Description

Technical Field

[0001] This utility model relates to the field of cyclotron beam diagnostics technology, specifically to a multi-page Faraday cylinder device. Background Technology

[0002] As a key beam diagnostic component of cyclotrons, the Faraday tube's core function is to measure the beam intensity extracted from the ion source, making it a fundamental device for beam parameter detection.

[0003] However, existing Faraday lamps have significant technical limitations. Their measurement function is limited, only capable of detecting beam intensity, and unable to acquire key parameters such as beam position distribution and energy characteristics. Furthermore, their operating environment is restricted, requiring operation in a vacuum, which increases the environmental cost and operational complexity of the equipment. With the expansion of proton beam applications, higher demands are placed on the multi-parameter measurement capabilities and environmental adaptability of beam diagnostic equipment, and existing technologies are no longer sufficient to meet practical needs.

[0004] Therefore, we propose a multi-page Faraday cylinder device. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a multi-page Faraday cylinder device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a multi-page Faraday cylinder device, including a frame assembly, a measuring assembly, a motion driving assembly, and a signal lead-out terminal. The frame assembly is formed by a receiving cavity enclosed by a multi-page bottom plate, a multi-page rear panel, a multi-page side plate, a multi-page top plate, and a multi-page front panel. The measuring assembly is disposed in the receiving cavity and is composed of measuring plates and insulating plates alternately stacked. The motion driving assembly includes a connecting frame, a rodless cylinder, and a base. One end of the connecting frame is fixedly connected to the frame assembly, and the other end is fixedly connected to the rodless cylinder. The rodless cylinder is fixedly installed on the base. The signal lead-out terminal is fixedly installed on the multi-page side plate.

[0007] By adopting the above technical solution, a frame composed of a multi-page base plate, a multi-page rear panel, a multi-page side panel, a multi-page top plate, and a multi-page front panel is constructed. The measuring plate and the insulating plate are alternately stacked to form an assembly that is encased within the frame and fixed with screws. The moving parts, consisting of a connecting frame, a rodless cylinder, and a base, enable the multi-page Faraday tube to move. That is, the multi-page Faraday tube enters the beamline working range during measurement and leaves the beamline working range when not measuring. Through the integrated design of the four major components, a measuring device with signal acquisition, structural support, position adjustment, and signal output capabilities is constructed, laying the foundation for multi-parameter detection.

[0008] Specifically, both the measuring plate and the insulating plate have 22 layers, and they are alternately stacked along the height direction of the frame assembly to form the measuring component.

[0009] By adopting the above technical solution, the 22-layer alternating stacked structure design significantly improves the spatial resolution of the measurement, enabling precise capture of the spatial distribution differences of the proton beam and its surrounding halo, providing hardware support for subsequent acquisition of position and energy information through electronic processing.

[0010] Specifically, the multi-page base plate, multi-page rear panel, multi-page side panel, multi-page top plate, and multi-page front panel of the frame assembly are fixedly connected by screws, and the measuring component is wrapped and limited.

[0011] By adopting the above technical solutions, the screw connection ensures the stability of the frame structure and adapts to the mechanical requirements of the beam measurement environment. The wrapping and limiting design of the measurement components prevents them from shifting under device movement or beam impact, thus ensuring measurement accuracy.

[0012] Specifically, the connecting frame is fixed to the rodless cylinder with screws, and the rodless cylinder is fixed to the base with screws, forming a motion mechanism that can drive the frame assembly into and out of the beamline working range.

[0013] By adopting the above technical solution and utilizing the linear drive characteristics of the rodless cylinder, the device can enter during measurement and exit when not measuring, thus avoiding interference with the normal transmission of the beamline and improving the flexibility of equipment use.

[0014] Specifically, the measuring plate and the insulating plate are alternately stacked and fixed by the inner wall of the frame assembly, and the signal output terminal of the measuring plate is electrically connected to the signal lead-out terminal.

[0015] By adopting the above technical solution, the structural stability of the measurement component is further enhanced by double limiting and fixing, and the electrical connection between the measurement board and the signal lead-out terminal realizes lossless transmission of the acquired signal, ensuring the accuracy of subsequent electronic processing.

[0016] The beneficial effects of this utility model are: (1) The multi-page Faraday tube device described in this utility model expands the measurement dimensions: it breaks through the limitation of existing technology that can only measure beam intensity, and can obtain the position and energy information of the proton beam and its surrounding halo online. It does not rely on a vacuum environment and can work stably in the atmosphere, reducing the cost of equipment use.

[0017] (2) The multi-page Faraday tube device described in this utility model has strong operational flexibility. It can flexibly enter and exit the working range of the beam line through the motion drive component without affecting the normal transmission of the beam. The multi-layered alternating measurement components and the stable structural design ensure the accuracy and stability of signal acquisition. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 As shown, the multi-page Faraday cylinder device of this utility model includes a frame assembly, a measuring assembly, a motion driving assembly, and a signal output terminal 11. The frame assembly is formed by a multi-page bottom plate 1, a multi-page rear panel 2, a multi-page side panel 3, a multi-page top plate 4, and a multi-page front panel 7 enclosing a receiving cavity. The measuring assembly is disposed in the receiving cavity and is composed of a measuring plate 5 and an insulating plate 6 alternately stacked. The motion driving assembly includes a connecting frame 8, a rodless cylinder 9, and a base 10. One end of the connecting frame 8 is fixedly connected to the frame assembly, and the other end is fixedly connected to the rodless cylinder 9. The rodless cylinder 9 is fixedly installed on the base 10, and the signal output terminal 11 is fixedly installed on the multi-page side panel 3.

[0022] During use, the frame components form a closed protective space, isolating the measurement components from radiation and low temperature (such as liquid nitrogen cooling zone) in the beamline environment. The alternating structure of the measurement board 5 and the insulating board 6 enables layered measurement of the beam. The shielding design of the signal lead-out terminal 11 reduces electromagnetic leakage. The overall structure is modular, adaptable to the installation requirements of different beamline equipment, and highly versatile.

[0023] For example, such as Figure 1 As shown, both the measuring plate 5 and the insulating plate 6 have 22 layers, and they are alternately stacked along the height direction of the frame assembly to form the measuring assembly.

[0024] In use, the 22-layer measurement points enable high-resolution measurement of the beam spatial distribution, and can simultaneously acquire beam density data from 22 cross sections to meet the requirements of high-precision diagnosis. The multi-layer superimposed structure improves beam interception efficiency.

[0025] For example, such as Figure 1 As shown, the multi-page base plate 1, multi-page rear panel 2, multi-page side panel 3, multi-page top plate 4, and multi-page front panel 7 of the frame assembly are fixedly connected by screws, and the measuring component is wrapped and limited.

[0026] During use, the screw connection method ensures the rigidity of the frame structure, guaranteeing the accuracy of the measurement position under beam impact and equipment vibration. The detachable panel design facilitates the maintenance and replacement of the measurement components, improving maintenance efficiency. The fully enclosed structure avoids the exposure of the measurement board 5, reducing the impact of secondary electron emission on the measurement results.

[0027] For example, such as Figure 1 As shown, the connecting frame 8 is fixed to the rodless cylinder 9 by screws, and the rodless cylinder 9 is fixed to the base 10 by screws, forming a motion mechanism that can drive the frame assembly into and out of the beamline working range.

[0028] When in use, the magnetic coupling design of the rodless cylinder 9 saves axial space, adapts to the compact installation environment of the beamline equipment, has a fast motion response speed, and enables rapid switching between measurement and non-measurement states. The rigid connection fixed by screws ensures stable transmission of driving force, and the rodless cylinder 9 can withstand the weight of the frame assembly for a long time.

[0029] For example, such as Figure 1 As shown, the measuring plate 5 and the insulating plate 6 are alternately stacked and fixed by the inner wall of the frame assembly, and the signal output terminal of the measuring plate 5 is electrically connected to the signal lead-out terminal 11.

[0030] During use, the inner wall limit does not require additional fasteners, simplifying the structure while avoiding interference from foreign objects in the beam path and improving beam throughput. The welded electrical connection reduces contact impedance and signal transmission loss, ensuring accurate acquisition of weak beam signals. Each measurement board has independent wiring, allowing for individual troubleshooting in case of faults and improving equipment fault tolerance.

[0031] In use, during measurement, the rodless cylinder 9 drives the slider to move the connecting frame 8 and the frame assembly horizontally, bringing the measuring component into the beamline's working range. The proton beam and its corona bombard the measuring plate 5, and the resulting charge signal is transmitted to the signal output terminal 11 via a shielded wire. This signal is then processed by external electronic equipment to obtain the target's position and energy information. When not in measurement mode, the rodless cylinder 9 reverses its direction to remove the device from the beamline, thus avoiding interference with beam transmission.

[0032] It should be noted that this utility model is a multi-page Faraday cylinder device. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
