[0036] The present application embodiment provides an isotope electromagnetic separation system 100, see Figures 1 to 3 An isotope electromagnetic separation system 100 includes an ion source 30, a vacuum chamber 40, a receiving device 20 and a receiver installation device 10. The ion source 30 is used to ionize the raw material to be separated to form a plasma. The vacuum chamber 40, wherein a magnet system is arranged in the vacuum chamber 40, is used to generate a magnetic field that deflects the plasma. The receiving device 20 includes a main body 201, a first fixing member 202 and a receiver 203, at least two first fixing members 202 are arranged on the main body 201, and each first fixing member 202 is arranged in sequence along a first direction away from the ion source 30, and the receiver 203 can be connected to the first fixing member 202. The receiver installation device 10 includes a moving component 1 and a second fixing member 2, wherein the second fixing member 2 is arranged on the moving component 1, and the receiver 203 can be pre-installed on the receiver installation device 10 through the second fixing member 2. The moving assembly 1 can at least drive the second fixing member 2 to move along the first direction and the second direction, so that the receiver 203 is selectively installed on at least one first fixing member 202 for receiving separated plasmas of different deflection diameters, wherein the first direction intersects the second direction.

[0037] The ion source 30 is a device that can make the raw materials to be separated (usually atoms or molecules) lose or gain electrons to form charged particles (ions). It is the starting point of the element separation process, and it ionizes the raw materials by providing sufficient energy to generate plasma, creating conditions for subsequent separation using a magnetic field.

[0038] The vacuum chamber 40 is a sealed space, and the internal gas pressure is reduced to a level far below the atmospheric pressure. In the isotope electromagnetic separation system 100, the vacuum environment is very important. On the one hand, it can reduce the interference of gas molecules on the movement of plasma, making the deflection of plasma in the magnetic field more accurate and stable; on the other hand, it prevents the plasma from reacting unnecessarily with impurities in the air, ensuring the purity and accuracy of the separation process.

[0039] The magnet system is a device installed in the vacuum chamber 40, and its function is to generate a magnetic field. In this isotope electromagnetic separation system 100, the magnetic field is used to deflect the plasma. According to the principle that charged particles are subjected to the Lorentz force in the magnetic field, plasmas with different mass-to-charge ratios (ratio of mass to charge) will have different deflection radii under the same magnetic field strength, thereby achieving the separation of elements. For example, an electromagnet is a common magnet system, and the magnetic field strength can be controlled by adjusting the current.

[0040] The receiving device 20 is used to collect different plasmas separated by magnetic field deflection and is composed of a main body 201 , a first fixing member 202 and a receiver 203 .

[0041] The body 201 is the main structure of the receiving device 20, and plays the role of supporting and fixing other components. As the basic structure of the receiving device 20, it plays the role of carrying and fixing other components. The body 201 needs to have sufficient mechanical strength and stability to ensure that its structure will not be deformed or displaced during the entire element separation process, thereby ensuring that the receiver 203 and the first fixing member 202 can accurately perform their respective functions.

[0042] For example, the main body 201 may be made of metal (such as aluminum alloy) and formed into a specific shape, such as a rectangular or cylindrical structure, through precision machining, and its surface may be specially treated to improve wear resistance and corrosion resistance.

[0043] The first fixing member 202 is arranged on the main body 201 along the first direction to provide a mounting position for the receiver 203 and ensure its stability. The main function of the plurality of first fixing members 202 arranged on the main body 201 along the first direction is to provide a reliable connection position for the receiver 203.

[0044] The specific position of the first direction is not limited here. For the convenience of description, the first direction here is the direction shown in the accompanying drawings.

[0045] The design of the first fixing member 202 needs to consider the connection method with the receiver 203, such as using a bayonet type, a threaded type or a magnetic type connection structure, to ensure that when receiving plasma, the receiver 203 can be firmly fixed on the first fixing member 202 and will not loosen or fall off due to the impact of plasma or other external forces.

[0046] The receiver 203 is a component that directly contacts with the plasma and collects it. Its material and structure need to be able to adapt to the characteristics of the plasma, such as resistance to high temperature and resistance to ion bombardment.

[0047] The shape of the receiver 203 can be cup-shaped, disc-shaped or other shapes suitable for collecting plasma. The connection between the receiver 203 and the first fixing member 202 needs to be convenient for quick installation and removal so that it can be replaced or cleaned in time after collecting full plasma.

[0048] The receiver mounting device 10 mainly includes a moving component 1 and a second fixing component 2 .

[0049] The moving component 1 can move the second fixing component 2 in space, and its function is to transfer the receiver 203 from one position to the corresponding first fixing component 202 of the receiving device 20 .

[0050] The moving component 1 can be driven in a variety of ways, such as a linear motor drive, a screw nut transmission mechanism drive, or a pneumatic or hydraulic drive.

[0051] The second fixing member 2 is used to connect the receiver 203 and ensure the stability of the receiver 203 during the movement. The receiver installation device 10 can realize the transfer and precise positioning of the receiver 203, thereby improving the working efficiency and accuracy of the isotope electromagnetic separation system 100.

[0052] The structural design of the second fixing member 2 should match the connection part of the receiver 203. For example, it may be a metal member with a threaded hole or a bayonet, and the receiver 203 is firmly fixed to the mobile component 1 by threaded connection or snap-fitting. When the receiver 203 moves with the mobile component 1, the second fixing member 2 should be able to withstand the weight of the receiver 203 and possible external forces such as inertial force and vibration, so as to ensure that the receiver 203 will not loosen or fall off. At the same time, the connection and separation operations between the second fixing member 2 and the receiver 203 should be relatively simple, so that after the receiver 203 reaches the designated position of the receiving device 20, it can be smoothly transferred from the second fixing member 2 to the first fixing member 202.

[0053] The specific position of the second direction is not limited here. For the convenience of description, the second direction here is the direction shown in the accompanying drawings.

[0054] The mobile component 1 uses a specific mechanical structure and power source to enable the second fixed component 2 to move in different directions to adjust the position of the receiver 203 in space, thereby accurately transferring it to the corresponding position of the receiving device 20 and connecting it to the first fixed component 202.

[0055] The moving component 1 has the ability to drive the second fixing member 2 to move in the first direction and the second direction, so that the receiver 203 can be accurately moved to the target position in a two-dimensional plane. When the ion source 30 generates plasma and is deflected by the magnetic field in the vacuum chamber 40, isotopes with different deflection diameters will arrive at the first fixing member 202 at different positions of the receiving device 20. The moving component 1 can accurately position the receiver 203 to the corresponding first fixing member 202 according to the deflection of the isotope and the receiving requirements by making the second fixing member 2 drive the receiver 203 to move in the first direction and the second direction, thereby realizing the effective collection of different isotopes of the same element.

[0056] The isotope electromagnetic separation system 100 provided in the present application deflects the plasma through the magnetic field generated by the magnet system, and utilizes the principle that plasmas with different mass-to-charge ratios have different deflection radii in the magnetic field, so that different isotopes of the same element can be accurately separated. The design that multiple first fixings 202 in the receiving device 20 are arranged along the first direction and the receiver 203 can be connected to the first fixings 202 at different positions enables the system to flexibly adjust the position and number of the receivers 203 according to different separation sequences and production requirements. The first fixing 202 is arranged along the first direction, so that each first fixing 202 is at a different distance from the ion source 30, and the moving assembly 1 can move in two directions, driving the receiver 203 to be flexibly transferred to different first fixings 202, so that the plasmas with different deflection diameters obtained by separation are received by the receiver 203 at the corresponding position, thereby improving the receiving range of the receiver 203. The setting of transferring the receiver 203 to the first fixing 202 by the second fixing 2 reduces the installation difficulty, improves the disassembly and assembly efficiency of the receiver 203, and reduces the error caused by simple manual disassembly and assembly.

[0057] In some embodiments, see Figures 1 to 3 The moving assembly 1 includes a first sliding assembly 11 and a second sliding assembly 12, and the second sliding assembly 12 is disposed on the first sliding assembly 11. The second fixing member 2 is disposed on the second sliding assembly 12. The first sliding assembly 11 drives the second sliding assembly 12 to move along the first direction, driving the receiver 203 to align with one of the first fixing members 202 of the receiving device 20 in the first direction to correspond to the deflection diameter of the separated plasma. The second sliding assembly 12 drives the second fixing member 2 to move along the second direction to fix the receiving position of the receiver 203.

[0058] The first sliding assembly 11 is the basic driving part of the moving assembly 1, which provides power and guidance for the movement of the entire receiver 203 in the first direction. The first sliding assembly 11 can make the second sliding assembly 12 mounted thereon slide smoothly along the first direction, thereby driving the receiver 203 to adjust its position in this direction to match the receiving position corresponding to different plasma deflection diameters.

[0059] For example, a travel limit switch and a buffer are provided at both ends of the first sliding component 11. The travel limit switch is used to detect the limit position of the second sliding component 12 in the first direction to prevent it from exceeding the normal working range and causing a collision accident; the buffer plays a role of buffering and deceleration when the second sliding component 12 approaches the end of the stroke, thereby reducing the damage to the equipment caused by the impact. For example, a hydraulic buffer or a rubber buffer pad can effectively absorb the impact energy.

[0060] The second sliding component 12 is installed on the first sliding component 11, and it increases the movement ability in the second direction on the basis of the movement in the first direction provided by the first sliding component 11. Its main function is to drive the second fixing member 2 and the receiver 203 connected thereto to move in the second direction after the position in the first direction is initially determined, so as to achieve the precise docking of the receiver 203 with the first fixing member 202 of the receiving device 20 in a plane perpendicular to the first direction, and ensure that the receiver 203 can be accurately fixed at the receiving position.

[0061] For example, a position sensor, such as a grating ruler or a magnetic ruler, may be installed on the second sliding component 12 to monitor the position information of the receiver 203 in the second direction in real time and feed back the information to the control system. The control system accurately controls the drive motor of the second sliding component 12 according to the data fed back by the sensor to achieve closed-loop control, further improving the positioning accuracy in the second direction, and the accuracy can reach micron level or even higher.

[0062] The mobile component 1 realizes the precise movement of the receiver 203 in two-dimensional space through the first sliding component 11 and the second sliding component 12 of the hierarchical design. First, the first sliding component 11 works, and according to the deflection radius information of the isotope, the second sliding component 12 is driven to move to the corresponding position along the first direction, so that the receiver 203 is on the same axis with a first fixing member 202 corresponding to the plasma deflection diameter in the receiving device 20 in the first direction such as horizontal or vertical. Then, the second sliding component 12 is started, driving the second fixing member 2 and the receiver 203 to move along the second direction toward the aligned first fixing member 202, gradually approaching and finally fixing on the first fixing member 202, thereby completing the positioning and installation of the receiver 203, and preparing to receive the plasma of a specific deflection diameter. This design allows the position adjustment process of the receiver 203 to be carried out in two steps, first coarse adjustment (first direction) and then fine adjustment (second direction), thereby improving the accuracy and reliability of positioning.

[0063] In some embodiments, see Figures 1 to 3 The first sliding assembly 11 includes a first sliding rail 111 and a first slider 112 . The first slider 112 is slidably disposed on the first sliding rail 111 . The first slider 112 is connected to the second sliding assembly 12 .

[0064] The first slide rail 111 is a long strip component with a specific shape and size, usually made of metal (such as aluminum alloy, stainless steel, etc.), and its surface has a very smooth and precisely processed track surface.

[0065] The main function of the first slide rail 111 is to provide a precise, low-friction sliding guide path for the first slider 112, determine the movement trajectory of the first slider 112 in the first direction, thereby limiting and guiding the movement of the second sliding assembly 12 and the receiver 203 connected thereto in this direction.

[0066] The first sliding block 112 is a component that matches the first sliding rail 111 , and is generally made of metal and is finely processed to ensure good matching accuracy and a low friction coefficient with the first sliding rail 111 .

[0067] The first slider 112 can slide freely on the first slide rail 111 and is a key intermediate component connecting the second slide component 12 and the first slide rail 111. It transmits the guiding and supporting functions provided by the first slide rail 111 to the second slide component 12, so that the second slide component 12 can move smoothly and accurately in the first direction determined by the first slide rail 111.

[0068] The first slide rail 111 may adopt a double-track structure, that is, two parallel slide rails are provided, and the first slider 112 is designed to be in a shape compatible with the double-track, such as an H-shaped or U-shaped slider. This double-track structure can greatly enhance the stability of the first slider 112 during the sliding process, reduce the possibility of shaking and offset, and improve the accuracy of the entire moving assembly 1 in the first direction.

[0069] The first slider 112 can be designed as a structure with adjustable preload. By adjusting the preload device (such as bolts, springs, etc.), the contact pressure and friction between the first slider 112 and the first slide rail 111 can be changed, thereby optimizing the motion performance of the first slider 112 to a certain extent.

[0070] The cooperation between the first slide rail 111 and the first slider 112 provides a precise linear motion guide, so that the movement of the second slide assembly 12 and the receiver 203 in the first direction has a high degree of directionality and accuracy. This precise guide can ensure that the receiver 203 accurately corresponds to the position requirements of different plasma deflection diameters in the first direction, reduce the receiving error caused by inaccurate guidance, and improve the collection efficiency and separation accuracy of the isotope electromagnetic separation system 100.

[0071] In some embodiments, the second sliding assembly 12 includes a second sliding rail 121 and a second sliding block 122 . The second sliding block 122 is slidably disposed on the second sliding rail 121 , and the second sliding block 122 is connected to the second fixing member 2 .

[0072] The second slide rail 121 is a component that plays a guiding role in the second sliding assembly 12 , and is usually a long strip structure with a specific shape and precision requirements, and is generally made of metal materials such as aluminum alloy, steel, etc.

[0073] The second slide rail 121 is used to determine the movement trajectory of the second slider 122 in the second direction, providing an accurate linear motion guide path for the second fixing member 2 and the receiver 203 connected thereto, ensuring that they can be accurately positioned in a plane perpendicular to the first direction.

[0074] The second slider 122 is a component that matches the second slide rail 121 and can slide thereon. It is also made of metal. Its shape and size are compatible with the track shape of the second slide rail 121 to ensure good matching accuracy and low friction coefficient.

[0075] The second slider 122 serves as a key element connecting the second fixing member 2 and the second slide rail 121, transmitting the guiding function of the second slide rail 121 to the second fixing member 2, so that the second fixing member 2 can drive the receiver 203 to move smoothly and accurately in the second direction, so as to dock and fix with the first fixing member 202 of the receiving device 20.

[0076] The second slide rail 121 can adopt a segmented structure, and each segment of the slide rail is connected by a high-precision connection device (such as a positioning pin and a bolt). This segmented design facilitates adjustment and replacement of the second slide rail 121 during equipment installation and maintenance, especially when the system needs to be upgraded or part of the slide rail is damaged, it can be handled more flexibly.

[0077] The design of the second slide rail 121 and the second slider 122 enables the receiver 203 to be accurately adjusted in the second direction, thereby achieving accurate docking with the first fixing member 202. This accurate docking can ensure that the receiver 203 will not have problems such as incomplete reception or leakage caused by position deviation when receiving plasma, thereby improving the collection efficiency and accuracy of the isotope electromagnetic separation system 100 for plasma.

[0078] In some embodiments, see Figures 1 to 3 , the relative sliding distance between the first slide rail 111 and the second slide rail 121 is not less than the maximum difference in the plasma deflection diameter.

[0079] The “relative sliding distance between the first slide rail 111 and the second slide rail 121” refers to the maximum range of relative movement allowed between the first slide rail 111 and the second slide rail 121 in the isotope electromagnetic separation system 100. This distance is a parameter that measures the range of the position of the receiver 203 that the mobile component 1 can adjust in two dimensions, and is determined by factors such as the length of the first slide rail 111 and the second slide rail 121, the installation position, and the travel of the driving mechanism.

[0080] The “maximum difference in plasma deflection diameter” means that under the action of a magnetic field, plasmas of different elements will have different deflection diameters due to differences in mass-to-charge ratio and other factors. The maximum difference in plasma deflection diameter is the difference between the maximum and minimum values ​​of the deflection diameters of plasmas of various elements involved under specific element separation conditions. It reflects the widest range that the receiver 203 needs to cover in space when performing element separation to ensure that plasmas of all different deflection diameters can be collected.

[0081] The relative sliding distance between the first slide rail 111 and the second slide rail 121 is set to be not less than the maximum difference in the plasma deflection diameter. This means that the combined range of motion of the moving component 1 in the first direction (dominated by the first slide rail 111) and the second direction (dominated by the second slide rail 121) is sufficient to cover all possible ranges of plasma deflection landing points. After the plasma generated by the ion source 30 is deflected by the magnetic field in the vacuum chamber 40, no matter how big the difference in the deflection diameters of plasmas of different elements is, by driving the second fixing member 2 and the receiver 203 in their respective directions by the first slide rail 111 and the second slide rail 121, the receiver 203 can be accurately moved to the position corresponding to the plasma deflection diameter, so that the receiver 203 docks with the corresponding first fixing member 202 of the receiving device 20 and receives the plasma.

[0082] In some embodiments, see Figures 1 to 3 At least two first positioning holes 1111 are arranged on the first slide rail 111, and the first positioning holes 1111 are distributed along the length direction of the first slide rail 111. A first positioning member 113 is arranged on the first slider 112, and the first positioning member 113 can be passed through the first positioning holes 1111. The first positioning holes 1111 can at least limit the movement of the first positioning member 113 in the length direction of the first slide rail 111 to fix the distance between the receiver 203 and the ion source 30 in the first direction.

[0083] The first positioning holes 1111 are hole structures opened on the first slide rail 111 and distributed along the length direction of the first slide rail 111. The shape and size thereof are adapted to the first positioning member 113 to be used in conjunction therewith, and the main function is to provide a position for the first positioning member 113 to be inserted or passed through, thereby limiting the movement of related components in the length direction of the first slide rail 111 and playing a positioning role.

[0084] The “length direction of the first slide rail 111” refers to the straight extension direction from one end to the other end of the long strip structure of the first slide rail 111 itself. This direction determines the main movement trajectory of the first slider 112 and other components connected thereto in the first sliding assembly 11, and is also the key dimension for fixing the position subsequently by cooperating with the first positioning hole 1111 and the first positioning member 113.

[0085] The "first positioning member 113" is a component provided on the first slide 112, and usually has a certain shape and size, and can accurately match the first positioning hole 1111, such as a pin, a latch, etc. Its main function is to be inserted into the first positioning hole 1111, and to prevent the first slide 112 from continuing to slide in the length direction of the first slide rail 111 by utilizing the limiting effect of the first positioning hole 1111, thereby achieving the fixation of the distance between the receiver 203 and the ion source 30 in the first direction.

[0086] The first slide rail 111 is a basic component for guiding the first slider 112 to perform linear motion, and at least two first positioning holes 1111 are distributed on the first slide rail 111. When the first slider 112 slides on the first slide rail 111 with the second slide assembly 12 and the receiver 203 connected thereto, the first positioning member 113 on the first slider 112 can be inserted into the corresponding first positioning hole 1111 according to actual needs. Once the first positioning member 113 is inserted into a first positioning hole 1111, the first positioning hole 1111 forms a blocking restriction on the first positioning member 113 along the length direction, so that the first slider 112 can no longer move freely in the length direction of the first slide rail 111, and the distance of the receiver 203 connected to the first slider 112 relative to the ion source 30 in the first direction is fixed.

[0087] This is crucial to ensure that the receiver 203 accurately corresponds to the deflection diameters of different plasmas, because the deflection of the plasma is closely related to factors such as the distance to the ion source 30. Precise position fixation can improve the accuracy of plasma collection, reduce problems such as low collection efficiency or inaccurate separation results caused by position deviation, and improve the quality and accuracy of element separation.

[0088] In some embodiments, at least two second positioning holes 1211 are provided on the second slide rail 121, and the second positioning holes 1211 are distributed along the length direction of the second slide rail 121. A second positioning member 123 is provided on the second slider 122, and the second positioning member 123 can be passed through the second positioning hole 1211. The second positioning hole 1211 can at least limit the movement of the second positioning member 123 in the length direction of the second slide rail 121.

[0089] The second positioning holes 1211 are hole-shaped structures processed on the second slide rail 121, and are arranged in sequence along the length direction of the second slide rail 121. They have high shape and size accuracy and are compatible with the second positioning member 123. Their main purpose is to provide a matching position for the second positioning member 123 to limit the movement of the second slider 122 in the length direction of the second slide rail 121, thereby fixing the position of the receiver 203 in the second direction.

[0090] The "length direction of the second slide rail 121" refers to the extension direction of the second slide rail 121 from one end to the other end, which determines the main linear motion path of the second slider 122 in the second sliding assembly 12, and is the key dimension for the second positioning hole 1211 to play a positioning role. The precise position of the receiver 203 in the second direction is determined by limiting the movement of the second positioning member 123 in this direction.

[0091] The "second positioning member 123" is a component located on the second slider 122, usually in a columnar or pin-shaped structure, and can be matched with the second positioning hole 1211. Its function is to be inserted into the second positioning hole 1211, and with the help of the second positioning hole 1211 to constrain it in the length direction, prevent the second slider 122 from sliding further on the second slide rail 121, and then lock the position of the receiver 203 relative to the first fixing member 202 of the receiving device 20 in the second direction.

[0092] The second slide rail 121 serves as a movement guide for the second slider 122, and the plurality of second positioning holes 1211 distributed thereon provide a possibility for positioning the receiver 203 in the second direction. When the second slider 122 drives the second fixing member 2 and the receiver 203 to move on the second slide rail 121, the second positioning member 123 on the second slider 122 can be inserted into different second positioning holes 1211 as required. Once the second positioning member 123 is inserted into a second positioning hole 1211, the second slider 122 can no longer move freely in the direction due to the restriction of the second positioning member 123 by the second positioning hole 1211 in the length direction, so that the position of the receiver 203 in the second direction is fixed, so that it can accurately dock with the first fixing member 202 of the receiving device 20 and receive plasma.

[0093] With the cooperation between the second positioning hole 1211 and the second positioning member 123 , the receiver 203 can be positioned extremely accurately in the second direction, ensuring that it is accurately docked with the first fixing member 202 of the receiving device 20 .

[0094] In some embodiments, the distance between two adjacent first positioning holes 1111 is greater than or equal to 5 cm and less than or equal to 10 cm.

[0095] The specific distance between two adjacent first positioning holes 1111 is not limited here, for example, it can be 5 cm, 5.5 cm, 6 cm, 6.5 cm, 7 cm, 7.5 cm, 8 cm, 8.5 cm, 9 cm, 9.5 cm, 10 cm, etc.

[0096] In some embodiments, the distance between two adjacent second positioning holes 1211 is greater than or equal to 5 cm and less than or equal to 10 cm.

[0097] The specific distance between two adjacent second positioning holes 1211 is not limited here, for example, it can be 5 cm, 5.5 cm, 6 cm, 6.5 cm, 7 cm, 7.5 cm, 8 cm, 8.5 cm, 9 cm, 9.5 cm, 10 cm, etc.

[0098] The 5cm to 10cm spacing range of the positioning holes ensures a certain positioning accuracy while avoiding the overly complicated structures of the first slide rail 111 and the second slide rail 121 caused by too dense positioning holes. If the spacing between the positioning holes is too small, although the positioning accuracy may be higher, it will increase the processing cost, reduce the mechanical strength of the slide rail, and easily accumulate processing errors; if the spacing is too large, it may not be able to meet some element separation tasks with high precision requirements. This spacing range provides moderate flexibility for the position adjustment of the receiver 203 in the first direction and the second direction. Neither will the adjustment step length be too large due to the large spacing, resulting in the inability to accurately align the plasma landing point, nor will the adjustment be too cumbersome due to the small spacing, affecting the operating efficiency.

[0099] In some embodiments, see Figures 1 to 3 The moving component 1 includes a moving base 13, and the first sliding component 11 is arranged on the moving base 13. The moving base 13 can at least drive the first sliding component 11 to approach the first fixing member 202 along a third direction, wherein the third direction intersects with the first direction and the second direction.

[0100] The specific position of the third direction is not limited here. For the convenience of description, the third direction here is the direction shown in the accompanying drawings.

[0101] The mobile base 13 is the basic support part of the mobile assembly 1, providing stability and load-bearing capacity for the entire mobile structure. The mobile base 13 usually has a certain mass and strength, can bear the weight of the first sliding assembly 11, the second sliding assembly 12 and the receiver 203, and provide a relatively stable reference platform for their movement in space.

[0102] In addition to the first sliding assembly 11 and the second sliding assembly 12 adjusting the position of the receiver 203 in the first direction and the second direction, the mobile base 13 also has the ability to drive the first sliding assembly 11 to move along the third direction. When the receiver 203 needs to be installed on the first fixing member 202 of the receiving device 20, the first sliding assembly 11 and the second sliding assembly 12 are firstly used to perform preliminary two-dimensional plane positioning in the first direction and the second direction, so that the receiver 203 and the first fixing member 202 are roughly aligned in the horizontal or vertical plane direction. Then, the mobile base 13 drives the first sliding assembly 11 to approach the first fixing member 202 along the third direction (such as the front-to-back direction or the direction at a specific angle to the first and second directions), thereby achieving the precise docking and installation of the receiver 203 in three-dimensional space, so as to accurately receive plasma with a specific deflection diameter. For example, in an isotope electromagnetic separation system 100 with a relatively complex spatial layout, the relative positions of the ion source 30, the magnet system and the receiving device 20 may change in three dimensions. This design can ensure that the receiver 203 can smoothly reach any required position.

[0103] In some embodiments, see Figures 1 to 3 The movable base 13 includes a lifting member 131 , and the first sliding assembly 11 is disposed on the lifting member 131 . The lifting member 131 drives the first sliding assembly 11 to move along the third direction.

[0104] The lifting member 131 is a key component of the mobile base 13, and its main function is to realize the linear motion drive in the vertical direction or at a certain angle to the vertical direction (i.e., the third direction). It is usually composed of a power device (such as a motor, a hydraulic system or a pneumatic device) and a transmission mechanism (such as a screw nut pair, a gear rack or a hydraulic telescopic rod), which can convert power into precise displacement of the first sliding component 11 in the third direction, thereby driving the receiver 203 to adjust its position in the vertical dimension.

[0105] For example, two parallel lead screws are used as the transmission mechanism, which are respectively located on both sides of the lifting member 131, and the first sliding component 11 is connected to the two lead screws through a nut seat. This double lead screw structure can enhance the stability and stability of the lifting process, effectively prevent the lifting member 131 from tilting or jamming due to factors such as unilateral force or lead screw bending, and improve the accuracy and reliability of the receiver 203 in the third direction. It is particularly suitable for the lifting drive of a larger or heavier receiver 203 and related components.

[0106] For example, in addition to using a ball screw as the main vertical drive device, a linear guide is also provided on the motion path of the lifting member 131. The linear guide cooperates with the slider on the lifting member 131 to provide precise guidance for the lifting member 131, so that it can only move along a predetermined linear direction during the vertical lifting process, further reducing the possibility of shaking and offset, improving the accuracy and repeatability of the lifting movement, and being able to meet the element separation task that requires extremely high vertical position accuracy of the receiver 203.

[0107] The design of the lifting member 131 enables the receiver 203 to achieve precise position adjustment in the third direction (vertical direction or vertical direction at a specific angle), and combined with the movement in the first direction and the second direction, the receiver 203 is accurately positioned in three-dimensional space. By reasonably designing the structure of the lifting member 131 (such as using a double screw, a ball screw and a linear guide rail combination, etc.), the first sliding component 11 can be ensured to move smoothly and without jamming in the third direction, reducing the impact of vibration or shaking on the connection stability between the receiver 203 and the first fixing member 202.

[0108] In some embodiments, see Figures 1 to 3 The mobile base 13 is provided with universal wheels 132 .

[0109] The universal wheel 132 is a wheel that can be freely turned in a plane, usually installed at the bottom of the equipment, and is composed of a wheel hub, a wheel axle, a tire and a steering mechanism. Its characteristic is that the equipment can be moved in any direction without adjusting its own direction when moving, which greatly improves the maneuverability and flexibility of the equipment on the plane.

[0110] The mobile base 13 is provided with universal wheels 132, and the mobile assembly 1 in the isotope electromagnetic separation system 100 (including the first sliding assembly 11, the second sliding assembly 12, and the receiver 203 connected thereto, etc.) can be conveniently moved on the horizontal ground or other planar support surface with the help of the universal wheels 132. When the isotope electromagnetic separation system 100 is installed, debugged, maintained, or needs to be adjusted according to different experimental or production layouts, the operator can easily push the entire mobile assembly 1 to freely move it to the desired position in the plane without the need to use complex handling equipment or disassemble and reassemble the system.

[0111] In some embodiments, the mobile base 13 is provided with a counterweight 133 .

[0112] The counterweight 133 is an object with a certain mass, usually made of a metal with a high density (such as cast iron, steel, etc.). Its main function is to adjust the center of gravity and mass distribution of the entire mobile base 13 or the equipment connected thereto by increasing its own weight, thereby improving the stability and balance of the equipment when it is running or stationary.

[0113] Since the mobile assembly 1 (including the first sliding assembly 11, the second sliding assembly 12 and the receiver 203, etc.) in the isotope electromagnetic separation system 100 may shake or become unstable due to the rapid movement of the components, the change of the center of gravity or external interference (such as slight collision, air flow, etc.) during the movement, the addition of the counterweight 133 can change the overall mass distribution of the mobile base 13, reduce the center of gravity height, and make the mobile base 13 more stable when carrying the mobile assembly 1 and related components.

[0114] Next, the operation of the receiver installation device 10 is described based on a structure in which the receiving device 20 has two first fixing members 202 and two receivers 203 .

[0115] In the one-room dual-source separation mode, two receivers 203 need to work simultaneously. At the same time, to ensure isotope abundance, the distance between the two receivers 203 should not be too far, so the space is limited. The limited space does not allow two traditional receiver 203 racks to support the receivers 203 at the same time.

[0116] In the embodiment of the present application, the receiving device 20 includes two first fixing members 202 and two receivers 203 .

[0117] The first receiver 203 is first fixedly installed on the second fixing member 2, and the receiver installation device 10 is first pushed close to the first fixing member 202 to be roughly aligned. The receiver installation device 10 accurately aligns the receiver 203 with the first fixing member 202 in the first direction and the third direction through the sliding of the first slide rail 111 and the first slider 112 and the lifting of the lifting member 131, and inserts the first positioning member 113 into the first positioning hole 1111; push the second fixing member 2 to slide on the second slide rail 121 close to the first fixing member 202, and after the first fixing member 202 fixes the receiver 203, open the second fixing member 2 and evacuate the receiver installation device 10.

[0118] The receiver installation device 10 repeats the above steps to continue installing the second receiver 203.

[0119] Since the adjustment range of the first slide rail 111 and the second slide rail 121 can be set as required, and the setting of the counterweight block 133 ensures the stability of the center of gravity of the receiver installation device 10, the receiver 203 can be flexibly adjusted through the receiver installation device 10 in a narrow installation space, and the receiver 203 can be flexibly disassembled and assembled through the receiver installation device 10.

[0120] In some embodiments, the receiving device 20 includes a plurality of first fixing members 202 and a receiver 203 .

[0121] The receiver 203 can select a suitable first fixing member 202 for installation according to the deflection diameter of the plasma.
