[0036] The embodiments of the present application provide an isotope electromagnetic separation system 100, please refer to 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 mounting device 10. The ion source 30 is used to ionize the raw material to be separated to form a plasma. The vacuum chamber 40, the magnet system is arranged in the vacuum chamber 40, which is used to generate a magnetic field for deflecting the plasma. The receiving device 20 includes a body portion 201, a first fixing member 202 and a receiver 203, at least two first fixing members 202 are arranged on the body portion 201, each first fixing member 202 is arranged in a first direction away from the ion source 30, and the receiver 203 can be connected with the first fixing member 202. The receiver mounting device 10 includes a moving assembly 1 and a second fixing member 2, the second fixing member 2 is arranged on the moving assembly 1, and the receiver 203 can be preassembled on the receiver mounting device 10 through the second fixing member 2. The moving assembly 1 can at least drive the second fixing member 2 to move in a first direction and a second direction, so that the receiver 203 is selectively mounted on at least one first fixing member 202 for receiving the plasma with different deflection diameters obtained by separation, wherein the first direction intersects the second direction.

[0037] The ion source 30 is a device that can make the raw material to be separated (usually atoms or molecules) lose or gain electrons, thereby forming charged particles (ions). It is the starting point of the element separation process, which provides enough energy to ionize the raw material to produce plasma, and creates conditions for subsequent separation using magnetic field.

[0038] The vacuum chamber 40 is a sealed space with internal pressure reduced to a level far below 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 the plasma, making the deflection of the plasma in the magnetic field more accurate and stable; on the other hand, it prevents unnecessary reactions between the plasma and 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, which functions 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 Lorentz force in a magnetic field, plasmas of different mass-to-charge ratios (mass-to-charge ratio) will have different deflection radii under the same magnetic field strength, thereby realizing the separation of elements. For example, an electromagnet is a common magnet system that can control the magnetic field strength by adjusting the current size.

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

[0041] The body part 201 is the main structure of the receiving device 20, which serves to support and fix other parts. As the basic framework of the receiving device 20, it serves to carry and fix other components. The body part 201 needs to have sufficient mechanical strength and stability to ensure that its structure does not deform or displace during the entire element separation process, thereby ensuring that the receiver 203 and the first fixing part 202 can accurately perform their respective functions.

[0042] Exemplarily, the body part 201 can be made of metal material (such as aluminum alloy), and formed into a specific shape such as a cuboid or a cylindrical structure through precision machining, and its surface can be specially treated to improve wear resistance and corrosion resistance.

[0043] The first fixing part 202 is arranged on the body part 201 in the first direction to provide a mounting position for the receiver 203 and ensure its stability. A plurality of first fixing parts 202 are arranged on the body part 201 in the first direction, which mainly functions to provide a reliable connection position for the receiver 203.

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

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

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

[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 part 202 needs to have the convenience of quick installation and disassembly, so as to be able to replace or clean in time after collecting full plasma.

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

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

[0050] The moving assembly 1 can adopt various driving modes, such as linear motor driving, screw nut transmission mechanism driving, or pneumatic and hydraulic driving, etc.

[0051] The second fixing part 2 is used to connect the receiver 203 and ensure the stability of the receiver 203 during movement. Through the receiver mounting device 10, the transfer and accurate positioning of the receiver 203 can be realized, and the working efficiency and accuracy of the isotope electromagnetic separation system 100 are improved.

[0052] The structure design of the second fixing part 2 needs to match the connection part of the receiver 203, such as a metal part with a threaded hole or a bayonet, which can firmly fix the receiver 203 on the moving assembly 1 through threaded connection or clamping. During the movement of the receiver 203 with the moving assembly 1, the second fixing part 2 needs to be able to withstand the weight of the receiver 203 and the external forces such as inertia 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 operation between the second fixing part 2 and the receiver 203 should be relatively simple, so as to be able to smoothly transfer the receiver 203 from the second fixing part 2 to the first fixing part 202 after it reaches the specified position of the receiving device 20.

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

[0054] The moving assembly 1 can make the second fixing part 2 move in different directions through specific mechanical structure and power source, so as to realize the position adjustment of the receiver 203 in space, and accurately transfer it to the corresponding position of the receiving device 20 and connect with the first fixing part 202.

[0055] The mobile assembly 1 has the ability to drive the second fixing member 2 to move along 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 in the vacuum chamber 40 by the magnetic field, isotopes of different deflection diameters will reach the first fixing member 202 at different positions of the receiving device 20. The mobile assembly 1 can accurately position the receiver 203 to the corresponding first fixing member 202 according to the deflection of the isotope and the receiving requirement by driving the second fixing member 2 to move the receiver 203 along the first direction and the second direction, so as to effectively collect different isotopes of the same element.

[0056] The isotope electromagnetic separation system 100 provided in the application can accurately separate different isotopes of the same element by the principle that plasma of different mass-to-charge ratios has different deflection radii in a magnetic field. The design that the plurality of first fixing members 202 in the receiving device 20 are arranged along the first direction and the receiver 203 can be connected to the first fixing members 202 at different positions makes the system flexible to adjust the position and quantity of the receiver 203 according to different separation sequences and yield requirements. The first fixing members 202 are arranged along the first direction, so that the distance between each first fixing member 202 and the ion source 30 is different, the mobile assembly 1 can move along two directions, and the receiver 203 can be flexibly transferred to different first fixing members 202, so that the plasma of different deflection diameters obtained by separation can be received by the receiver 203 at the corresponding position, thereby improving the receiving range of the receiver 203. The arrangement that the receiver 203 is transferred to the first fixing member 202 by the second fixing member 2 reduces the installation difficulty, improves the disassembly and assembly efficiency of the receiver 203, and reduces the error caused by pure manual disassembly and assembly.

[0057] In some embodiments, referring to Figures 1 to 3 , the mobile assembly 1 comprises a first sliding assembly 11 and a second sliding assembly 12, and the second sliding assembly 12 is arranged on the first sliding assembly 11. The second fixing member 2 is arranged on the second sliding assembly 12. The first sliding assembly 11 drives the second sliding assembly 12 to move along the first direction, and drives the receiver 203 to align with one of the first fixing members 202 of the receiving device 20 in the first direction, so as to correspond to the deflection diameter of the plasma obtained by separation. The second sliding assembly 12 drives the second fixing member 2 to move along the second direction, so as to fix the receiving position of the receiver 203.

[0058] The first sliding assembly 11 is the base driving part in 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 installed thereon slide smoothly along the first direction, thereby driving the receiver 203 to adjust the position in this direction to match the receiving position corresponding to different plasma deflection diameters.

[0059] Exemplarily, the first sliding assembly 11 is provided with stroke limit switches and buffers at both ends. The stroke limit switches are used to detect the limit positions of the second sliding assembly 12 in the first direction, preventing collision accidents beyond the normal working range; the buffers play a role of buffering deceleration when the second sliding assembly 12 approaches the end of the stroke, reducing the damage of impact to the equipment. For example, hydraulic buffers or rubber buffer pads can effectively absorb impact energy.

[0060] The second sliding assembly 12 is installed on the first sliding assembly 11, which adds the movement ability in the second direction on the basis of the first direction movement provided by the first sliding assembly 11. Its main function is to drive the second fixed part 2 and the receiver 203 connected thereto to move in the second direction after the preliminary determination of the position in the first direction, so as to realize the accurate docking of the receiver 203 and the first fixed part 202 of the receiving device 20 in the plane perpendicular to the first direction, and ensure that the receiver 203 can be accurately fixed in the receiving position.

[0061] Exemplarily, the second sliding assembly 12 can be installed with a position sensor such as a grating ruler or a magnetic grating ruler, which is used to monitor the position information of the receiver 203 in the second direction in real time and feed back these information to the control system. The control system accurately controls the driving motor of the second sliding assembly 12 according to the data fed back by the sensor, realizes closed-loop control, further improves the positioning accuracy in the second direction, and the accuracy can reach micrometer level or even higher.

[0062] The mobile assembly 1 realizes the accurate movement of the receiver 203 in two-dimensional space through the first sliding assembly 11 and the second sliding assembly 12 designed in layers. First, the first sliding assembly 11 works, according to the deflection radius information of the isotope, drives the second sliding assembly 12 to move to the corresponding position in the first direction, so that the receiver 203 is in the same axis with a certain first fixed part 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 assembly 12 starts, drives the second fixed part 2 and the receiver 203 to move towards the aligned first fixed part 202 in the second direction, gradually approaches and finally fixes on the first fixed part 202, thereby completing the positioning and installation of the receiver 203, preparing to receive the plasma of a certain deflection diameter. This design makes the position adjustment process of the receiver 203 in two steps, first coarse adjustment (first direction) and then fine adjustment (second direction), which improves the accuracy and reliability of positioning.

[0063] In some embodiments, referring to Figures 1 to 3 , the first sliding assembly 11 includes a first sliding rail 111 and a first sliding block 112, and the first sliding block 112 is slidably arranged on the first sliding rail 111, and the first sliding block 112 is connected with the second sliding assembly 12.

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

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

[0066] The first sliding block 112 is a component matched with the first sliding rail 111, which is also generally made of metal and finely machined to ensure good matching precision and low friction coefficient with the first sliding rail 111.

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

[0068] The first sliding rail 111 can adopt a double-rail structure, i.e., two parallel sliding rail tracks are provided, and the first sliding block 112 is designed in a shape matching the double-rail structure, such as an H-shaped or U-shaped sliding block. Such a double-rail structure can greatly enhance the stability of the first sliding block 112 during sliding, reduce the possibility of shaking and deviation, and improve the accuracy of movement of the entire moving assembly 1 in the first direction.

[0069] The first sliding block 112 can be designed in a structure capable of adjusting the pre-tightening force. By adjusting the pre-tightening device (such as a bolt, a spring, etc.), the contact pressure and friction between the first sliding block 112 and the first sliding rail 111 can be changed, thereby to a certain extent optimizing the movement performance of the first sliding block 112.

[0070] The cooperation of the first sliding rail 111 and the first sliding block 112 provides precise linear motion guidance, so that the movement of the second sliding assembly 12 and the receiver 203 in the first direction has high directionality and accuracy. Such precise guidance can ensure that the receiver 203 accurately corresponds to the position requirements of different plasma deflection diameters in the first direction, reduces the receiving errors caused by inaccurate guidance, and improves 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, and the second sliding block 122 is slidably arranged on the second sliding rail 121, and the second sliding block 122 is connected with the second fixing member 2.

[0072] The second sliding rail 121 is a component for guiding in the second sliding assembly 12, and is usually a long strip-shaped structure with specific shape and accuracy requirements, and is generally made of metal materials such as aluminum alloy and steel.

[0073] The second sliding rail 121 is used to determine the movement trajectory of the second sliding block 122 in the second direction, and provides a precise linear motion guidance path for the second fixing member 2 and the receiver 203 connected thereto, so as to ensure that they can accurately adjust the position in a plane perpendicular to the first direction.

[0074] The second sliding block 122 is a component matched with the second sliding rail 121 and capable of sliding thereon, and is also made of metal materials, and its shape and size are matched with the track shape of the second sliding rail 121, so as to ensure good cooperation accuracy and low friction coefficient.

[0075] The second sliding block 122, as a key element connecting the second fixing member 2 and the second sliding rail 121, transmits the guiding action of the second sliding rail 121 to the second fixing member 2, so that the second fixing member 2 can drive the receiver 203 to move stably and accurately in the second direction, so as to be docked and fixed 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 second slide rail 121 is connected by a high-precision connecting 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 some slide rails are damaged, which can be handled more flexibly.

[0077] The design of the second slide rail 121 and the second slide block 122 enables the receiver 203 to make precise position adjustment in the second direction, thereby achieving precise docking with the first fixed part 202. This precise docking can ensure that the receiver 203 does not have incomplete reception or leakage problems caused by positional deviation when receiving the plasma, thereby improving the collection efficiency and accuracy of the isotope electromagnetic separation system 100 on the plasma.

[0078] In some embodiments, referring to Figures 1 to 3 The relative sliding distance of the first slide rail 111 and the second slide rail 121 is not less than the maximum difference of the plasma deflection diameters.

[0079] The relative sliding distance of the first slide rail 111 and the second slide rail 121 refers to the maximum range of relative movement between the first slide rail 111 and the second slide rail 121 allowed in the isotope electromagnetic separation system 100. This distance is a parameter for measuring the range of position adjustment of the receiver 203 in two dimensions by the moving assembly 1, which is determined by the length, installation position, and stroke of the driving mechanism of the first slide rail 111 and the second slide rail 121.

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

[0081] The relative sliding distance of the first sliding rail 111 and the second sliding rail 121 is set to be not less than the maximum difference of the plasma deflection diameters. This means that the movement range of the moving assembly 1 in the first direction (dominated by the first sliding rail 111) and the second direction (dominated by the second sliding rail 121) is sufficient to cover the range of all possible plasma deflection landing points. When the plasma generated by the ion source 30 is deflected in the vacuum chamber 40 by the magnetic field, no matter how large the difference in the deflection diameters of different element plasmas is, by driving the second fixed part 2 and the receiver 203 in the respective directions through the first sliding rail 111 and the second sliding rail 121, the receiver 203 can be accurately moved to the position corresponding to the plasma deflection diameter, so that the receiver 203 is docked with the corresponding first fixed part 202 of the receiving device 20 and receives the plasma.

[0082] In some embodiments, referring to Figures 1 to 3 , at least two first positioning holes 1111 are arranged on the first sliding rail 111, which are distributed along the length direction of the first sliding rail 111. A first positioning part 113 is arranged on the first sliding block 112, which can be inserted into or passed through the first positioning hole 1111. The first positioning hole 1111 can at least limit the movement of the first positioning part 113 in the length direction of the first sliding rail 111, so as to fix the distance of the receiver 203 from the ion source 30 in the first direction.

[0083] The first positioning hole 1111 is a hole structure arranged on the first sliding rail 111 and distributed along the length direction of the first sliding rail 111. Its shape and size are adapted to the first positioning part 113 to be used subsequently. The main function is to provide a position for the first positioning part 113 to insert or pass through, so as to limit the movement of the relevant parts in the length direction of the first sliding rail 111 and play a positioning role.

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

[0085] The first positioning part 113 is a component arranged on the first sliding block 112, which usually has a certain shape and size and can accurately cooperate with the first positioning hole 1111, such as a pin, a latch or the like. Its main role is to be inserted into the first positioning hole 1111 and use the limiting action of the first positioning hole 1111 to prevent the first sliding block 112 from continuing to slide in the length direction of the first sliding rail 111, thereby fixing the distance of the receiver 203 from the ion source 30 in the first direction.

[0086] The first slide rail 111 is a base component guiding the linear motion of the first slider 112, and at least two first positioning holes 1111 are distributed on the first slide rail 111. When the first slider 112 with the second sliding assembly 12 and the receiver 203 connected thereto slides on the first slide rail 111, 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 certain first positioning hole 1111, since the first positioning hole 1111 forms a blocking limit to the first positioning member 113 in the length direction, the first slider 112 cannot move randomly in the length direction of the first slide rail 111, and then the distance of the receiver 203 relative to the ion source 30 in the first direction is also fixed.

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

[0088] In some embodiments, at least two second positioning holes 1211 are arranged on the second slide rail 121, and the second positioning holes 1211 are distributed along the length direction of the second slide rail 121. The second slider 122 is provided with a second positioning member 123, and the second positioning member 123 can be arranged in 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 hole 1211 is a hole structure machined on the second slide rail 121 and arranged and distributed in sequence along the length direction of the second slide rail 121. It has high shape and size precision and is matched with the second positioning member 123. Its 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 realizing the fixation of 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. By limiting the movement of the second positioning member 123 in this direction, the accurate position of the receiver 203 in the second direction is determined.

[0091] The second positioning member 123 is a component on the second sliding block 122, usually in a columnar or pin-like structure, which can cooperate with the second positioning hole 1211. Its function is to be inserted into the second positioning hole 1211, and by virtue of the lengthwise constraint of the second positioning hole 1211, to prevent the second sliding block 122 from further sliding on the second sliding rail 121, and thus to lock the position of the receiver 203 in the second direction relative to the first fixed member 202 of the receiving device 20.

[0092] The second sliding rail 121 serves as the movement guide basis for the second sliding block 122, and the multiple second positioning holes 1211 distributed on it make it possible for the receiver 203 to be positioned in the second direction. When the second sliding block 122 moves with the second fixed member 2 and the receiver 203 on the second sliding rail 121, the second positioning member 123 on the second sliding block 122 can be inserted into different second positioning holes 1211 as needed. Once the second positioning member 123 is inserted into a certain second positioning hole 1211, the second sliding block 122 cannot move freely in that direction any more due to the lengthwise constraint of the second positioning hole 1211 on the second positioning member 123, so that the position of the receiver 203 in the second direction is fixed, thus enabling it to accurately dock with the first fixed member 202 of the receiving device 20 and receive plasma.

[0093] By virtue of the cooperation between the second positioning hole 1211 and the second positioning member 123, the receiver 203 can be extremely accurately positioned in the second direction, ensuring that it accurately docks with the first fixed 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 and can be, for example, 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 and can be, for example, 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 positioning hole spacing range of 5cm to 10cm ensures certain positioning accuracy while avoiding the overly complex structure of the first slide rail 111 and the second slide rail 121 caused by too dense positioning holes. If the positioning hole spacing is too small, although the positioning accuracy can be higher, the processing cost can be increased, the mechanical strength of the slide rail can be reduced, and the processing errors can be easily accumulated; and if the spacing is too large, some element separation tasks with high accuracy requirements can not be met. This spacing range provides moderate flexibility for the position adjustment of the receiver 203 in the first direction and the second direction. Neither the adjustment step is too large due to the too large spacing, nor the adjustment is too tedious due to the too small spacing, which affects the operation efficiency.

[0099] In some embodiments, referring to Figures 1 to 3 , the moving assembly 1 includes a moving base 13, and the first sliding assembly 11 is arranged on the moving base 13. The moving base 13 can at least drive the first sliding assembly 11 to move towards the first fixed part 202 in a third direction. The third direction intersects 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 drawings.

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

[0102] In addition to the position adjustment of the receiver 203 in the first direction and the second direction by the first sliding assembly 11 and the second sliding assembly 12, the moving base 13 also has the ability to drive the first sliding assembly 11 to move in the third direction. When it is necessary to install the receiver 203 on the first fixed part 202 of the receiving device 20, first, the preliminary two-dimensional in-plane positioning in the first direction and the second direction is performed by the first sliding assembly 11 and the second sliding assembly 12, so that the receiver 203 is roughly aligned with the first fixed part 202 in the horizontal or vertical plane direction. Then, the moving base 13 drives the first sliding assembly 11 to move towards the first fixed part 202 in the third direction (such as the front-back direction or a direction at a specific angle with the first and second directions), so as to realize the accurate butt joint and installation of the receiver 203 in the three-dimensional space, so as to accurately receive the 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 can change in three dimensions. This design can ensure that the receiver 203 can smoothly reach any required position.

[0103] In some embodiments, referring to Figures 1 to 3 , the mobile base 13 comprises a lifting member 131, and the first sliding assembly 11 is arranged on the lifting member 131, and the lifting member 131 drives the first sliding assembly 11 to move in 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 driving of linear motion in the vertical direction or at a certain angle with 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 assembly 11 in the third direction, thereby driving the receiver 203 to adjust the position in the vertical dimension.

[0105] Exemplarily, two parallel screws are used as transmission mechanisms, which are respectively located on both sides of the lifting member 131, and the first sliding assembly 11 is connected with the two screws through a nut seat. This double screw structure can enhance the stability and smoothness of the lifting process, effectively prevent the inclination or jamming of the lifting member 131 caused by factors such as unilateral force or screw bending, improve the accuracy and reliability of the movement of the receiver 203 in the third direction, and is particularly suitable for the lifting drive of a larger or heavier receiver 203 and related components.

[0106] Exemplarily, on the movement path of the lifting member 131, in addition to using a ball screw as the main vertical driving device, a linear guide rail is also equipped. The linear guide rail cooperates with the slider on the lifting member 131 to provide accurate guidance for the lifting member 131, so that it can only move in the predetermined straight line direction during the vertical lifting process, further reducing the possibility of shaking and deviation, improving the accuracy and repeatability of the lifting movement, and being able to meet the element separation task with high requirements for the vertical position accuracy of the receiver 203.

[0107] The design of the lifting member 131 enables the receiver 203 to realize accurate position adjustment in the third direction (vertical direction or vertical direction at a certain angle), and in combination with the movement in the first direction and the second direction, realizes the accurate positioning of the receiver 203 in the three-dimensional space. By reasonably designing the structure of the lifting member 131 (such as using double screws, ball screws and linear guide rails in combination), the movement of the first sliding assembly 11 in the third direction can be smooth and without jamming, and the influence of vibration or shaking on the connection stability of the receiver 203 and the first fixed member 202 can be reduced.

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

[0109] The universal wheel 132 is a kind of wheel that can freely steer in a plane, usually installed at the bottom of the device, which is composed of a hub, an axle, a tire and a steering mechanism. Its feature is that it can make the device move in any direction without adjusting its own direction when moving, greatly improving the mobility and flexibility of the device in the plane.

[0110] The mobile base 13 is provided with universal wheels 132, and the mobile assembly 1 (including the first sliding assembly 11, the second sliding assembly 12 and the receiver 203 connected thereto) in the isotope electromagnetic separation system 100 can be conveniently moved above the horizontal ground or other plane support surface by means of the universal wheels 132. When the isotope electromagnetic separation system 100 is installed, debugged, maintained or needs to be adjusted in position according to different experimental or production layouts, the operator can easily push the entire mobile assembly 1 to freely move in the plane to the desired position without the need for complex handling equipment or disassembly and reassembly of 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 high density (such as cast iron, steel, etc.). Its main function is to adjust the center of gravity position and mass distribution of the entire mobile base 13 or the device connected thereto by increasing its own weight, thereby improving the stability and balance of the device when running or stationary.

[0113] Since the mobile assembly 1 (including the first sliding assembly 11, the second sliding assembly 12 and the receiver 203) in the isotope electromagnetic separation system 100 may shake or become unstable during movement due to rapid movement of components, changes in center of gravity or external disturbances (such as slight collisions, air flow effects, etc.). The addition of the counterweight 133 can change the overall mass distribution of the mobile base 13, lower 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 receiver mounting device 10 is described in operation with the structure that the receiving device 20 has two first fixing members 202 and two receivers 203.

[0115] In a single-chamber dual-source separation mode, two receivers 203 need to work simultaneously, and at the same time, the distance between the two receivers 203 should not be too far to ensure the isotopic abundance, so the space is limited. Limited space does not allow the use of two traditional receiver 203 racks to support the receiver 203 at the same time.

[0116] In the embodiments 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 to be approximately aligned with the first fixing member 202. The receiver installation device 10 is used to accurately align the receiver 203 with the first fixing member 202 in the first direction and the third direction through the sliding of the first sliding rail 111 and the first sliding block 112 and the lifting of the lifting member 131, and the first positioning member 113 is inserted into the first positioning hole 1111. The second fixing member 2 is pushed to slide on the second sliding rail 121 to be close to the first fixing member 202, and after the first fixing member 202 fixes the receiver 203, the second fixing member 2 is opened and the receiver installation device 10 is removed.

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

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

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

[0121] The receiver 203 can be installed according to the deflection diameter of the plasma.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application is included in the protection scope of the present application.
