Description

Technical Field

[0001] The present invention relates to the technical field of cyclotron accelerators, in particular to a stripping target head. Background Art

[0002] A cyclotron is a device that uses a combination of magnetic and electric fields to cause charged particles to perform cyclotron motion, repeatedly accelerating them through a high-frequency electric field during motion. When ions move in the magnetic field generated by an electromagnet, their trajectory describes a circle under the action of the Lorentz force. As the electrodes are accelerated by the alternating electric field, the radius of the ions' orbit expands, eventually leaving the cyclotron's magnetic field. The stripping membrane is a key module used by the cyclotron to strip off the extracted beam. However, the stripping membrane used in the cyclotron is extremely thin, typically ranging from tens to hundreds of nanometers in thickness, and is easily broken during installation and vacuuming.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0032] Reference below Figures 1 to 7 , describing a lift-off target head 100 according to an embodiment of the present invention.

[0033] like Figure 1 and Figure 2As shown, the stripping target head 100 of the embodiment of the present invention can be applied to a cyclotron stripping extraction device. The stripping target head 100 includes a mounting base 1 , a stripping film 2 , a wire 3 , a mounting tube 7 and a conductive column 10 .

[0034] The mounting base 1 has a first end 11, a second end 12, and a third end 13. The first end 11 is close to the cyclotron center of the ion beam, and the second end 12 is located at both ends of the cyclotron direction of the ion beam. The mounting base 1 is provided with an opening 14, which passes through the two second ends 12 and connects to the first end 11. The third end 13 is located on both sides of the cyclotron direction of the ion beam, and the two third ends 13 are provided with a wire groove 131. The stripping film 2 is coated on the first end 11 and the two second ends 12 and covers the opening 14. The wire 3 has a high melting point and contacts the stripping film 2. The two ends of the wire 3 are arranged in the wire groove 131 of the two third ends 13, and the two ends of the wire 3 are fixed to the mounting base 1 by fasteners. The mounting tube 7 is provided on the mounting base 1 and is connected to the ground wire. The conductive column 10 is provided on the mounting tube 7 and connected to the mounting base 1.

[0035] For easier understanding, refer to Figure 1 For explanation, the ion beam can be located at the front side of the mounting base 1 and make a rotating motion in the horizontal plane. The first end 11 can refer to the front end of the mounting base 1, the second end 12 can refer to the left and right ends of the mounting base 1, and the third end 13 can refer to the upper and lower ends of the mounting base 1.

[0036] The stripping film 2 can be a whole film that stops at the first end 11, and after being folded in half, one side covers the second end 12 on the left side, and the other side covers the second end 12 on the right side. The opening 14 allows the ion beam to pass through the stripping film 2, and because the opening 14 is provided on the second end 12, the opening 14 is open to the left and right sides and the front side (see Figure 1 ), so that the area around the second end 12 around the opening 14 can support the stripping film 2, improving the installation reliability of the stripping film 2 and ensuring current signal acquisition. The wire 3 abuts the front end of the stripping film 2, supporting and securing the stripping film 2. One end of the wire 3 is installed in the upper wire groove 131, and the other end is installed in the lower wire groove 131. Fasteners are then used to secure the ends of the wire 3 to the mounting base 1. The wire 3 is then tightened to secure it.

[0037] Because the release film 2 is an extremely thin film, it is wrapped around the first end 11 and the second end 12 of the mounting base 1 and supported and limited by the wire 3. This makes installation of the release film 2 relatively simple and prevents the release film 2 from being pressed during installation, thereby reducing the probability of the release film 2 being broken due to excessive force. The wire 3 has a high melting point to prevent the wire 3 from melting due to high temperatures, where a high melting point can refer to a melting point of above 2000 degrees Celsius.

[0038] It should be noted that the above-mentioned positions of the first end 11, the second end 12 and the third end 13 are only given as examples and are not intended to be specific limitations on the positions of the first end 11, the second end 12 and the third end 13. Depending on the specific situation, the first end 11, the second end 12 and the third end 13 may be located at other positions of the mounting base 1, which will not be detailed here.

[0039] The mounting tube 7 serves as a mounting support for assembling the stripping target head 100 with external devices or components. The conductive post 10 is provided on the mounting tube 7 and connected to the mounting base 1. The conductive post 10 can output the current signal collected by the stripping film 2. Since the mounting tube 7 is connected to the ground wire, the conductive post 10 can be protected from magnetic field interference. That is, the interference of the magnetic field on the current signal drawn out by the conductive post 10 is reduced, thereby facilitating the improvement of the accuracy of the current signal collected from the accelerator stripping film.

[0040] According to the stripping target head 100 of the embodiment of the present invention, the stripping film 2 covers the first end 11 and the two second ends 12 and covers the opening 14, which facilitates the beam to pass through the stripping film 2 and makes the installation of the stripping film 2 relatively simple. The wire 3 contacts the stripping film 2 and is set on the mounting seat 1 through fasteners, which can support and limit the stripping film 2, thereby improving the installation reliability of the stripping film 2 on the mounting seat 1. The installation structure of the stripping film 2 in the stripping target head 100 is simple, which can reduce the probability of the stripping film 2 being broken during installation, and at the same time reduce the interference of the magnetic field on the current signal induced by the conductive column 10, thereby facilitating the improvement of the accuracy of the current signal of the stripping film of the acquisition accelerator.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the mounting base 1 is provided with a first screw hole 15, and the fastener is a first threaded fastener 5, which is disposed within the first screw hole 15. In this technical solution, the first threaded fastener 5 is mounted on the mounting base 1 through the first screw hole 15, and each end of the wire 3 is wrapped around the first threaded fastener 5. By twisting the first threaded fastener 5, the wire 3 is tightened, thereby securing the wire 3 to the mounting base 1 and, in turn, securing the release film 2. This method of securing the wire 3 with the first threaded fastener 5 and the first screw hole 15 is relatively simple, secure, and convenient to operate.

[0042] Optionally, the first threaded fastener 5 includes but is not limited to a bolt, a stud, and a screw.

[0043] In some embodiments, such as Figure 1 and Figure 2As shown, the two second ends 12 are provided with positioning grooves 121, which are connected to the first end 11. The opening 14 is provided in the positioning grooves 121. The positioning grooves 121 have side groove surfaces 1211 adjacent to the wire groove 131, and the release film 2 abuts against the side groove surfaces 1211. In this technical solution, the positioning grooves 121 can play a role in positioning the release film 2 during installation, allowing the release film 2 to be quickly installed on the second ends 12. Moreover, the side groove surfaces 1211, by abutting against the release film 2, can also accurately position the release film 2, thereby improving the installation reliability of the release film 2.

[0044] refer to Figure 1 For example, the upper and lower groove surfaces of the positioning groove 121 are side groove surfaces 1211. When the peeling film 2 is installed, the upper and lower ends of the peeling film 2 stop against the two side groove surfaces 1211, thereby limiting the upper and lower positions of the peeling film 2.

[0045] In some embodiments, such as Figure 1 As shown, a first rounded corner 1212 is provided at one end of the positioning groove 121 away from the peeling film 2. The first rounded corner 1212 can reduce the probability of stress concentration on the positioning groove 121, and also facilitate the processing of the positioning groove 121, which is beneficial to improving the yield rate of the mounting seat 1.

[0046] In some embodiments, such as Figure 1 As shown, a second rounded corner 14a is provided at one end of the opening 14 away from the peeling film 2. The second rounded corner 14a can reduce the probability of stress concentration on the opening 14, and also facilitate the processing of the opening 14, which is beneficial to improving the yield rate of the mounting base 1.

[0047] In some embodiments, such as Figures 1 to 4 As shown, mounting base 1 includes base 16 and bracket 17. Base 16 is provided with a slot 161, and a second screw hole 162 is provided on base 16, communicating with slot 161. Second threaded fastener 6 is disposed within second screw hole 162. Bracket 17 is partially disposed within slot 161, abutting against second threaded fastener 6. First end 11, second end 12, and third end 13 are disposed on bracket 17.

[0048] Mounting base 1 utilizes a split-body design, with base 16 and bracket 17 manufactured separately and then assembled to form mounting base 1. This reduces the complexity of mold making for mounting base 1 and, consequently, the manufacturing difficulty of mounting base 1. First end 11, second end 12, and third end 13 are all located on bracket 17, allowing release film 2 and thread 3 to be mounted on bracket 17 first and then mounted on base 16, simplifying assembly of release film 2 and thread 3.

[0049] When the bracket 17 and the base 16 are assembled, part of the bracket 17 is plugged into the base 16, and then the second threaded fastener 6 passes through the second screw hole 162 and abuts against the bracket 17, thereby fixing the bracket 17 to the base 16. The bracket 17 and the base 16 adopt this installation and fixing method, the structure is relatively simple, and installation and disassembly are also relatively convenient.

[0050] In some embodiments, such as Figure 1 As shown, a reference hole 172 is provided on the bracket 17. Before the stripping target head 100 operates, the position of the stripping target head 100 needs to be calibrated so that the beam to be tested hits the stripping film 2. Therefore, the reference hole 172 facilitates the calibration of the position of the bracket 17 relative to the main unit in the cyclotron stripping extraction device.

[0051] In some embodiments, such as Figure 1 and Figure 5 As shown, the portion of the bracket 17 located within the slot 161 is provided with a tapered hole 171, and the second threaded fastener 6 has a tapered portion 61 that abuts against the tapered hole 171. In this technical solution, the tapered portion 61 of the second threaded fastener 6 cooperates with the tapered hole 171 on the bracket 17, allowing the second threaded fastener 6 to limit the bracket 17 in multiple directions, achieving a better fixing effect.

[0052] refer to Figure 5 The tapered portion 61 cooperates with the tapered hole 171 so that the second threaded fastener 6 can limit the bracket 17 in the up and down directions and the front and back directions, thereby improving the fastening effect of the bracket 17 on the base 16.

[0053] Optionally, the second threaded fastener 6 includes but is not limited to a bolt, a stud, and a screw.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the base 16 is provided with extensions 163 on both sides of the ion beam rotation direction, and the third end 13 extends along the first direction. In the first direction, the size of the part of the bracket 17 located outside the slot 161 is smaller than the size of the extension 163.

[0055] In this technical solution, in the first direction, the size of the extension portion 163 is larger than the size of the portion of the bracket 17 located outside the slot 161. In this way, during the assembly or movement of the stripping target head 100, the extension portion 163 can protect the bracket 17, preventing the bracket 17 from colliding with other components, reducing the probability of damage to the stripping film 2, improving the safety of the stripping film 2, and also helping to reduce the number of times the stripping film 2 is replaced, thereby increasing the service life of the stripping film 2.

[0056] For example, the "first direction" can be Figure 2In the front-to-back direction, when the peeling target head 100 moves forward, the extension portion 163 contacts the component or object in front, thereby preventing the front side of the bracket 17 from being bumped, thereby protecting the peeling film 2 on the bracket 17. Of course, this is just an example, and the first direction is not limited to the front-to-back direction. It can be set specifically according to the situation, and will not be detailed here.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, in the second direction, the extension 163 is larger than the bracket 17, and the second direction is perpendicular to the second end 12. In this way, the extension 163 can provide more directional protection for the bracket 17. When the side of the bracket 17 located at the second end 12 approaches other components or objects, the extension 163 can contact the object before the bracket 17, thereby protecting the bracket 17 and the release film 2.

[0058] For example, the second direction can be Figure 2 In the left and right directions, the size of the extension part 163 is larger than the size of the bracket 17, which can be understood as the width of the extension part 163 is larger than the width of the bracket 17. When objects approach the left and right sides of the bracket 17, the extension part 163 can protect the left and right sides of the bracket 17 and prevent the left and right sides of the peeling film 2 from colliding.

[0059] In some embodiments, a shielding layer is provided on the base 16. In this technical solution, the shielding layer can be used to reduce the interference of the magnetic field on the current signal of the base 16, thereby facilitating more reliable collection of the current signal of the stripping film 2. Optionally, the shielding layer can be made of polyimide and aluminum foil.

[0060] In some embodiments, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, the stripping target head 100 further includes a pipe joint 8 and an insulating connecting post 9. The pipe joint 8 is sleeved within the mounting tube 7 and is provided with a first hole 81 and a second hole 82. The first hole 81 and the second hole 82 extend through the pipe joint 8. The base 16 is provided with a third hole 164 and a fourth hole 165. The conductive post 10 extends through the second hole 82 and has one end disposed within the fourth hole 165. One end of the insulating connecting post 9 is disposed within the first hole 81, and the other end is disposed within the third hole 164.

[0061] In this technical solution, the mounting tube 7 is connected to the base 16 via the pipe joint 8 and the insulating connecting post 9. The insulating connecting post 9 is inserted into the first hole 81 of the pipe joint 8 and the third hole 164 of the base 16 to achieve the connection between the pipe joint 8 and the base 16. This connection method is relatively simple and convenient for installation and removal.

[0062] The conductive column 10 passes through the second hole 82 and one end is set in the fourth hole 165 to connect the conductive column 10 to the base 16. The base 16 and the bracket 17 are conductive parts, so that the current signal collected by the stripping film 2 can be output outward through the conductive column 10.

[0063] In some embodiments, such as Figure 1 、 Figure 2 and Figure 6 As shown, the base 16 is provided with a fourth screw hole 166, the insulating connecting column 9 is provided with an annular groove 9a, and a fourth threaded fastener 03 is disposed within the fourth screw hole 166. One end of the fourth threaded fastener 03 abuts within the annular groove 9a. In other words, the insulating connecting column 9 is secured to the base 16 through the cooperation of the fourth threaded fastener 03, the fourth screw hole 166, and the annular groove 9a.

[0064] In some embodiments, such as Figure 1 As shown, the mounting tube 7 is provided with a fifth hole 7a, the pipe joint 8 is provided with a sixth screw hole 8a, the fifth hole 7a is provided with a fifth threaded fastener 04, and the fifth threaded fastener 04 is matched with the sixth screw hole 8a. In this way, the pipe joint 8 and the mounting tube 7 are fixedly assembled.

[0065] Optionally, the number of insulating connecting columns 9 may be 3, 4, etc., which will not be described in detail here.

[0066] Optionally, the insulating connecting column 9 may include but is not limited to a ceramic column.

[0067] Optionally, the conductive pillar 10 includes but is not limited to an aluminum alloy piece.

[0068] Optionally, the shapes of the mounting tube 7 , the pipe joint 8 , the insulating connecting column 9 and the conductive column 10 include but are not limited to circular, rectangular and pentagonal.

[0069] In some embodiments, such as Figure 1 As shown, Figure 3 As shown, a mounting groove 7b is provided on the inner wall of the mounting tube 7, and the pipe joint 8 is sleeved in the mounting groove 7b. In this technical solution, the pipe joint 8 is fixedly mounted inside the mounting tube 7 through the mounting groove 7b, which is conducive to improving the installation reliability between the pipe joint 8 and the mounting tube 7.

[0070] In some embodiments, such as Figure 1 、 Figure 3 and Figure 7As shown, the stripping target head 100 further includes an insulating support member 01. The insulating support member 01 is disposed within the mounting tube 7 and is provided with a central through-hole 011 and an eccentric hole 012. The eccentric hole 012 is used for vacuuming. A third screw hole 013 is provided on the side of the insulating support member 01. The third screw hole 013 communicates with the central through-hole 011. The conductive post 10 is passed through the central through-hole 011. A third threaded fastener 02 is disposed within the third screw hole 013 and abuts against the conductive post 10.

[0071] Considering the generally long length of the conductive post 10, the provision of the insulating support member 01 can support the conductive post 10 and prevent one end of the conductive post 10 from breaking due to its own weight. The conductive post 10 is mounted on the insulating support member 01 by passing through the central through hole 011. It is fastened to the insulating support member 01 via the third screw hole 013 and the third threaded fastener 02 to prevent the insulating support member 01 and the conductive post 10 from separating.

[0072] During the installation of the insulating support 01 and the conductive column 10 in the mounting tube 7 , the eccentric hole 012 is used to extract the vacuum in the mounting tube 7 to avoid the presence of air inside the mounting tube 7 and ensure the vacuum requirement when the stripping target head 100 is working.

[0073] In some embodiments, such as Figure 3 As shown, the insulating connecting post 9 is provided with a through hole 91 for vacuuming. The through hole 91 penetrates the insulating connecting post 9 along the axial direction of the insulating connecting post 9. In this technical solution, the through hole 91 is provided on the insulating connecting post 9. The through hole 91 can be used to vacuum the first hole 81 and the third hole 164, thereby preventing air from remaining in the first hole 81 and the third hole 164 and ensuring the vacuum requirement during operation of the stripping target head 100.

[0074] In some embodiments, such as Figure 1 As shown, the wire 3 is a high melting point metal wire. The use of metal wire can ensure that the wire 3 has sufficient strength and is not easy to break. Optionally, the wire 3 can include but is not limited to tungsten wire, molybdenum wire, rhenium wire, etc.

[0075] In some embodiments, the wire groove 131 includes but is not limited to a V-shaped groove, a rectangular groove, and a semicircular groove.

[0076] The cyclotron stripping and extraction device according to an embodiment of the present invention includes the aforementioned stripping target head 100 .

[0077] The cyclotron stripping extraction device is used to extract the beam. Its linear position and rotational azimuth angle require adjustment to achieve beams of varying energies. The remaining components and operation of the cyclotron stripping extraction device are well known to those skilled in the art and will not be described in detail here.
