[0002] Particle accelerator beam transport lines contain various equipment such as magnets, high-frequency cavities, vacuum pumps, and beam diagnostic equipment. The beam channel not only provides a high-vacuum environment for particle propagation but is also frequently used as a signal reference ground for beam diagnostic systems and scientific experimental signal detection systems. The measurement signals from these systems are characterized by wide bandwidth, weak amplitude, high precision requirements, and extreme susceptibility to electromagnetic noise interference.

[0003] However, magnets, high-frequency equipment, and other sources of strong electromagnetic emission can transmit electromagnetic noise to the beam channel through field coupling, conduction coupling, and other means via the support components that support these devices. This severely contaminates the integrity of the signal reference ground, ultimately leading to distortion in weak signal measurement and inaccurate equipment control.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0044] The present invention will now be described in detail with reference to the accompanying drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments. In the description of the present invention, unless otherwise stated, "at least one" includes one or more. "Multiple" refers to two or more. For example, at least one of A, B, and C includes: A existing alone, B existing alone, A and B existing simultaneously, A and C existing simultaneously, B and C existing simultaneously, and A, B, and C existing simultaneously. In the present invention, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0045] The present invention will now be described in detail with reference to specific embodiments.

[0046] Particle accelerators typically utilize a series of metal supports (hereinafter referred to as "supports") to support and position the magnets, high-frequency devices, vacuum systems, beam diagnostic equipment, and control components distributed along the beam transport line. The vacuum chamber, the space where particle acceleration occurs, is usually made of stainless steel. Besides providing a vacuum environment, it also serves as a reference ground for beam diagnostic systems and some scientific experimental signal detection systems. The measurement signals from these systems are characterized by wide bandwidth, weak amplitude, high precision requirements, and susceptibility to electromagnetic noise. Because magnets and high-frequency devices have strong electromagnetic emission levels, they affect the electromagnetic noise level in the beam channel through field coupling and conductive coupling, thereby impacting weak signal testing and control. Because the support components in traditional designs connect the beam pipe and equipment directly or indirectly—for example, some nearby equipment share support components or are connected via grounding—these components become the main coupling pathways for electromagnetic noise interference to the beam pipe. Therefore, based on the inherent structure and function of the accelerator, it is necessary to design the distribution scheme and grounding method of the support components to suppress the electromagnetic noise level on the beam pipe and ensure that equipment such as weak signal testing and control uses the beam pipe as a clean reference ground.

[0047] To suppress the electromagnetic noise level in the beam pipe of a particle accelerator and thus ensure the reliability and accuracy of beam detection and equipment control, a support design method for reducing electromagnetic noise in the beam pipe of a particle accelerator is presented.

[0048] In view of this, in some specific embodiments of the present invention, such as Figure 1 As shown, this solution provides a design method for a particle accelerator beam pipe support, including the following steps:

[0049] Step 100: Based on the electromagnetic characteristics of each device on the beam transport line and its structural relationship with the beam pipe, classify them into interference source devices and sensitive devices;

[0050] Step 200: Independently configure support components for the interference source device, the sensitive device, and the beam pipe;

[0051] Step 300: Connect the support or body of the interference source device to the electrostatic protection grounding busbar, and connect the beam pipe to the electrostatic protection grounding busbar through the resistor-capacitor filter on both sides of the front and rear of the beam pipe passing through the interference source device.

[0052] Step 400: Electrically isolate the support of the sensitive device from the beam pipe, connect the support to the electrostatic protection ground, and simultaneously filter and connect the beam pipe to the signal ground near the sensitive device.

[0053] Step 500: Electrically isolate the beam pipe from its own support, and filter and connect the beam pipe to the signal ground at the support.

[0054] It should be noted that the existing support component design, due to the shared support components and chaotic grounding, causes noise from strong electromagnetic interference equipment (interference sources) to be directly coupled to the beam pipe, thereby contaminating the signal reference ground of sensitive equipment.

[0055] Therefore, based on the different electromagnetic roles of the devices, this invention classifies them into two main types: interference source devices and sensitive devices, and accordingly carries out differentiated support and grounding designs. By using independent support components, interference is prevented from being directly conducted through shared metal brackets. By connecting the beam pipes of the interference source area and the sensitive area to different grounding bars (static protection ground or signal ground), the noise current and signal reference ground are separated, ensuring the cleanliness of the signal reference ground at the sensitive device.

[0056] In some possible embodiments of the present invention, the interference source device includes a first type of interference source device and a second type of interference source device;

[0057] Correspondingly, based on the electromagnetic characteristics of each device on the beam transport line and their structural relationship with the beam pipe, they are classified into interference source devices and sensitive devices, specifically including:

[0058] Devices that affect the beam channel through field-path coupling and are not directly electrically connected to the beam channel are defined as Class I interference source devices;

[0059] Devices that are directly electrically connected to the beam channel and affect the electromagnetic noise of the beam channel through conduction are defined as Class II interference source devices;

[0060] Devices that use the beam channel as a signal reference ground are defined as sensitive devices.

[0061] Specifically, this embodiment provides an implementation method for classifying equipment on a beam transport line, clarifying the specific connotations of interference source equipment and sensitive equipment, and providing a precise decision-making basis for subsequent differentiated measures. The classification standard is objective and operable, allowing testers to correctly classify the equipment without ambiguity based on its working principle and physical connection method, thereby triggering appropriate subsequent technical measures.

[0062] Specifically, interference source devices can be further divided into two subtypes based on their different interference coupling mechanisms:

[0063] Category 1 interference source devices refer to devices that affect the beam channel through field-path coupling and are not directly electrically connected to the beam channel. This type corresponds to "Category 1 devices" in the following specific embodiments, and a typical example is a magnet.

[0064] The second type of interference source equipment refers to equipment that is directly electrically connected to the beam channel and affects the electromagnetic noise of the beam channel through conduction. This type corresponds to the "second type of equipment" in the following specific embodiments, and typically includes high-frequency equipment, vacuum equipment, etc.

[0065] The term "sensitive equipment" refers to measurement and control equipment that uses the beam channel as a signal reference ground and is highly sensitive to electromagnetic interference. This type corresponds to the "three types of equipment" in the following specific embodiments, and typically includes beam diagnostic equipment, etc.

[0066] In some possible embodiments of the present invention, connecting the beam pipe filter to signal ground specifically includes:

[0067] The beam channel is connected to the signal ground bus via an RC filter.

[0068] Specifically, this embodiment provides an implementation method for connecting the beam pipe filter to the signal ground. The RC filter provides a low-impedance discharge path for high-frequency noise while maintaining DC isolation, and is an effective device for suppressing high-frequency noise on the pipe.

[0069] In some possible embodiments of the present invention, the first type of interference source device includes a magnet, the second type of interference source device includes a high-frequency device and a vacuum device, and the sensitive device includes a beam diagnostic device.

[0070] Specifically, this embodiment provides an implementation method for interference source devices and sensitive devices. Magnets, high-frequency devices, vacuum devices, and beam diagnostic devices are the most important and typical devices in particle accelerators, and these devices are the main contributors and victims of EMI problems.

[0071] In some possible embodiments of the present invention, for the vacuum device, after connecting the support or body of the interference source device to the electrostatic protection ground busbar, and connecting the beam pipe to the electrostatic protection ground busbar through RC filters on both sides of the beam pipe passing through the interference source device, the method further includes:

[0072] An EMI absorption magnetic ring is fitted onto the grounding wire of the support component of the vacuum equipment and onto the external cable of the vacuum equipment.

[0073] Specifically, this embodiment provides an implementation method for grounding and filtering vacuum equipment. By absorbing high-frequency common-mode noise on the cable through a magnetic ring, it provides additional and targeted EMI suppression, further reducing the noise level and solving the problem that the external cable of the vacuum equipment may become an antenna, radiating or receiving secondary interference noise.

[0074] In some possible embodiments of the present invention, the electrical isolation of the support member of the sensitive device from the beam channel, or the electrical isolation of the beam channel from its own support member, includes:

[0075] The electrical isolation is achieved by providing an insulating element, which includes at least one of an insulating gasket, an insulating bushing, or an insulating mounting clip.

[0076] Specifically, this embodiment provides an implementation method for electrical isolation, which achieves electrical isolation by setting insulating components (such as gaskets, bushings, and mounting clips). The insulating components physically block the current path, which is the simplest and most direct method to achieve electrical isolation and ensures the reliability of the isolation.

[0077] The design method for particle accelerator beam pipe support provided by this invention reduces the electromagnetic noise impact of strong electromagnetic emission equipment such as magnets and high-frequency devices on the beam pipe by optimizing the distribution of the support and its grounding scheme, thereby enabling reliable and high-quality operation of weak signal measurement and control systems such as beam diagnostics.

[0078] The preferred embodiments of the present invention will be described in detail below using the classification system of interference source devices and sensitive devices as an example. In this embodiment, the interference source devices are specifically categorized into Class I devices and Class II devices, and the sensitive devices are specifically categorized into Class III devices.

[0079] Specifically, the design method for the particle accelerator beam pipe support provided in this embodiment includes the following steps:

[0080] Step 1: Equipment Classification

[0081] In this step, beam transport line equipment is classified according to electromagnetic emission, sensitivity, and inherent structure, such as... Figure 2As shown, the equipment is divided into three categories. Magnet 14 is classified as Category I equipment; high-frequency equipment 13 and vacuum equipment 15 (such as vacuum pumps) are classified as Category II equipment; and beam diagnostic equipment 12 is classified as Category III equipment. The specific classification results include:

[0082] One type of equipment affects the electromagnetic noise of the beam channel through field-path coupling. These devices generally do not have a direct electrical connection to the beam channel; typical examples include magnets. Because the beam channel passes through a magnet, the magnet generates electromagnetic noise in the beam channel through field-path coupling. This phenomenon is particularly pronounced in synchrotrons. Magnets are one of the main causes of electromagnetic noise in the beam channel.

[0083] Category II equipment: Transmitter equipment directly connected to the beam channel, which affects the electromagnetic noise of the beam channel through conduction. Typical equipment includes high-frequency equipment and vacuum pumps. Due to their inherent structure, these devices cannot be isolated from the beam channel, and the electromagnetic noise they generate has a certain transmission distance and range of influence in the beam channel.

[0084] Category III equipment: Sensitive equipment that uses the beam channel as a signal reference ground. Typical equipment includes beam diagnostic equipment, scientific research experimental signal detection equipment, and signal control equipment.

[0085] Step 2: Design of support component allocation, grounding, and filtering schemes:

[0086] like Figure 3 As shown, each magnet 14 in a type of equipment is equipped with an independent support 41. A grounding wire is installed between the magnet core and the support, and the magnet core is connected to the electrostatic protection ground bus 31 through the grounding wire 34. The beam pipe 11 is connected to the same electrostatic protection ground bus 31 on both sides before and after the magnet 14 it passes through, respectively, through RC filters 21, in order to reduce the conducted noise of the magnet coupling to the beam pipe through the field path.

[0087] An independent support component 41 is configured for the high-frequency equipment 13 in the Class II equipment, and the support component 41 is connected to the electrostatic protection ground bus 31 through a grounding wire. The beam duct 11 is connected to the electrostatic protection ground bus 31 on both sides before and after the high-frequency equipment it passes through, respectively, through RC filters 21, in order to mitigate the conducted noise of the high-frequency equipment on the beam duct.

[0088] A separate support is provided for the vacuum equipment 15 in Class II equipment, and this support is connected to the electrostatic discharge protection grounding busbar 31 via a grounding wire 34. An EMI absorption magnetic ring 22 is fitted onto this grounding wire 34. The external cables of the vacuum equipment 15 are... Figure 3 An EMI-absorbing magnetic ring 22 is also added to the interconnecting cable 16 of the vacuum equipment used in the process to reduce the electromagnetic noise contribution of external cables to the beam pipe.

[0089] Independent support components 41 are configured for sensitive equipment such as the beam diagnostic equipment 12 in the three types of equipment. These support components 41 are secured to the beam pipe 11 using insulating components 42 to achieve electrical isolation. When these support components are secured to the ground, they should be insulated from the reinforced concrete reinforcement. These support components are connected to the electrostatic discharge (ESD) grounding busbar 31. The beam pipe 11 is connected to the signal grounding busbar 32 at the location of sensitive equipment such as the beam diagnostic equipment 12 via an RC filter 21.

[0090] The beam channel 11 also has its own independent support member 41, which is fastened and isolated from the beam channel 11 by an insulating member 42, so that the beam channel 11 and its support member 41 are electrically insulated. The beam channel 11 is connected to the signal ground bus 32 at the support member 41 through an RC filter 21.

[0091] Step 3: Grounding system setup:

[0092] In this step, the electrostatic discharge (ESD) grounding busbar 31 is directly fixed to a nearby support and connected to a dedicated grounding point derived from the grounding grid, while also reliably connecting to the PE busbar of the AC power distribution in the computer room. The signal grounding busbar 32 is insulated from the support via an insulating mounting clip 33 and connected to another dedicated signal grounding point derived from the grounding grid.

[0093] Through the above implementation methods, strong interference sources are effectively isolated and a clean reference ground is provided for sensitive signals. Actual measurements show that the background electromagnetic noise on the beam pipe can be reduced by more than 20dB.

[0094] In some specific embodiments of the present invention, this solution provides a particle accelerator beam pipe support system for reducing electromagnetic interference in particle accelerator beam pipes, the system being constructed using the design method described in any of the above embodiments.

[0095] In some specific embodiments of the present invention, such as Figure 3 As shown, this solution provides a particle accelerator beam pipe support system for reducing electromagnetic interference in particle accelerator beam pipes, including:

[0096] Beam tube 11;

[0097] Multiple independent support components 41 are used to support the beam pipe, interference source equipment and sensitive equipment, respectively;

[0098] Insulating element 42 is disposed between the beam pipe and its support, and between the support of the sensitive device and the beam pipe;

[0099] The grounding system includes an electrostatic discharge protection ground busbar 31 and a signal ground busbar 32;

[0100] Filtering devices such as Figure 3The RC filter 21 is used to connect the beam pipe to the electrostatic protection ground bus in the interference source equipment area and to the signal ground bus in the sensitive equipment area.

[0101] Possibly, the interference source device includes a first type of interference source device and a second type of interference source device;

[0103] The second type of interference source device is a device that is directly electrically connected to the beam pipe and affects its electromagnetic noise through conduction;

[0104] The sensitive device is one that uses the beam pipe as a signal reference ground.

[0105] Specifically, this embodiment provides an implementation method for a beam conduit, an interference source device, and a sensitive device.

[0106] Possibly, the first type of interference source device is a magnet, the magnet's support is independently set, and the magnet's core is connected to the electrostatic protection ground busbar through a grounding wire.

[0109] Specifically, this embodiment provides an implementation method for setting up a support component for high-frequency equipment and vacuum equipment.

[0110] Possibly, an EMI absorption magnetic ring is fitted onto the grounding wire of the support component of the vacuum device.

[0111] Specifically, this embodiment provides another implementation method for setting up a vacuum equipment support component.

[0112] The design method and system for a particle accelerator beamline support provided in this invention address the issue of direct interference caused by shared support components by setting up separate support components for accelerator beamline equipment according to equipment type. Through filtering and isolation measures, the beamline is separated from the support components and grounding system, mitigating the electromagnetic noise contribution of the beamline equipment to the beamline through the support components. This support component scheme for reducing electromagnetic noise in accelerator beamlines, based on the inherent structure of the accelerator beamline, has good engineering applicability.
