Description

Technical Field

[0001] The invention relates to the technical field of accelerators, in particular to a novel rotating tomographic beam subsystem testing device. Background Art

[0002] The rotating tomographic beam subsystem belongs to the field of accelerators. It works under high-energy microwaves and consists of multiple subsystems such as microwave system, electrical system and water cooling system. Before the whole machine is installed and put into final test and use, the performance of each subsystem needs to be tested, and the stability and reliability of the synchronous operation of each subsystem needs to be analyzed and evaluated. This process requires the use of various scientific instruments, and shielding protection is required during testing, so it can only be carried out in the laboratory.

[0003] The test device of the rotating tomography beam system must meet two requirements. The first requirement is to miniaturize the system and build it on the test platform. The second requirement is to provide convenient experimental conditions for the test, such as the placement of the water tank of the test device and the alignment of the beam line.

[0004] At present, the existing multi-stage rotating fault beam subsystems on the market are mostly surrounded by the slip ring drum to form a two-dimensional disk layout in order to meet market and application needs. However, when this disk-like structure is tested in the laboratory, it is placed horizontally and occupies too much area, and cannot be used in the limited space of most shielded laboratories. At the same time, during experimental testing, high-precision positioning water tank systems and probes and other instruments are required to test data such as PDD curves. The disk-shaped horizontally placed rotating fault beam system cannot adapt to the shape and position requirements of the water tank system, and therefore cannot test the data. Therefore, it is necessary to design a new type of special testing device. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a new type of rotating tomography beam subsystem test device to solve the problem that the rotating tomography beam subsystem is relatively large and the space in most laboratories is limited, making it impossible to conduct experiments in its original form. Therefore, in order to meet the test conditions, it is very important to design a test device that occupies a smaller area.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel rotating fault beam subsystem test device, comprising a main body support, a second fixing plate is arranged on the top of the main body support, an accelerating tube and a shielding body thereof are fixedly connected to the top of the second fixing plate through a special adapter part, a first fixing plate is fixedly connected to one side of the main body support through a first connecting member and a second connecting member, the first connecting member and the second connecting member are both right-angle connecting members, and a plurality of groups of bolts are threadedly connected between the first connecting member, the second connecting member and the main body support, a four-terminal circulator is movably arranged on the first fixing plate, a magnetron is arranged at the bottom of the four-terminal circulator, a spatial twist waveguide is fixedly connected between the accelerating tube and its shielding body and the four-terminal circulator, a carrying trolley is arranged below the main body support, and a water tank test system is arranged on the carrying trolley.

The accelerating tube is located in the center of the main support. At the same time, the following four-end circulator, magnetron and other components are carried on the side wall of the main frame through the spatial twist waveguide, thereby reducing the overall footprint of the equipment. The main support forms a square frame, and the accelerating tube harness is located at the lower end of the center of the main support.

[0015] By adopting the above technical solution, the set limit plate can fix the protective box on the first fixed plate for use, and then through the mutual cooperation between the protective box and the first cooling fan and the second cooling fan, the magnetron can be well protected and dissipated. When the protective box is composed of multiple groups of single-group panels, it is beneficial to adjust the structure of the protective box according to actual usage, and the lock can help the protective box to be flexibly opened and closed.

[0016] The present invention is further configured such that the test water tank and the probe of the water tank test system are located directly below the accelerating tube and the shielding body thereof.

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure.

[0033] A new type of rotating tomography beam subsystem test device, such as Figure 1-7 As shown, it includes a main frame 2, a second fixing plate 16 is arranged on the top of the main frame 2, and an accelerating tube and its shielding body 1 are fixedly connected to the top of the second fixing plate 16 through a special adapter part, a first fixing plate 15 is fixedly connected to one side of the main frame 2 through a first connecting piece 18 and a second connecting piece 22, the first connecting piece 18 and the second connecting piece 22 are both right-angle connecting pieces, and multiple groups of bolts are threadedly connected between the first connecting piece 18 and the second connecting piece 22 and the main frame 2, a four-terminal circulator 4 is movably arranged on the first fixing plate 15, a magnetron 5 is arranged at the bottom of the four-terminal circulator 4, a space twist waveguide 3 is fixedly connected between the accelerating tube and its shielding body 1 and the four-terminal circulator 4, a carrying trolley 9 is arranged below the main frame 2, and a water tank testing system 8 is arranged on the carrying trolley 9.

[0034] When in use, the accelerating tube and its shielding body 1 are vertically fixed on the main support 2 through the cooperation of the second fixing plate 16 and the special adapter parts, so as to achieve miniaturization and lightweight. The accelerating tube is located in the center of the main support 2. At the same time, the following four-end circulator 4, magnetron 5 and other components are carried on the side wall of the main frame through the spatial twist waveguide 3, thereby reducing the overall footprint of the equipment. Through the cooperation between the first connecting member 18 and the second connecting member 22, the first fixing plate 15 can be firmly fixed on the main support 2 for use, and the main support 2 forms a square frame. The accelerating tube harness is located at the lower end of the center of the main support 2. With this structure, the space occupied by the system can be further reduced. At the same time, the device is equipped with a special trolley to carry the water tank, so as to facilitate the transportation and fine-tuning of the water tank, and the test equipment can be replaced at any time.

[0035] Furthermore, the main support 2 is constructed of 6061 aluminum profiles, and the overall structure is stabilized by miter beams. The lower end is provided with anchors 7 to adjust the horizontality of the frame to ensure that the accelerating tube and its shielding body 1 are vertically fixed. The structural strength of the main support 2 can be made more stable by the reinforcing block 17. When the main support 2 and the reinforcing block 17 are fixed by fixing bolts, the reinforcing block 17 can be flexibly installed and removed. The accelerating tube and its shielding body 1, the space twist waveguide 3, the four-terminal circulator 4 and the magnetron 5 are all rigidly connected, so that the beam system can operate in a high-energy and high-vacuum environment. The first adjustment structure 6, the second adjustment structure 13 and the third adjustment structure 14 can provide fixed support for the magnetron 5, the four-terminal circulator 4 and the space twist waveguide 3, and can also provide them with multiple degrees of freedom adjustment functions, so that the flanges can be tightly connected, thereby ensuring vacuum stability.

[0036] The limit plate 19 provided in this embodiment can fix the protection box 11 on the first fixing plate 15 for use, and then the protection box 11 and the first cooling fan 12 and the second cooling fan 21 cooperate with each other, so as to achieve good protection and heat dissipation effects on the magnetron 5. When the protection box 11 is composed of multiple groups of single-group panels, it is beneficial to adjust the structure of the protection box 11 according to actual usage conditions.

When the accelerating tube and its shielding body 1 are made of metals such as copper, tungsten and lead, deformation of the tube body can be avoided under high vacuum conditions, thereby affecting the safety of the experimental device and the accuracy of the experimental structure. The installation can be achieved with the help of a bridge crane through the lifting ring 10.

[0037] Specific embodiments, such as Figure 4 As shown: The new rotating tomography beam subsystem test device is located in the circled position in the figure, occupying only about 1.2㎡ of the laboratory floor area, while the original two-dimensional disk-shaped horizontal test device occupies an area of ​​about 5.3㎡. The new rotating tomography beam subsystem test device occupies only 22% of the original device, which greatly improves the utilization rate of ground space and is more suitable for use in a variety of venues with limited space.

[0038] To build the test device, we first used a special trolley to transport the various parts of the rotating tomography beam subsystem into the laboratory through the maze. Since the maze is narrow and only 960mm wide, the spatial posture of large parts needs to be adjusted in real time according to the changes in the maze terrain during transportation. Then the various parts that have been transported into the laboratory are assembled into corresponding components, and each component is built on the main frame in turn by a crane. Finally, the vacuum system, water cooling system and electrical system are connected to check whether each system is working properly. Finally, various test instruments such as water tank detectors are placed under the beam with a trolley, experimental data are collected, and optimization and adjustment are analyzed, and finally the test work of the entire rotating tomography beam subsystem is completed.

[0039] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
