shuttle, thereby allowing multiple grippers to jointly clamp the target.

[0049] Optionally, the water-helium dual-cooled accelerator solid target device also includes a vacuum chamber 400, a collimator 500, and a blower 401. The blower 401 is connected to the vacuum chamber 400. The collimator 500 is installed inside the vacuum chamber 400 and cooperates with the shuttle. Multiple clamping components and multiple moving components are also installed inside the vacuum chamber 400.

[0050] In some embodiments, the shuttle can move on a slide or guide rail within the vacuum chamber to allow the target to enter the vacuum chamber. The shuttle is in its initial position within the vacuum chamber, and multiple clamping components can jointly clamp the shuttle carrying the target. Specifically, the grippers of the multiple clamping components can jointly clamp the shuttle carrying the target. After the shuttle is clamped, multiple moving components can move the shuttle to engage with the collimator. Specifically, the drive cylinders of the multiple moving components can move the shuttle to engage with the collimator, so that the target is positioned at the irradiation position in the accelerator beam path.

[0051] For example, the grippers of the first clamping component and the second clamping component can jointly clamp the shuttle carrying the target sheet. After the shuttle is clamped, the drive cylinders of the first moving component and the second moving component can move the shuttle to the collimator to engage, so that the target sheet is in the irradiation position in the accelerator beam path.

[0052] In some embodiments, blower 401 ( Figures 5 to 7(This is for reference only) The shuttle is moved on the slide or guide rail inside the vacuum chamber by airflow. Of course, a traction device or moving device can also be used to move the shuttle on the slide or guide rail inside the vacuum chamber, so that the target plate enters the vacuum chamber and the shuttle is in the initial position of the vacuum chamber. Similarly, multiple clamping components can jointly clamp the shuttle carrying the target plate. Specifically, the jaws of multiple clamping components can jointly clamp the shuttle carrying the target plate. After the shuttle is clamped, multiple moving components can move the shuttle so that it cooperates with the collimator. Specifically, the drive cylinders of multiple moving components can move the shuttle so that it cooperates with the collimator, so that the target plate is in the irradiation position in the accelerator beam path.

[0053] In some embodiments, after the target sheet irradiation is completed, the helium cooling assembly 200 and the water cooling assembly 300 stop performing helium cooling and water cooling cycles on the target sheet, respectively. Multiple moving components drive the shuttle back to its initial position in the vacuum chamber. Specifically, the drive cylinders of the multiple moving components drive the shuttle back to its initial position in the vacuum chamber. Multiple clamping components jointly release the shuttle carrying the target sheet. Specifically, the grippers of the multiple clamping components jointly release the shuttle carrying the target sheet. A blower delivers airflow, pushing the shuttle along the return slide or guide rail to the hot chamber inlet. The sealing valve closes, and the robotic arm inside the hot chamber can perform target sheet disassembly, inspection, or storage. Alternatively, a traction device or moving device can be used to push the shuttle along the return slide or guide rail to the hot chamber inlet.

[0054] For example, after the target sheet is irradiated, the helium cooling assembly 200 and the water cooling assembly 300 stop performing helium cooling and water cooling cycles on the target sheet, respectively. The drive cylinders of the first moving assembly and the second moving assembly drive the shuttle back to its initial position in the vacuum chamber. The grippers of the first clamping assembly and the second clamping assembly release the shuttle carrying the target sheet. The blower delivers airflow, pushing the shuttle along the return slide or guide rail to the hot chamber inlet. The sealing valve closes, and the robot inside the hot chamber can perform target sheet disassembly, inspection, or storage.

[0055] Secondly, such as Figure 10 As shown, a method for operating a water-helium dual-cooled accelerator solid target device, employing or not employing one of the water-helium dual-cooled accelerator solid target devices described in the first aspect above, includes: The shuttle is in the initial position in the vacuum chamber. Multiple clamping components clamp the shuttle carrying the target sheet together. Multiple moving components move the shuttle to align its collimator. The target sheet is in the irradiation position in the accelerator beam path and is irradiated. The helium cooling component 200 and the water cooling component 300 are used to perform helium cooling cycle and water cooling cycle on the target sheet, respectively.

[0056] It should be noted that the working method of the water-helium dual-cooled accelerator solid target device of this invention application may or may not employ any of the water-helium dual-cooled accelerator solid target devices described in the first aspect. When the water-helium dual-cooled accelerator solid target device described in the first aspect is employed, it also includes all the technical problems, technical solutions and technical effects described in any of the water-helium dual-cooled accelerator solid target devices in the first aspect, which will not be repeated here.

[0057] In some embodiments, the above technical content may be formed or used as step S100.

[0058] In some embodiments, multiple clamping components jointly clamp a shuttle carrying a target sheet, and multiple moving components move the shuttle to engage its collimator. The target sheet is positioned at an irradiation location within the accelerator beam path. A helium-cooling component 200 and a water-cooling component 300 are respectively used to perform helium-cooling and water-cooling cycles on the target sheet. All technical problems, technical solutions, and technical effects described in the first aspect, including multiple clamping components jointly clamping a shuttle carrying a target sheet, and multiple moving components moving the shuttle to engage its collimator, with the target sheet positioned at an irradiation location within the accelerator beam path, are addressed. All the technical problems, technical solutions, and technical effects of the helium cooling component 200 and the water cooling component 300 used for helium cooling cycle and water cooling cycle of the target plate are the same. Specifically, please refer to the description in the first aspect, in which multiple clamping components jointly clamp the shuttle carrying the target plate, multiple moving components move the shuttle to make its collimator cooperate, and the target plate is located in the irradiation position in the accelerator beam path. All the technical problems, technical solutions, and technical effects of the helium cooling component 200 and the water cooling component 300 used for helium cooling cycle and water cooling cycle of the target plate are not repeated in this application.

[0059] In some embodiments, the helium cooling assembly 200 and the water cooling assembly 300 are respectively used for helium cooling and water cooling cycles on the target plate, including: the gas pipe of the helium cooling assembly 200 is connected to the circulation pipeline on the target plate for helium cooling cycle; the water pipe of the water cooling assembly 300 is connected to the circulation water pipe on the target plate for water cooling cycle. Specifically, it may include: For example, after the shuttle moves to the irradiation position in the accelerator beam path, the circulation pipeline is set on the target plate. The first cylinder on the first support frame drives the air pipe to move (e.g., the air pipe moves up and down). The air pipe connector is connected to the circulation pipeline, thus realizing the connection between the circulation pipeline and the air pipe. Multiple nozzles are set on the target plate, and the circulation pipeline is connected to the nozzles. Helium is supplied by a helium source, sent into the air pipe by an air pump, and then enters the circulation pipeline. Helium is sprayed out from multiple nozzles, flows along the surface of the target plate to absorb heat, and is collected through the return pipeline. The return pipeline is connected to the helium assembly. The collected helium can be returned to the helium assembly after cooling. The helium can be recycled again, thus forming a helium cooling cycle.

[0060] For example, a heat-conducting plate is provided on the back of the target plate, and a circulating water pipe is embedded or welded to the heat-conducting plate. The circulating water pipe can be arranged in a serpentine or parallel pattern. The second cylinder on the second support frame drives the water pipe to move (e.g., the water pipe moves up and down). The water pipe joint is connected to the circulating water pipe, thus realizing the connection between the water pipe and the circulating water pipe. The cooling water is supplied by an external water source, and after being pumped into the water pipe, it enters the circulating water pipe. After absorbing the heat of the target plate, the cooling water can be cooled again and then flow back to the water-cooling assembly to achieve water-cooling of the target plate. The cooling water can also be recycled, thus forming a water-cooling cycle.

[0061] Optionally, after the target sheet is irradiated, the helium cooling assembly 200 and the water cooling assembly 300 stop performing helium cooling and water cooling cycles on the target sheet, respectively. Multiple moving components drive the shuttle back to its initial position in the vacuum chamber, and multiple clamping components release the shuttle carrying the target sheet together.

[0062] In some embodiments, the above technical content may be formed or used as step S200.

[0063] In some embodiments, after the target irradiation is completed, the helium cooling assembly 200 and the water cooling assembly 300 respectively stop performing helium cooling and water cooling cycles on the target, and multiple moving components drive the shuttle back to its initial position in the vacuum chamber. The grippers of multiple clamping components jointly release the shuttle carrying the target. All the technical problems, technical solutions, and technical effects described in the first aspect are the same as those described in the first aspect: after the target irradiation is completed, the helium cooling assembly 200 and the water cooling assembly 300 respectively stop performing helium cooling and water cooling cycles on the target, and multiple moving components drive the shuttle back to its initial position in the vacuum chamber. All the technical problems, technical solutions, and technical effects of the shuttle carrying the target sheet being released by the grippers of multiple clamping components at its initial position in the vacuum chamber are the same. Specifically, please refer to the description in the first aspect that after the target sheet is irradiated, the helium cooling component 200 and the water cooling component 300 stop performing helium cooling and water cooling cycles on the target sheet, respectively. Multiple moving components drive the shuttle back to its initial position in the vacuum chamber, and all the technical problems, technical solutions, and technical effects of the shuttle carrying the target sheet being released by the grippers of multiple clamping components are not repeated in this application.

[0064] In some embodiments, stopping the helium cooling assembly 200 and the water cooling assembly 300 for helium cooling and water cooling cycles on the target plate, respectively, includes: the helium cooling assembly 200 stopping helium cooling cycles on the target plate, the gas pipe of the helium cooling assembly 200 disconnecting from the circulation pipe connected to the target plate; and the water cooling assembly 300 stopping water cooling cycles on the target plate, the water pipe of the water cooling assembly 300 disconnecting from the circulation water pipe connected to the target plate. Specifically, this may include: For example, after the target sheet is irradiated, the helium cooling assembly 200 stops the helium cooling cycle for the target sheet, the first cylinder on the first support frame drives the air pipe to move (e.g., the air pipe moves up and down), and the air pipe connector is disconnected from the connection circulation pipeline.

[0065] For example, the water cooling assembly 300 stops circulating water to the target plate, the second cylinder on the second support frame drives the water pipe to move (e.g., the water pipe moves up and down), and the water pipe connector disengages from the circulating water pipe.

[0066] In the working method of the water-helium dual-cooled accelerator solid target device of this invention, multiple clamping and moving components cooperate to move the shuttle to the irradiation position aligned with the collimator, ensuring that the target sheet is accurately in the beam path, reducing scattering and improving the irradiation effect. The automated clamping, moving and releasing of the target sheet, combined with a blower or gravity transport, eliminates the radiation risk of manual operation. After irradiation, the target sheet automatically returns to the initial position and is transported to the hot chamber, improving safety. The innovative water-helium dual-cooling technology combined with the automated operation mechanism improves the heat dissipation performance and safety of the solid target device, meeting the needs of nuclear physics experiments, materials science research and medical isotope production for high heat load and high radiation environment.
