Description

Technical Field

[0001] The invention relates to the technical field of capacitors, in particular to a high-precision ion trap and an assembling method of the ion trap. Background Art

[0002] As the core component in cold molecular ion experiments, the ion trap plays a vital role. It can not only capture ions efficiently, but also precisely manipulate and detect the captured ions. In the working process of cold molecular ions, the ion trap first uses the electric field or magnetic field to stably capture the ions generated by laser sputtering of the target or photoionization of the atoms in the atomic reactor in the trap. Subsequently, the captured ions are manipulated using precise electric field or magnetic field control technology, such as selective excitation, acceleration or deceleration, to achieve ion separation and enrichment. Finally, the ion trap detects the manipulated ions through high-precision detection technology to obtain key information such as their quality and quantity, providing strong data support for subsequent cold molecular ion research. Therefore, the performance and stability of the ion trap directly affect the resolution, sensitivity and accuracy of cold molecular ions.

[0003] During the assembly process of traditional ion traps, slight deviations between components or improper assembly may lead to uneven electric field distribution, which will not only affect the ion capture efficiency, but also introduce errors in the manipulation and detection of ions, thereby reducing the accuracy and sensitivity of cold molecular ions. In addition, traditional assembly methods often rely on manual operations, which make it difficult to achieve precise control of assembly accuracy. Even for experienced technicians, it is difficult to completely avoid slight errors in the assembly process. These errors will be magnified in the precise structure of the ion trap, thus affecting its overall performance and stability. Summary of the invention

[0015] Furthermore, during the assembly of the high-precision ion trap, electrostatic protection measures need to be taken, including the use of anti-static workbenches, anti-static gloves and anti-static clothing, as well as regular testing of the static electricity level in the work area to prevent electrostatic discharge from damaging the sensitive components of the ion trap.

The plug fastening bolt 12 is made of plastic material as a whole. This design not only reduces the weight of the entire ion trap, but also avoids the electric field interference that may be caused by metal materials. During the assembly process, the plug fastening bolt 12 passes through the corresponding hole position on the X-shaped frame 3 and is tightly attached to the outside of the plug 4.

This design not only improves the durability and reliability of the ion trap, but also provides a strong guarantee for its subsequent efficient capture, precise control and stable detection.

[0024] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 , Figure 4As shown; a blade positioning hole 13 is provided on the surface of the X-shaped frame 3, and a blade positioning rod 14 with one end extending to the inside of the blade positioning hole 13 is movably connected to the end of the blade 6. A circular hole is provided on the end of the blade 6, wherein the end of the blade positioning rod 14 close to the blade 6 is located on the inside of the circular hole, wherein the number and distribution positions of the blade positioning holes 13 and the blade positioning rod 14 are mutually adapted to the blade 6. As the core supporting structure of the high-precision ion trap, the X-shaped frame 3 is not only required to have sufficient strength and stability, but also needs to consider the precise connection and positioning with key components such as the blade 6. In order to achieve this goal, blade positioning holes 13 are specially provided on the surface of the X-shaped frame 3, and the number and distribution positions of these blade positioning holes 13 are mutually adapted to the blade 6, ensuring that each blade 6 can have a corresponding positioning hole, thereby realizing the precise installation and positioning of the blade 6 on the X-shaped frame 3.

A circular hole is also provided on the end of the blade 6, and the end of the blade positioning rod 14 close to the blade 6 is located on the inner side of the circular hole. During the assembly process, the blade 6 is first placed at a predetermined position on the X-shaped frame 3 so that the circular hole on the blade 6 is aligned with the blade positioning hole 13 on the X-shaped frame 3. Then, one end of the blade positioning rod 14 passes through the circular hole on the blade 6 and extends to the inner side of the blade positioning hole 13. On the inside, the blade positioning rod 14 is fixed in the blade positioning hole 13, thereby realizing a stable connection and precise positioning of the blade 6 on the X-shaped frame 3. This connection method is not only simple and reliable, but also can effectively prevent the blade 6 from loosening or displacement during operation, thereby ensuring the uniformity and stability of the electric field distribution. At the same time, since the number and distribution positions of the blade positioning holes 13 and the blade positioning rods 14 are adapted to the blade 6, it can be ensured that each blade 6 can be accurately installed and positioned, thereby improving the working efficiency and accuracy of the entire ion trap.

[0025] In a preferred embodiment, the present invention can be further configured as follows: Figure 3 , Figure 5As shown; threaded holes are provided at both ends of the blade 6, and a fastening screw 15 with one end penetrating and extending to the other side surface of the X-shaped frame 3 is threadedly connected to the threaded hole. A fastening hole is provided on the surface of the X-shaped frame 3, and the fastening screw 15 is located on the inner side of the fastening hole, wherein the outer side of the fastening screw 15 is threadedly connected to a fastening nut 16, and the blade 6 is connected to the surface of the X-shaped frame 3 through the fastening screw 15 and the fastening nut 16, wherein the surfaces of the opposite sides of the two X-shaped frames 3 are provided with elliptical positioning grooves 17 for fixing the blade 6, wherein the number and distribution arrangement of the elliptical positioning grooves 17 are mutually adapted to the blade 6 As a crucial component in the ion trap, the blade 6 has a direct impact on the electric field distribution and ion capture efficiency due to its stability and position accuracy. In order to achieve a stable connection and precise positioning of the blade 6 on the X-shaped frame 3, the following structure is specially designed: First, threaded holes are provided at both ends of the blade 6. The design of these threaded holes enables the blade 6 to be connected to the X-shaped frame 3 by threaded connection. Specifically, one end of the fastening screw 15 is designed to penetrate and extend to the other side surface of the X-shaped frame 3, and the other end of the fastening screw 15 is threadedly connected to the threaded hole at the end of the blade 6. In order to ensure the stability of the fastening screw 15 on the X-shaped frame 3, fastening holes corresponding to the fastening screw 15 are opened on the surface of the X-shaped frame 3. When the fastening screw 15 passes through the blade 6 and extends to the other side of the X-shaped frame 3, it will be located on the inner side of these fastening holes. At this time, the blade 6 can be firmly fixed by threading the fastening nut 16 on the outer side of the fastening screw 15. In addition, in order to further improve the stability and position accuracy of the blade 6 on the X-shaped frame 3, elliptical positioning grooves 17 are opened on the surfaces of the opposite sides of the two X-shaped frames 3. The number and distribution of these elliptical positioning grooves 17 are The arrangement of the cloth is adapted to the blade 6, which means that each blade 6 can be accommodated and positioned by one or more elliptical positioning grooves 17. When the blade 6 is placed on the X-shaped frame 3, its edge will be close to the side wall of the elliptical positioning groove 17, thereby realizing the initial positioning of the blade 6 on the X-shaped frame 3. Finally, by rotating the fastening nut 16, the fastening screw 15 is gradually tightened and close to the X-shaped frame 3 and the blade 6, thereby realizing the final fixation of the blade 6 on the X-shaped frame 3. This connection method not only ensures the stability and position accuracy of the blade 6, but also makes the structure of the entire ion trap more compact and firm.

[0026] In a preferred embodiment, the present invention can be further configured as follows: Figure 5 , Figure 6As shown; reserved holes 18 for assembling compensation electrodes are also provided on the surface of the X-shaped frame 3. The X-shaped frame 3 is made of polyetheretherketone plastic, and the blade 6 is made of oxygen-free copper plated with 24k gold. As the core supporting structure of the ion trap, the design of the X-shaped frame 3 not only requires sufficient strength and stability, but also needs to consider the assembly and connection requirements with key components such as the blade 6 and the compensation electrode. In order to achieve this goal, reserved holes 18 for assembling compensation electrodes are specially provided on the surface of the X-shaped frame 3. The positions and numbers of these reserved holes 18 are precisely designed according to the size and layout of the compensation electrodes to ensure that the compensation electrodes can be accurately installed on the X-shaped frame 3, thereby achieving precise adjustment and optimization of the electric field. In terms of material selection, the X-shaped frame 3 is made of polyetheretherketone PEEK plastic. Polyetheretherketone plastic is a high-performance thermoplastic plastic with excellent mechanical properties, chemical stability and thermal stability. This material selection not only makes the X-shaped frame 3 have sufficient strength and durability, but also can maintain stable performance under high temperature and harsh environments. In addition, polyetheretherketone plastic also has good insulation properties, which can effectively isolate the electric field, reduce electric field interference and noise, thereby improving the accuracy and stability of the ion trap. On the other hand, as a key component for applying the radio frequency electric field in the ion trap, the material selection of blade 6 is also crucial. In order to achieve efficient electric field distribution and ion capture, blade 6 is made of oxygen-free copper plated with 24k gold. Oxygen-free copper is a high-purity copper material with excellent electrical conductivity and thermal conductivity. By plating a layer of 24k gold on its surface, not only can the electrical conductivity of blade 6 be further improved, but also its oxidation resistance and corrosion resistance can be enhanced, thereby extending the service life of blade 6. During the assembly process, the compensation electrode will be accurately installed on the X-shaped frame 3 through the reserved hole 18, and together with the blade 6 and other components, it forms a complete ion trap structure. Since the material selection of the X-shaped frame 3 and the blade 6 has been carefully considered and optimized, the entire ion trap structure not only has excellent electric field distribution and ion capture efficiency, but also can maintain stable performance under high temperature and harsh environment.

[0027] A method for assembling a high-precision ion trap comprises the following steps: Step 1. Preparation and protection: Operate in a clean room to ensure a clean environment. Wear gloves and masks throughout the process to protect the operator and prevent contamination. Step 2, assembling the blade and the X-shaped frame: thread the fastening screw 15 into the threaded hole of the blade 6, pass the blade 6 through the fastening screw 15 through the fastening hole of the X-shaped frame 3, and snap it into the elliptical positioning groove 17, use the blade positioning rod 14 to pass through the round holes of the X-shaped frame 3 and the blade 6 to ensure that the blade is accurately positioned, and use the fastening nut 16 to preliminarily fix the blade 6; Step 3, blade alignment and fixation: According to the above steps, assemble the remaining three blades 6 in sequence, stack the two X-shaped frames 3 up and down, install another X-shaped frame 3 from top to bottom, and slightly adjust the four blades 6 so that they are respectively stuck in the four elliptical positioning grooves 17 of the X-shaped frame 3, observe and fine-tune the four blades 6 under an industrial microscope to align them, and after alignment, tighten the fastening nut 16 again to accurately limit and fix them; Step 4: Install and fine-tune the plugs: Insert the two plugs 4 into the plug positioning holes 11 on the two X-shaped frames 3, respectively, and use the plug fastening bolts 12 to perform preliminary tightening. Observe and fine-tune the plugs 4 under an industrial microscope, and then use the plug fastening bolts 12 to accurately tighten after confirming the alignment. Step 5: Overall assembly and testing: Use M2 bolts 10 to connect the assembled ion trap to the support seat 2, place it on the optical platform for testing, and tighten it after ensuring it is level. Place the entire ion trap on the base 1, and use the first bolt 9 to pass through the first fixing hole 8 and the connecting hole in sequence to achieve center alignment and precise limit fixation.

[0028] The method emphasizes the cleanliness of the operating environment and the protective measures of the operator in step one, which is very important. During the assembly process of the ion trap, tiny dust or pollution may have an adverse effect on the performance of the ion trap and even cause the failure of the experiment. Therefore, the operation is carried out in a clean room and gloves and masks are worn throughout the process, which can minimize pollution, protect the health of the operator, and ensure the assembly quality of the ion trap. Secondly, in steps two and three, the method describes in detail the assembly process of the blade 6 and the X-shaped frame 3, as well as the alignment and fixing method of the blade 6. The blade 6 is firmly connected to the X-shaped frame 3 by using the fastening screw 15 and the fastening nut 16, and the accurate positioning of the blade is ensured by using the elliptical positioning groove 17 and the blade positioning rod 14, which can greatly improve the assembly accuracy and stability of the ion trap. In addition, observing and fine-tuning the four blades 6 under an industrial microscope to align them can further ensure the uniformity of the electric field distribution of the ion trap, thereby improving The efficiency of ion capture and manipulation. Again, step four describes in detail the installation and fine-tuning process of the plug 4. The plug is an important component in the ion trap, used to pass light and extract ions. By ensuring the accurate installation and alignment of the plug, the electric field interference and noise can be minimized, and the accuracy and stability of the ion trap can be improved. At the same time, the plug fastening bolts 12 are used for preliminary and precise tightening to ensure the stability of the plug and prevent it from loosening or falling off during the experiment. Finally, in step five, the method describes the overall assembly and testing process of the ion trap. By connecting the assembled ion trap to the support seat 2 with M2 bolts 10 and placing it on an optical platform to test its horizontality, the stability and accuracy of the ion trap can be ensured. At the same time, the entire set of ion traps is placed on the base 1, and the first bolts 9 are passed through the first fixing hole 8 and the connecting hole in sequence to achieve centering alignment and precise limit fixation, which can further improve the assembly accuracy and stability of the ion trap.

[0029] In a preferred embodiment, the present invention can be further configured as follows: Figure 8As shown; in step 2, avoid scratching the blade 6 during operation, and use alcohol to rinse it. When adjusting the blade, use your hands or plastic tweezers to avoid scratches caused by metal tools. The tightening process needs to be done slowly and with appropriate force to avoid damage to the blade or X-frame. In step 4, a fixed distance must be maintained between the plug 4 and the positioning rod of the blade 6 to prevent contact conduction. The fine-tuning process needs to be careful to ensure that the plug 4 is installed accurately. In step 5, silver-plated terminal blocks are used for wiring to prevent assembly errors caused by excessive force during wiring. When adjusting the position, it needs to be done according to the experimental requirements to ensure the accuracy of the ion trap. After the overall assembly is completed, necessary tests need to be performed to ensure the accuracy of the ion trap. The performance meets the requirements. In step 2, in order to avoid scratches on the blade 6 during operation, a series of preventive measures need to be taken. The blade is a key component in the ion trap, and the integrity of its surface is crucial to the performance of the ion trap. Therefore, before assembly, the blade can be rinsed with alcohol to remove stains and impurities on the surface and reduce the generation of scratches. When adjusting the blade, metal tools should be avoided as much as possible, because metal tools may leave scratches or damage on the blade surface. Instead, non-metal tools such as hands or plastic tweezers can be used to operate to reduce damage to the blade. In addition, when tightening the blade, it is necessary to operate slowly and with appropriate force. Avoid unnecessary damage to the blade or X-frame. Secondly, in step 4, you need to pay attention to the spacing between the plug 4 and the positioning rod of the blade 6. The plug is another key component in the ion trap, and its installation position and accuracy are equally important to the performance of the ion trap. In order to ensure that the plug and the blade do not contact and conduct, it is necessary to maintain a fixed spacing between them. In the process of fine-tuning the plug, you need to operate carefully to ensure that the plug is installed accurately and does not contact the blade or other components. In addition, you also need to pay attention to the tightness of the plug's fastening bolts to ensure the stability of the plug. Finally, in step 5, you need to pay attention to the details of wiring. Wiring is the assembly of the ion trap. An important link in the process, its quality directly affects the performance and stability of the ion trap. In order to ensure the accuracy and reliability of the wiring, silver-plated terminal blocks can be used for wiring. Silver-plated terminal blocks have good conductivity and corrosion resistance, which can ensure the stability and reliability of the wiring. When wiring, it is necessary to avoid excessive force to avoid assembly errors. In addition, the orientation of the ion trap needs to be adjusted according to experimental requirements to ensure its accuracy. After the overall assembly is completed, necessary tests are required to verify whether the performance of the ion trap meets the requirements. The tests include electric field application and ion loading efficiency tests in a vacuum to ensure that the performance of the ion trap meets the expected goals.

[0030] In a preferred embodiment, the present invention can be further configured as follows: Figure 8As shown; in the process of assembling a high-precision ion trap, the temperature and humidity of the assembly environment must be strictly controlled to ensure that the temperature of the assembly environment remains between 15°C and 25°C, and the humidity remains at a low humidity level, with a relative humidity not exceeding 40%. In the process of assembling a high-precision ion trap, the temperature and humidity control of the assembly environment is also crucial. Changes in temperature and humidity may have a significant impact on the assembly quality and performance of the ion trap, so they must be strictly controlled. First of all, regarding temperature control, it is necessary to ensure that the temperature of the assembly environment remains between 15°C and 25°C. This temperature range is based on a comprehensive consideration of many factors such as the thermal expansion coefficient of the ion trap material, the operating temperature range of the electronic components, and the comfort of the experimental operators. Too high or too low a temperature may cause thermal expansion or contraction of the ion trap material, thereby affecting its dimensional accuracy and stability. In addition, temperature changes may also affect the performance of electronic components, such as changes in parameters such as resistance and capacitance, thereby affecting the circuit performance and electric field distribution of the ion trap. Therefore, during the assembly process, it is necessary to use Constant temperature equipment or air conditioning system is used to maintain a stable temperature environment. Secondly, regarding humidity control, it is necessary to ensure that the humidity of the assembly environment is maintained at a low humidity level, and the relative humidity does not exceed 40%. Excessive humidity may cause the ion trap material surface to absorb moisture and form a water film or water droplets, which will not only affect the surface quality of the material, but may also introduce additional electric field interference and affect the performance of the ion trap. In addition, excessive humidity may also accelerate the corrosion and aging process of the material and shorten the service life of the ion trap. Therefore, during the assembly process, dehumidification equipment or desiccant is required to reduce the humidity level in the environment. In order to ensure that the temperature and humidity of the assembly environment are effectively controlled, the following measures need to be taken: Regularly monitor and record the temperature and humidity data of the assembly environment to promptly detect and deal with abnormal conditions. Before assembly, thoroughly clean and dry the assembly area to remove potential sources of pollution and moisture. During the assembly process, minimize the number of people entering and leaving the assembly area to reduce fluctuations in temperature and humidity. Use assembly equipment and tools with good sealing to prevent interference from the external environment.

[0031] In a preferred embodiment, the present invention can be further configured as follows: Figure 8As shown in the figure, during the assembly of high-precision ion traps, electrostatic protection measures need to be taken, including the use of anti-static workbenches, anti-static gloves and anti-static clothing, as well as regular testing of the static level in the work area to prevent electrostatic discharge from damaging the sensitive components of the ion trap. During the assembly of high-precision ion traps, electrostatic protection is a key link to ensure the stability of ion trap performance and avoid damage to sensitive components. Electrostatic discharge (ESD) may cause irreversible damage to the precision electronic components, optical components and micromechanical structures of the ion trap, so strict electrostatic protection measures must be taken. First of all, regarding the use of anti-static workbenches, this is a basic requirement for assembling high-precision ion traps. The anti-static workbench uses a grounding system to promptly conduct the static charge on the surface of the workbench to the earth, thereby avoiding static electricity accumulation. When selecting an anti-static workbench, it is necessary to ensure that its surface resistance meets the relevant standards and has sufficient load-bearing capacity and stability to meet the operational requirements during the assembly process. Secondly, anti-static gloves and anti-static clothing are also essential electrostatic protection measures. These equipment can effectively prevent the static charge generated by the human body from damaging the sensitive components of the ion trap. Anti-static gloves are usually made of insulating materials and have good insulation and wear resistance. , can ensure the safety during the operation, anti-static clothing can cover the whole body of the operator to prevent the static charge generated by the friction of clothing from threatening the ion trap. In addition to using anti-static workbenches, anti-static gloves and anti-static clothing, regular detection of the static level in the working area is also an important means to ensure the effectiveness of electrostatic protection measures. By using electrostatic detection instruments, the static level in the working area can be monitored in real time, and potential static threats can be discovered and dealt with in a timely manner. During the detection process, it is necessary to ensure the accuracy and reliability of the detection instrument, and to calibrate and maintain the detection instrument regularly to ensure its long-term stable operation. In addition, in order to ensure the effectiveness of electrostatic protection measures, the following measures need to be taken: During the assembly process, minimize unnecessary personnel entering and exiting the work area to reduce the introduction and spread of static charge. Before assembly, train and guide operators on electrostatic protection knowledge to improve their electrostatic protection awareness and operating skills. Use anti-static materials and tools for assembly, such as anti-static mats, anti-static packaging bags, etc., to reduce the possibility of electrostatic discharge. Regularly clean and maintain anti-static workbenches, anti-static gloves and anti-static clothing to ensure that their surface resistance and conductivity meet the requirements.
