Description

Technical Field

[0001] The present invention belongs to the technical field related to reactant collection, and in particular relates to a multi-nucleon transfer reaction transmission device and a multi-nucleon transfer reaction equipment. Background Art

[0002] The superheavy stable island nuclides produced by multi-nucleon transfer have a large cross section, but their reaction products have a large angular distribution and are difficult to collect. On the one hand, according to physical calculations, the central angle distribution of the multi-nucleon transfer reaction products is in the range of 30° to 60°, and has a large angular emittance.

[0003] In the existing technology, the collection of multi-nucleon transfer reactants is often limited to fixed pipes, although the use of bellows with some connecting rod-like devices can be used for small-range circular rotation, and then small-range lifting and multi-angle collection of nuclei. However, for the collection of multi-nucleon transfer reaction products at large angles, there are still a lot of nuclei that cannot be effectively collected. Furthermore, for some experiments analyzing the distribution law of multi-nucleon transfer products, devices that cannot collect nuclei emitted at a wider angle cannot draw more scientific and valuable experimental conclusions. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a multi-nucleon transfer reaction transmission device and a multi-nucleon transfer reaction equipment. By setting a deformation chamber, the deformation chamber and the collection chamber can be deflected at a certain angle to achieve multi-angle collection and transmission to the next-level device when multi-angle reactants are generated by cooperating with the rotating component during rotation.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] In a first aspect, the present invention provides a multi-nucleon transfer reaction transmission device, comprising:

[0007] The machine platform is provided with a rotating platform and a rotating assembly, and the rotating platform and the rotating assembly are respectively arranged on both sides of the machine platform;

[0008] The rotating assembly comprises a rotating plate and a driving motor, wherein one end of the rotating plate is rotatably connected to the rotating table, and the driving motor is arranged at the other end of the rotating plate, and the driving motor is drivingly connected to the rotating assembly so that the rotating plate rotates along the rotating table;

[0009] The pipeline assembly includes a fixed chamber, a deformation chamber, and a collecting chamber which are connected in sequence. The fixed chamber is fixedly arranged on the machine platform, and the collecting chamber is fixedly arranged on the rotating plate. When the collecting chamber rotates with the rotating assembly, the reactants generated in the fixed chamber are output to the collecting chamber through the deformation chamber.

[0010] A rotating assembly is arranged on the machine platform so that the rotating assembly can interact with the rotating assembly, and driven by the rotating assembly, the pipeline assembly installed on the rotating assembly is driven to rotate, so that the deformation chamber is further deformed and drives the collection chamber to rotate, so that the pipeline assembly can partially rotate, thereby realizing the collection and transmission of multi-nucleon transfer reaction products at multiple angles, and the multi-nucleon transfer products are sent from the collection chamber to the next-level equipment to realize efficient collection of multi-nucleon transfer reactants, and at the same time, it can also provide a multi-angle reactant collection method for the test experimental device of multi-nucleon transfer reactants.

[0011] In some embodiments, a preset target axis is provided in the fixed chamber, and when the preset target axis is installed in the target chamber and the fixed chamber, the target point is provided on the preset target axis; the top-view direction of the transmission device of the multi-nucleon transfer reaction is set as a first direction, and in the first direction view, the preset target axis forms a preset target axis point.

[0012] A preset target axis is set in the fixed chamber. The preset target axis is a virtual position where the target point in the target chamber is installed when the target chamber and the fixed chamber are installed when the fixed chamber is designed. The design of this position can provide a reference point for most structures in the multi-nucleon transfer reaction collection device, and set the top view direction as the first direction. The first direction view can make the emission direction and angle of multi-angle multi-nucleon transfer reactants more intuitive. When designing the transmission device of the multi-nucleon transfer reaction, the rotation angle is designed according to the first direction, and combined with the target axis point as a reference point, it can be more intuitive and fit the angle generated by the actual multi-nucleon transfer reactants.

[0013] In some embodiments, the central axis of the rotating stage is consistent with the preset target axis position.

[0014] The central axis of the rotating table is consistent with the preset target axis position to further limit the position of the preset target axis, so that when rotating, when observed in the first direction, the position of the preset target axis point formed by the target axis is used as the rotation center for rotation, thereby more closely fitting the actual generation angle of the multi-nucleon transfer reactant during collection.

[0015] In some embodiments, the collection chamber is provided with an output port, and in the first direction, a preset target axis point forms an angle of 26° with both sides of the output port.

[0016] The purpose of this method is that the next-level collection and focusing at the output port of the multi-nuclear reactant collection device is usually completed by a superconducting solenoid. Due to the excitation intensity and aperture limitation of the superconducting solenoid, the output reactant beam at the output port should be observed in the first direction, with the line connecting the target axis point and the midpoint of the output port as the 0° line, and the reactant beam wave deflected ≤±13° in width, that is, the preset target axis point forms an angle of 26° with the lines connecting the two sides of the output port.

[0017] In some embodiments, the rotating assembly includes an arc-shaped rack and an arc-shaped guide rail, which are arranged adjacent to each other; and in a first direction, the arc-shaped rack and the arc-shaped guide rail are arranged on a circle with a preset target axis point as the center; the driving motor is provided with a driving gear, which is meshed with the arc-shaped rack; a sliding block is provided on the lower surface of the rotating plate, and the sliding block is slidably arranged on the arc-shaped guide rail.

[0018] As a preferred implementation method, the arc-shaped rack is arranged adjacent to the arc-shaped guide rail so that when the rotating plate is driven to rotate, it rotates synchronously on the arc-shaped rack and the arc-shaped guide rail, so as to realize the rotation of the pipeline assembly on the rotating plate at a certain angle, thereby satisfying the device's collection of multi-nuclear reaction products at multiple angles.

[0019] In some embodiments, the rotating assembly also includes an arc-shaped resistor, which is arranged on one side of the arc-shaped rack. The rotating plate is also provided with a feeler, which is arranged adjacent to the drive motor. One end of the feeler is connected to the rotating plate, and the other end abuts against the arc-shaped resistor.

[0020] In order to further understand the rotation angle of the rotating plate when it rotates, an arc-shaped resistor is also set, and a feeler is set at the rotating plate. The feeler abuts against the arc-shaped resistor to play a function similar to a sliding rheostat, so that when it rotates, the current rotation angle can be inferred by the change in resistance value.

[0021] In some embodiments, a control component is also included, which includes a resistance detection element and a control unit; one end of the resistance detection element is connected to the contact angle, and the other end is connected to the arc resistor, and the resistance detection element feeds back data to the control unit to determine the rotation angle through resistance changes.

[0022] The control component detects the test resistance value generated between the feeler and the arc resistor through the resistance detection element, infers the current rotation angle, and feeds it back to the control unit. The control unit can control the rotation angle according to the current multi-nucleon transfer reactant collection situation to more efficiently collect and transmit the product to the next level equipment.

[0023] In some embodiments, the fixed chamber and the deformation chamber are connected by welding, a flange structure is provided between the deformation chamber and the collection chamber, and the deformation chamber and the collection chamber are connected by the flange structure.

[0024] By fixing and disassembling the flange structure, the collection chamber can be changed to adapt to the size of the collection chamber required by the next-level equipment of various experiments.

[0025] In some embodiments, the deformation chamber is a bellows.

[0026] The compression, stretching and bending characteristics of the bellows are used to realize the rotation of the collection chamber, thereby collecting and transmitting multi-angles of multi-nucleon transfer reactants.

[0027] In the second aspect, the present invention proposes a multi-nucleon transfer reaction device, comprising: the multi-nucleon reactant collection device, target chamber device, and detection device proposed in the first aspect; the target chamber device, the multi-nucleon transfer reaction transmission device, and the detection device are connected in sequence, and a guide channel is formed inside to realize the detection of the reactants.

[0028] The target chamber is fixedly installed, and the upper-level device emits a secondary beam wave toward the fixed chamber to hit the target point and emit reactants, which are then transferred to the lower-level equipment after being transmitted through the deformation chamber and the collection chamber.

[0029] The beneficial effects of a multi-nucleon transfer reaction transmission device and a multi-nucleon transfer reaction equipment of the present invention are:

[0030] By arranging a rotating table and a rotating assembly on the machine, the driving motor is connected to the rotating assembly, so that the rotating plate rotates along the rotating table. On this basis, a pipeline assembly is arranged, which includes a fixed chamber, a deformation chamber, and a collecting chamber connected in sequence. The fixed chamber is fixedly arranged on the machine, and the collecting chamber is fixedly arranged on the rotating plate, so that the collecting chamber rotates to collect the reactants emitted by the fixed chamber. Through the above method, the reactants of multi-nucleon transfer can be collected and transmitted at multiple angles, and the multi-nucleon transfer products can be sent to the next-level equipment through the collecting chamber, so as to realize the efficient collection of multi-nucleon transfer reactants, and at the same time, it can also provide a multi-angle reactant collection method for the test experimental device of multi-nucleon transfer reactants.

[0052] Embodiment 1:

[0053] like Figure 1 As shown, this embodiment provides a multi-nucleon transfer reaction transmission device, including:

[0054] The machine platform 100 is provided with a rotating platform 110 and a rotating assembly 120, and the rotating platform 110 and the rotating assembly 120 are respectively arranged on both sides of the machine platform 100;

[0055] The rotating assembly includes a rotating plate 210 and a driving motor 220. One end of the rotating plate 210 is rotatably connected to the rotating table 110. The driving motor 220 is disposed at the other end of the rotating plate 210. The driving motor 220 is rotatably connected to the rotating assembly 120 so that the rotating plate 210 rotates along the rotating table 110.

[0056] The pipeline assembly includes a fixed chamber 310, a deformation chamber 320, and a collecting chamber 330 connected in sequence. The fixed chamber 310 is fixedly set on the machine 100, and the collecting chamber 330 is fixedly set on the rotating plate 210. When the collecting chamber 330 rotates with the rotating assembly, the reactants generated in the fixed chamber 310 are output to the collecting chamber 330 through the deformation chamber 320.

[0057] Specifically, the machine 100 is set. Since the rotation is usually in the form of an angle rotation with a fixed point as the center of a circle and the other side rotating at an angle, the width of one side of the rotating assembly 120 set on the machine 100 can be extended so that the rotating assembly 120 can be installed, and the other side can be set as a fixed side without extending both sides. The machine 100 is provided with multiple fixing holes to achieve multiple structures such as screw bolt fixation. In order to provide a rotating platform, a rotating assembly is further set. Its purpose is to be linked with the rotating assembly 120 of the rotating table 110, so that when the rotating assembly 120 is fixed on the machine 100 and does not rotate, it rotates through the rotating assembly, and a rotating plate 210 is further set to achieve the rotation of the rotating plate 210 when the machine 100 is stationary, so as to achieve the rotation of the pipeline assembly set on the rotating plate 210. Since the rotation is usually in the form of fixing one side and freely rotating on the other side, one side of the rotating plate 210 is rotatably fixed on the machine 100, and the other side interacts with the rotating component 120 of the machine 100, thereby realizing rotation around a point. Furthermore, a rotating bearing can be set on the fixed side of the rotating plate 210, and the shaft core of the rotating bearing is rotatably clamped on the machine 100, and further one side of the rotating plate 210 is clamped on the rotating bearing and rotates with the rotating bearing, thereby realizing a form in which one side of the rotating plate is rotatably fixed and the other side can rotate freely.

[0058] Furthermore, in order to realize the multi-angle recovery of multi-nucleon transfer reactants, a pipeline assembly is set on the rotating plate, and the fixed chamber 310, the deformation chamber 320, and the collection chamber 330 are closed and connected in sequence, and a vacuum closed chamber is formed inside, so that the reactants produced by the target shooting in the fixed chamber 310 flow to the deformation chamber 320 and the collection chamber 330, and flow from the collection chamber 330 to the next level of equipment. Since the products are usually produced at multiple angles when shooting in the fixed chamber 310, in order to prevent the angle of the reactants from further expanding, the fixed chamber 310 is usually not rotated to avoid the product from further increasing the emission angle to produce more uncertainty. Therefore, the fixed chamber 310 is fixed on the machine 100 and is set on the side away from the rotating assembly 120. The specific fixing method can be to set up multiple brackets, and the two supporting feet of the brackets are respectively supported on both sides of the rotating plate 210, so that the rotating plate 210 can swing in the space formed between the two supporting feet of the brackets. This method not only fixes the fixed chamber 310, but also can prevent the rotating assembly 120 and the rotating assembly from being disengaged due to excessive rotation by limiting the angle of rotation of the supporting feet. Preferably, there are two brackets, and the two brackets are arranged at intervals to support different parts of the fixed part, thereby improving the stability of the support. At the same time, the two supporting feet of the bracket are fixed on the machine 100, and the supporting part can be designed according to the curvature of the fixed chamber 310, so that the fixed chamber 310 abuts against the supporting part, and further can be bonded when abutting, thereby improving the supporting effect of the bracket on the fixed chamber 310.

[0059] Furthermore, the deformation chamber 320 and the collection chamber 330 in the pipeline assembly usually need to rotate to collect the reactants of the multi-nucleon transfer emitted by the fixed chamber 310, so it is necessary to provide a driving force for rotation through the rotating plate 210. The rotation of the collection chamber 330 can drive the deformation of the deformation chamber 320 to match the deformation and compression of the pipeline caused by the rotation of the collection chamber 330. Therefore, the collection chamber 330 and the rotating plate 210 can be fixed to realize the rotation of the collection chamber 330 by the rotating plate 210, so that the multi-nucleon transfer product can be collected in a manner of deformation and matching of the deformation chamber 320. Specifically, a rotating bracket can be set between the collection chamber 330 and the rotating plate, and one end of the rotating bracket is fixed to the rotating plate by screws and nuts, and the other end is abutted, preferably bonded, and\or clamped, and fixed to the bottom of the collection chamber 330, so that the collection chamber 330 rotates with the rotating plate 210. Preferably, two rotating brackets are set, and the rotating brackets are arranged at intervals so that the rotating brackets support different parts of the collection chamber 330 to improve the stability of the support.

[0060] By arranging a rotating assembly 120 on the machine 100, the rotating assembly can interact with the rotating assembly 120, and driven by the rotating assembly, the pipeline assembly installed on the rotating assembly is driven to rotate, so that the deformation chamber 320 is further deformed and drives the collection chamber 330 to rotate, so that the pipeline assembly can partially rotate, thereby realizing the collection and transmission of multi-nucleon transfer reactants at multiple angles, and the multi-nucleon transfer products are sent from the collection chamber 330 to the next-level equipment, thereby realizing efficient collection of multi-nucleon transfer reactants, and at the same time, it can also provide a multi-angle reactant collection method for the test experimental device of multi-nucleon transfer reactants.

[0061] Embodiment 2:

[0062] like Figure 2 to Figure 6 As shown, based on Example 1, this embodiment further illustrates and optimizes the structure proposed in Example 1.

[0063] In some embodiments, a preset target axis 311 is set in the fixed chamber 310. When the preset target axis 311 is installed in the target chamber and the fixed chamber 310, the target point is set on the preset target axis 311; the top-view direction of the transmission device of the multi-nucleon transfer reaction is set as the first direction a, and the preset target axis 311 forms a preset target axis point 312 when viewed from the first direction a.

[0064] Specifically, the preset target axis 311 is a virtual position, so that when designing, the preset target axis 311 can be used as a reference for the emission angle of the reactants of the multi-nucleon transfer, so as to further design the entire device. The preset target axis 311 is the preset target axis point 312 when observed in the first direction a from a top view. Furthermore, when designing the device, for the convenience of design, a coordinate system is usually established in the first direction a with the preset target axis point 312 as the origin. The beam direction input to the fixed chamber 310 by the upper-level equipment is the X direction, and the direction perpendicular to the X direction is the Y direction. According to the coordinate system and the actual radiation angle, the multi-nucleon transfer reactants are emitted in the first quadrant and the second quadrant, and are more concentrated in the first quadrant at the position with a slope of 30° to 60°. Figure 3 to Figure 5 As shown, according to this method, the fixed chamber 310 can be further set to a square shape, and the fixed chamber 310 is a square shape under the first direction a viewing angle, and the connection port of the fixed chamber 310 and the deformation chamber 320 is set at an oblique angle, so that the preset target axis point 312 and the axis of the deformation chamber 320 when not deformed have an oblique angle of 45° with the X axis. The beneficial effect of this method is that since the production angles of the common multi-nucleon transfer reactants are more concentrated at 30° and 60°, and 45° is between the angle range, the collection chamber 330 only needs to rotate ±15° to complete the coverage within the angle range. This method can also avoid the problem of complex design of the entire device and large space occupation caused by the excessive rotation angle of the entire device.

[0065] A preset target axis 311 is provided in the fixed chamber 310. The preset target axis 311 is a virtual position for installing the target point in the target chamber when the target chamber and the fixed chamber 310 are installed when the fixed chamber 310 is designed. The design of this position can provide a reference point for most structures in the transmission device of the multi-nucleon transfer reaction, and set the top view direction as the first direction a. The view in the first direction a can make the emission direction and angle of the multi-angle multi-nucleon transfer reactants more intuitive. When designing the transmission device of the multi-nucleon transfer reaction, the rotation angle is designed according to the first direction a, and combined with the preset target axis point 312 as a reference point, it can be more intuitive and fit the angle generated by the actual multi-nucleon transfer reactants.

[0066] In some embodiments, the central axis of the rotating stage 110 is aligned with the preset target axis 311 .

[0067] Specifically, the central axis of the rotating table 110 is at the preset target axis 311. It can be understood that the central axis of the rotating table 110 is at the position where the space coincides with the fixed chamber 310, that is, the preset target axis 311. To ensure that the rotating axis always passes through the target point; preferably, when designing the fixed chamber 310, the relationship with the deformation chamber 320 is considered. In actual use, at the first direction a viewing angle, the length between the deformation chamber 320 and the target axis point can be set to 87 mm.

[0068] The central axis of the rotating table 110 is consistent with the position of the preset target axis 311 to further limit the position of the preset target axis 311, so that when rotating, when observed in the first direction a, the position of the preset target axis point 312 formed by the target axis is used as the rotation center for rotation, thereby more closely fitting the actual generation angle of the multi-nucleon transfer reactant during collection.

[0069] In some embodiments, the collection chamber 330 is provided with an output port, and in the first direction a, the preset target axis point 312 forms an angle of 26° with both sides of the output port.

[0070] Specifically, the angle is a reactant beam wave with a width of ≤±13° deflected from the first direction a, with the line connecting the target axis point and the midpoint of the output port as the 0° line, that is, the preset target axis point 312 and the lines connecting the two sides of the output port form a 26° angle. The angle is limited by the solenoid receiving angle. In actual calculations, it is generally between ±10° and ±12°, and in order to reserve space, the ±13° setting is selected. It should be noted that the angle definition method is different from the above-mentioned coordinate system definition method. This method is only a reference angle set for the design of the size of the collection chamber 330, that is, the line connecting the preset target axis point 312 and the midpoint of the output port as the 0° line is used as the reference axis, and the preset target axis point 312 and the lines connecting the two sides of the output port are used as the deflection angle to determine the size of the collection chamber 330. Further, the axis of the collection chamber 330 and the origin can be rotated between 30° and 60°, and when it is rotated to the extreme angles of 30° and 60°, since the axis is aligned with the positions of 30° and 60° at this time, it can be understood that the space of the other half of the collection chamber 330 exceeds 30° and 60°, that is, the range covered by the collection chamber 330 is actually 15° to 75°. Preferably, according to the above method, according to the limitation of the solenoid acceptance angle, in actual application, the inner diameter of the collection chamber 330 is 318 mm.

[0071] The purpose of this method is that the next-level collection and focusing at the output port of the multi-nuclear reactant collection device is usually completed by a superconducting solenoid. Due to the excitation intensity and aperture limitation of the superconducting solenoid, the output reactant beam at the output port should be observed in the first direction a, with the line connecting the target axis point and the midpoint of the output port as the 0° line, and the reactant beam wave deflected ≤±13° in width, that is, the preset target axis point 312 forms an angle of 26° with the lines connecting the two sides of the output port.

[0072] In some embodiments, the rotating assembly 120 includes an arcuate rack 240 and an arcuate guide rail 250, which are adjacent to each other; and in the first direction a, the arcuate rack 240 and the arcuate guide rail 250 are arranged on a circle with a preset target axis point 312 as the center; the driving motor 220 is provided with a driving gear 230, which is meshed with the arcuate rack 240; a sliding block is provided on the lower surface of the rotating plate 210, and the sliding block is slidably arranged on the arcuate guide rail 250.

[0073] Specifically, in some preferred embodiments, the arc-shaped rack 240 and the arc-shaped guide rail 250 are selected as the rotating assembly 120, which can be fixed on the machine table 100 by bonding or fixing with screws and nuts. The arc-shaped rack 240 and the arc-shaped guide rail 250 are arranged adjacent to each other. At the same time, from the first direction a viewing angle, the arc-shaped rack 240 and the arc-shaped guide rail 250 are arranged on a circumference with the preset target axis point 312 as the center of the circle, and are slidably arranged on the arc-shaped guide rail 250 by the fixed sliding block at the bottom of the rotating plate 210. At the same time, the driving gear 230 fixed on the driving motor 220 of the rotating plate 210 is meshed with the arc-shaped rack 240, so that the rotating plate 210 slides synchronously on the arc-shaped guide rail 250 and the arc-shaped rack 240. It can be understood that the sliding block is also arranged to be arc-shaped to match the arc-shaped guide rail 250. Furthermore, the arc guide rail 250 can be set longer than the arc rack 240 to prevent the risk of excessive deflection, gear disengagement and complete derailment of the rotating plate 210. Preferably, in the first direction a, the radius of the circle formed by the target axis point and the arc guide rail 250 is 500 mm.

[0074] As a preferred embodiment, the arc rack 240 is arranged adjacent to the arc guide rail 250, so that when the rotating plate 210 is driven to rotate, it rotates synchronously on the arc rack 240 and the arc guide rail 250, so as to realize the rotation of the pipeline assembly on the rotating plate 210 at a certain angle, thereby satisfying the device's collection of multi-nuclear reaction products at multiple angles.

[0075] In some embodiments, the rotating assembly 120 also includes an arc-shaped resistor 440, which is arranged on one side of the arc-shaped rack 240. The rotating plate 210 is also provided with a tentacle 430, which is arranged adjacent to the driving motor 220. One end of the tentacle 430 is connected to the rotating plate 210, and the other end abuts against the arc-shaped resistor 440.

[0076] Specifically, the arc resistor 440 is arranged on one side of the arc rack 240, and in the first direction a view, the arc resistor 440 is also arranged in a manner that the arc resistor 440 is arranged on the circumference according to the target axis point as the center of the circle. At the same time, a feeler 430 is arranged in coordination, one end of the feeler 430 abuts against the arc resistor 440 to slide, and the other end is fixed on the rotating plate 210, so that when the rotating plate 210 rotates, the feeler 430 also rotates synchronously therewith. Further, one end of the detection circuit can be connected to one end of the arc resistor 440, and the other end can be connected to one end of the feeler 430, so that when sliding, the resistance also changes accordingly, which can be further converted into the angle of rotation.

[0077] In order to further understand the rotation angle of the rotating plate 210 when it rotates, an arc-shaped resistor 440 is also provided, and a feeler 430 is provided at the rotating plate 210, the feeler 430 abuts against the arc-shaped resistor 440 to play a function similar to a sliding rheostat, so that when it rotates, the current rotation angle can be inferred by the change in resistance value.

[0078] In some embodiments, a control component is also included, which includes a resistance detection element 410 and a control unit 420; one end of the resistance detection element 410 is connected to the contact angle 430, and the other end is connected to the arc resistor 440, and the resistance detection element 410 feeds back data to the control unit 420 to determine the rotation angle through resistance changes.

[0079] Specifically, the resistance detection member 410 can be connected to the arc resistor 440 and the feeler 430 on both sides according to the above method, and the resistance value is obtained by the similar principle of the sliding rheostat, and the resistance value is fed back to the control unit 420, and the current angle is calculated by the control unit 420. Further, the angle can be coordinated with the amount of multi-nucleon transfer reactants detected by the subsequent equipment, or according to the needs of the experiment, and then the drive motor 220 can be controlled to adjust the angle. Preferably, the control unit 420 can be a feedback control computer.

[0080] The control component detects the test resistance value generated between the antenna 430 and the arc resistor 440 through the resistance detection element 410, and infers the current rotation angle, and feeds back to the control unit 420. The control unit 420 can control the rotation angle according to the current multi-nucleon transfer reactant collection situation to more efficiently collect and transmit the product to the next level equipment.

[0081] In some embodiments, in some implementations, the fixing chamber 310 and the deformation chamber 320 are welded together, a flange structure 500 is provided between the deformation chamber 320 and the collection chamber 330 , and the deformation chamber 320 and the collection chamber 330 are connected through the flange structure 500 .

[0082] By fixing and removing the flange, the collection chamber 330 can be changed to adapt to the size of the collection chamber 330 required by the next-level equipment of various experiments.

[0083] Furthermore, in some preferred embodiments, the deformation chamber 320 is a bellows.

[0084] Specifically, a high compression ratio welded bellows is used as a bending vacuum pipe, and a specific angle rotation of the pipe is achieved through a combination of a rotating bearing at the target axis position and an arc guide rail 250 with a fixed radius, and then a control system with a resistance scale and a servo motor as the main hardware is used to achieve precise angle rotation. Preferably, according to the transmission and emission angle of the beam, the selected bellows size can be 100mm inner diameter, 130mm outer diameter, and 110mm free length;

[0085] The collection chamber 330 is rotated by the compression, stretching and bending characteristics of the bellows, thereby collecting and transmitting multi-angles of multi-nucleon transfer reactants.

[0086] Furthermore, according to some embodiments of the present invention, the vacuum span problem of the accelerator during inflation of the physical experiment terminal can be effectively solved, and the air load problem caused by the inflation airflow effect of the differential system can be solved.
