Description

Technical Field

[0001] The present invention relates to the technical field of position monitoring, and in particular to a collimation measurement reference network device and method, which are suitable for rapid installation and debugging and positioning of particle accelerator components. Background Art

[0002] Alignment technology refers to the measurement technology for accurately measuring the position of accelerator components. It is the premise and basis for installing accelerator components to the theoretical design position with high precision. At present, the alignment and positioning technology of accelerator components in the world is mainly based on laser tracker technology. First, in the pre-alignment process, the magnetic center line and magnetic center plane of the accelerator magnet component are converted into the position of the alignment target. Then, during the installation of the accelerator, the position of the alignment target is measured with a laser tracker, and the position and posture of the magnet component are adjusted according to the measurement data. The measurement accuracy of this technology can reach 30 microns, which is mainly limited by the accuracy of the laser tracker itself. In the alignment measurement process, the actual accuracy may be worse due to the influence of environmental changes and the error accumulation process of segmented alignment measurement over a long distance. In order to improve the alignment accuracy of magnet components, the BNL laboratory in the United States has developed a vibration line measurement technology. By measuring the electromagnetic induction signal of the vibration line, the relative position of the magnet on a magnet bracket can be accurately measured with an accuracy of 30 microns. A simple estimate, assuming that the error amplification factor of the storage ring is more than 100 times, means that under the existing collimation accuracy, the beam orbit distortion can reach 3 mm, which may not only exceed the dynamic aperture of the diffraction-limited storage ring, but will also inevitably cause a significant deterioration of the dynamic aperture and momentum aperture, making it difficult to store the beam. It is necessary to develop first-loop correction technology based on electron beams and high-precision magnet mechanical support technology that supports online precision adjustment to overcome this difficulty. Therefore, the development of higher-precision collimation measurement technology is the first choice to solve the influence of tolerances, which can effectively reduce the difficulty of first-loop beam debugging and better control engineering and technical risks. Accurate measurement of the position and attitude of accelerator magnets depends on the comprehensive application of various technologies. First of all, it is necessary to be able to transfer the center plane and center line of the magnet to an external "visible" reference - a coordinate target seat or a reference plane or a reference line with high precision. Secondly, in small-scale installation spaces (several meters), that is, in the local measurement station area, the application of advanced instruments or measurement techniques can accurately measure the position and attitude of the magnet reference; finally, for large accelerator devices, all components are required to be accurately positioned in the global coordinate system, which requires high-precision linking of the reference network during transfer station measurements. Summary of the invention

At this time, L1 serves as the baseline of the entire combined system. The tensioning wire meter A-tensioning wire meter A on the left and right substrates simultaneously uses L1 as the measurement target, and records the four measurement values ​​of the two tensioning wire meters A as the basis for restoring the virtual baseline during future on-site installation. At the same time, the two electronic inclinometers on the two substrates work, and record the four readings after the adjustment as the basis for restoring the posture of the two substrates during future on-site measurements; after the pre-alignment is completed, enter the on-site installation, first of all, the installation of the linear accelerator part, the straight part of the transport line, and the straight section of the storage ring; in the linear accelerator part, the straight part of the transport line, and the straight section of the storage ring: the pre-aligned table support and magnet are transported as a whole to the machine installation site, and initially positioned by a laser tracker; the tensioning wire baseline L2 is established through the secondary network points. In order to meet large-scale installation, it is necessary to consider the overlap of the tensioning wires, and in the overlapped part There is a second reference line L3 appearing at the same time, and the overlapped part can also improve the accuracy of alignment measurement; adjust the posture of the table support according to the four readings of the two electronic inclinometers during pre-alignment; according to the readings of the tensioning line instrument A-tensioning line instrument A during pre-alignment, calculate the position of the reference line L1 at the tensioning line instrument B-tensioning line instrument B through the relationship conversion between the coordinate systems established by each sensor; adjust the table support position so that the reading of L2 at the tensioning line instrument B-tensioning line instrument B conforms to the position data obtained by reverse calculation; check the readings of the two NIVELs, fine-tune the posture of the sensor, and conform to the readings during pre-alignment, and the on-site installation of the straight part is completed; install at least four reasonably distributed and adapted 1.5-inch ceramic ball target seats on the upper end surface of the secondary iron, and the coordinate system used in magnetic measurement and the component coordinate system should be unified. The coordinate system parameters are determined by measuring the characteristic structural parameters of the magnet by a three-coordinate measuring machine. The coordinates of the outer 1.5-inch ceramic ball target seat are obtained by the three-coordinate measuring machine in this unified coordinate system and are retained and archived as the permanent technical parameters of the magnet. .

[0006] The present invention also provides a collimation measurement reference network method, comprising the following steps:

[0007] First, the single substrate 16 is calibrated, and the tensioning wire meter A40, the static level 41, the electronic inclinometer 42, and the tensioning wire meter B43 are unified in the substrate 16 coordinate system; then, the substrate 16 is fixedly mounted on both ends of the upper panel of the table A7 of each magnet 1 assembly, and the long side of the substrate 16 is made perpendicular to the beam direction, and the offline pre-alignment is started;

[0008] Secondly, the pre-alignment adopts the vibration line alignment method, that is, a metal wire L1 with a diameter of about 0.5 mm is passed through the center of the magnet 1 to be measured, and the vibration parameters of the energized wire in the magnetic field are measured. By adjusting the position of the magnet 1, the magnetic center of each magnet 1 is made to coincide with the wire L1. At this time, L1 is used as the reference line of the entire combined system. The tensioning wire meter A40-tensioning wire meter A40 on the left and right substrates 16 simultaneously uses L1 as the measurement target, and records the four measurement values ​​of the two tensioning wire meters A as the basis for restoring the virtual reference line during future on-site installation. At the same time, the two electronic inclinometers 42 on the two substrates 16 work and record the four readings after the adjustment is completed, which are used as the basis for restoring the posture of the two substrates 16 during future on-site measurements.

[0009] Again, after the pre-alignment is completed, we will enter the on-site installation, starting with the installation of the linear accelerator part, the straight section of the transport line, and the straight section of the storage ring.

[0010] Furthermore, the specific steps for installing the linear accelerator part, the transport line straight section, and the storage ring straight section are as follows:

[0011] The first step is to transport the pre-aligned table support 6 and magnet 1 as a whole to the machine installation site and place them in place using a laser tracker;

[0012] The second step is to establish the tension line reference line L2 through the secondary network points. In order to meet the needs of large-scale installation, the overlap of the tension line needs to be considered. A second reference line L3 will appear at the overlap part. At the same time, the overlap part can also improve the accuracy of the collimation measurement.

[0013] The third step is to adjust the posture of the table support 6 according to the four readings of the two electronic inclinometers 42 during pre-alignment;

[0014] The fourth step is to calculate the position of the reference line L1 at the tensioning line meter B43-tensioning line meter B43 according to the reading of the tensioning line meter A40-tensioning line meter A40 during pre-alignment through the relationship conversion between the coordinate systems established by various sensors; adjust the position of the table support 6 so that the reading of L2 at the tensioning line meter B43-tensioning line meter B43 conforms to the position data obtained by inverse calculation;

[0015] In the fifth step, check the readings of the two NIVELs and fine-tune the sensor's attitude to match the readings during pre-alignment. This completes the on-site installation of the straight section.

[0016] Furthermore, at least four reasonably distributed and adapted 1.5-inch ceramic ball target seats 44 are installed on the upper end surface of the secondary iron. The coordinate system and component coordinate system used in magnetic measurement should be unified. The coordinate system parameters are determined by measuring the characteristic structural parameters of the magnet using a three-coordinate measuring machine. The coordinates of the outer 1.5-inch ceramic ball target seat 44 are obtained by the three-coordinate measuring machine in the unified coordinate system and retained and archived as permanent technical parameters of the magnet 1.

[0017] The principle of the present invention is that the measurement reference network device of the present invention is to reasonably distribute the tensioning wire instrument 5, the static level 41, and the electronic inclinometer 42 on the indium steel substrate 16 to establish a combination of multiple reasonably superimposed measurement systems. The reference line of the tensioning wire instrument 5 measurement system is used as the linear reference to perform high-precision alignment adjustment on each component; at the same time, the static level can provide high-precision data in the vertical direction for comparison and compensation; the tensioning wire instrument and the static level are on the same substrate, and the inclination of the substrate will have a great impact on the measurement results, so an electronic inclinometer is needed to monitor the inclination.

[0018] The beneficial effects of the present invention are:

[0019] (1) The present invention combines the advantages of different high-precision sensors to achieve global control measurement of key components under a common platform and coordinate system, and improves the alignment installation accuracy to a relative position accuracy better than 20 microns within a 100-meter sliding window.

[0029] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a collimation measurement reference network device of the present application includes a magnet 1, an M30X100 bolt 2, an M30 nut 3, a magnet height adjustment mechanism 4, a tensioning wire instrument 5, a table support 6, a table A7, an M12X40 hexagon socket screw 8, a spring washer A9, a short adjustment seat 10, an adjustment seat 11, an M8X50 hexagon socket screw 12, an M8X30 hexagon socket screw 13, a spring washer B14, a T-shaped adjustment seat 15, a base plate 16, a rectangular hollow bracket 17, a tensioning wire instrument conversion seat 18, and a static level base 19, electronic inclinometer fixing seat 20, electronic inclinometer base A21, electronic inclinometer base B22, plate 23, support plate A24, support plate B25, pressure block 26, M6X35 hexagon socket screw 27, table B28, M12X60 bolt 29, V-shaped frame 30, M6X30 hexagon socket bolt 31, wire pressing V-shaped frame 32, 1.5-inch ceramic ball 33, tension wheel hanging plate 34, M6X20 hexagon socket bolt 35, tension wheel shaft 36, tension wheel 37, deep groove ball bearing 38, M16 nut 39. Table A7 is welded on the top of the table support 6; the magnet height adjustment mechanism 4, short adjustment seat 10, adjustment seat 11, T-shaped adjustment seat 15 and base plate 16 are connected to the table A7 by bolts;

[0031] like Figure 5 As shown, firstly, the single substrate 16 is calibrated, and the tensioning wire meter A40, the static level 41, the electronic inclinometer 42, and the tensioning wire meter B43 are unified in the coordinate system of the substrate 16. Then, the substrate 16 is fixedly mounted on both ends of the upper panel of the table A7 of each magnet 1 assembly, and the long side of the substrate 16 is perpendicular to the beam direction, and the offline pre-alignment is started.

[0032] like Figure 5As shown, the pre-alignment adopts the vibration line alignment method, that is, a metal wire L1 with a diameter of about 0.5 mm is passed through the center of the magnet 1 to be tested, and the vibration parameters of the energized wire in the magnetic field are measured. By adjusting the position of the magnet 1, the magnetic center of each magnet 1 coincides with the wire L1. At this time, L1 serves as the reference line of the entire combined system. The tensioning wire meter A40-tensioning wire meter A40 on the left and right substrates 16 simultaneously uses L1 as the measurement target, and records the four measurement values ​​of the two tensioning wire meters A as the basis for restoring the virtual reference line during future on-site installation. At the same time, the two electronic inclinometers 42 on the two substrates 16 work and record the four readings after the adjustment is completed, which serves as the basis for restoring the posture of the two substrates 16 during future on-site measurements. Multi-pole magnets such as four-pole and six-pole magnets can be pre-aligned using the vibration line method. When designing and processing the magnet, no less than four 1.5-inch ceramic ball target seats 44 should be fixedly installed on the periphery of the magnet 1, especially on the upper end surface. The coordinate system used in magnetic measurement is consistent with the component coordinate system of magnet 1. The establishment method is: find and fix the characteristic structure of magnet 1, place magnet 1 on a three-coordinate machine to measure its characteristic structure (the ball center measurement accuracy and point position measurement accuracy of the three-coordinate machine are 2 microns), establish the component coordinate system, and then measure the coordinate value of the 1.5-inch ceramic ball target seat 44 on the periphery of magnet 1 (especially the upper end face), which will be used as the permanent geometric calibration value of the magnet 1, one-to-one correspondence with the identity code of the magnet 1 and archived. When measuring the magnetic field of magnet 1, the nominal magnetic field position or deviation value should be based on the coordinates in the above-mentioned component coordinate system. According to the design theoretical value and the actual position of the magnetic center obtained by pre-alignment, the three-dimensional coordinate value of each 1.5-inch ceramic ball target seat 44 in each magnet 1 component coordinate system is calculated, which will be used for the initial positioning of the laser tracker during on-site installation, as well as the calculation data for installation using the chord distance ruler.

[0033] like Figure 6As shown, after the pre-alignment is completed, the on-site installation begins. The first step is to install the linear accelerator part, the straight part of the transport line, and the straight section of the storage ring. The first step is to transport the pre-aligned table support 6 and the magnet 1 as a whole to the machine installation site and initially position them through the laser tracker; the second step is to establish the tension line reference line L2 through the secondary network points. In order to meet large-scale installation, it is necessary to consider the overlap of the tension line. A second reference line L3 will appear at the overlap part at the same time. At the same time, the overlap part can also improve the alignment measurement accuracy. The third step is to adjust the posture of the table support 6 according to the four readings of the two electronic inclinometers 42 during pre-alignment; the fourth step is to calculate the position of the reference line L1 at the tensioning line meter B43-tensioning line meter B43 (the overlapping part also includes the tensioning line meter C45-tensioning line meter C45) (reflected by the reading of the tensioning line meter) according to the reading of the tensioning line meter A40-tensioning line meter A40 during pre-alignment; the position of the table support 6 is adjusted (note: the upper adjustable part of the table support 6 is adjusted as a whole) so that the reading of L2 (L3) at the tensioning line meter B43-tensioning line meter B43 (tensioning line meter C45-tensioning line meter C45) is consistent with the position data obtained by inverse calculation; the fifth step is to check the readings of the two NIVELs, fine-tune the posture of the sensor to match the readings during pre-alignment, and the on-site installation of the straight part is completed.

[0034] like Figure 7As shown, the bending part of the physical structure of the particle accelerator must be accompanied by the appearance of a secondary magnet. Since the secondary magnet is not convenient to find the magnetic center by the vibration line pre-alignment method, the magnetic measurement system needs to be measured on a special magnetic measurement machine to determine the relative relationship parameters between the magnetic center (line) and the alignment reference (target) outside the magnet. In order to complete the installation of all equipment using the alignment reference network technology, we install at least four reasonably distributed and adapted 1.5-inch ceramic ball target seats 44 on the upper end face of the secondary iron. Just like the method of establishing the coordinate system in the multi-pole magnet pre-alignment process, the coordinate system used in magnetic measurement and the component coordinate system should be unified. The coordinate system parameters are determined by measuring the characteristic structural parameters of the magnet through a three-coordinate machine. The coordinates of the outer 1.5-inch ceramic ball target seat 44 are obtained by the three-coordinate measuring machine in this unified coordinate system and are retained and archived as the permanent technical parameters of the magnet 1. The specific installation steps are as follows: the first step is to pre-align the secondary magnet: an alignment reference network substrate 16 is installed at both ends of the upper end surface of the secondary iron support 6, and the longitudinal central axis angle of the substrate 16 is equal to the bending angle of the magnet (at this time, the central axis is also perpendicular to the magnetic center line at both ends of the secondary magnet); the component coordinate system of the secondary magnet is established according to the reference benchmark of the magnetic measurement device; during the magnetic measurement process, a strict geometric relationship between the magnetic center and the 1.5-inch ceramic ball target seat 44 on the periphery of the magnet is established, and the three-dimensional coordinates of these 1.5-inch ceramic ball target seats 44 are determined in the component coordinate system; at the same time, the geometric relationship between the magnetic center and the eight 1.5-inch ceramic balls 33 on the two substrates 16 is fixed in the component coordinate system to determine their coordinate values; note that at this time, the two electronic inclinometers 42 are working normally, and the pre-alignment is recorded. At the end of alignment, their readings are taken so as to restore the posture of the magnet during on-site installation. The second step is to transport the magnet and its support as a whole to the site during on-site installation, use a laser tracker for initial positioning, and check the coordinate position of the 1.5-inch ceramic ball 33 on the substrate 16 (the component coordinate system can be converted into the machine coordinate system at this time), with a point position accuracy better than 0.05 mm; at the same time, adjust the posture of the magnet 1 according to the reading of the electronic inclinometer 42; the third step is to use the alignment reference network to finely adjust the position of the secondary iron: the two substrates 16 at both ends of the secondary iron correspond to the two adjacent and intersecting alignment network benchmarks, and according to the coordinate conversion, the theoretical distance from the center of the 1.5-inch ceramic ball target seat 44 on the outer periphery of the magnet to the two reference lines L2 and L3 under ideal conditions can be calculated. Use a high-precision chord distance ruler to measure the vertical distance from the four (or more) 1.5-inch ceramic ball target seats 44 on the upper end face of the magnet to the two reference lines L2 and L3, adjust the upper adjustable part of the support 6 until these distance values ​​reach the calculated values, and check the reading of the electronic inclinometer 42 at the same time. After meeting the original reading requirements, lock and fix the final position. At this point, the secondary iron on-site installation is completed.

[0035] After the particle accelerator is installed, it is necessary to conduct continuous, long-term and regular deformation monitoring and analysis of the particle accelerator. Traditional deformation monitoring means mainly include laser trackers, total stations, levels, inclinometers and other measurement methods. In the present invention, due to the establishment of a high-precision alignment reference network, long-term continuous deformation monitoring can be achieved, that is, under the premise of ensuring that the reference point of the network remains unchanged, the tensioning wire meter A40, static level 41, electronic inclinometer 42, tensioning wire meter B43, and tensioning wire meter C45 on the substrate 16 in the network can monitor position changes in multiple directions, and their readings can be uploaded to the computer in real time (very short period) and analyzed. Among them, the tensioning wire gauge A40, the tensioning wire gauge B43, and the tensioning wire gauge C45 can monitor the position change of the magnet support 6 in the two lateral directions (the change may come from the deformation of the support 6 structure, ground settlement, etc.), the static level 41 can monitor the change of the magnet support 6 in the vertical direction (the change may come from the deformation of the support 6, the ground settlement at the corresponding position, etc.), and the electronic inclinometer 42 can monitor the tilt change in two directions on the horizontal plane. During the machine maintenance stage, photogrammetry can be used to perform regular deformation detection and measurement, and the accuracy and reliability of the results of the reference network monitoring can also be reviewed and checked. The specific method is: obtain the 1.5-inch ceramic ball 33 on the upper end face of each magnet 1 and the reference straight line L2 of the tensioning line instrument B43 at the corresponding position (part of the overlap includes two reference lines L2 and L3), solve the vertical distance from the center of the 1.5-inch ceramic ball 33 to the reference straight lines L2 and L3 on the line target of the center of the 1.5-inch ceramic ball 33, and check whether they have changed and the amount of change compared with the theoretical value or the previous measurement value, so as to achieve the purpose of monitoring the position change of the magnet. At the same time, as the basis for the analysis of long-term changes, the DPA digital photogrammetry system is used to measure the position relationship of each magnet 1 relative to the tensioning lines L2 and L3 in turn, and the data of each observation cycle are returned to the initial state, that is, the first measurement value after installation is used as the initial state observation value, and then the deformation value of each cycle relative to the initial cycle is calculated according to the least squares principle. These data are of great significance for the later machine operation, adjustment, and deformation prediction analysis.

A method for collimating measurement reference network, using the collimating measurement reference network device according to claim 1, characterized in that: The steps include: First, a single substrate (16) is calibrated, and the tensioning wire meter A (40), the static level (41), the electronic inclinometer (42), and the tensioning wire meter B (43) are unified in the substrate (16) coordinate system; then, the substrate (16) is fixedly mounted on both ends of the upper panel of the table A (7) of each magnet (1), and the long side of the substrate (16) is made perpendicular to the beam direction, and offline pre-alignment is started; Secondly, the pre-alignment adopts the vibration line alignment method, that is, a metal wire L1 with a diameter of about 0.5 mm is passed through the center of the magnet (1) to be measured, and the vibration parameters of the metal wire L1 in the magnetic field are measured. By adjusting the position of the magnet (1), the magnetic center of each magnet (1) is made to coincide with the metal wire L1. At this time, the metal wire L1 is used as the baseline of the alignment measurement reference network device. The tensioning wire meter A (40)-tensioning wire meter A (40) on the left and right substrates (16) simultaneously uses the metal wire L1 as the measurement target, and records the four measurement values ​​of the two tensioning wire meters A as a basis for restoring the virtual baseline during future on-site installation. At the same time, the two electronic inclinometers (42) on the two substrates (16) work and record the four readings after the adjustment is completed as a basis for restoring the posture of the two substrates (16) during future on-site measurement. Once again, after the pre-alignment is completed, we will now enter the on-site installation, starting with the installation of the linear accelerator section, the linear section of the transport line, and the linear section of the storage ring; The specific steps for installing the linear accelerator part, the linear part of the transport line, and the linear section of the storage ring are as follows: The first step is to transport the pre-aligned table support (6) and the magnet (1) as a whole to the machine installation site and place them in place using a laser tracker; The second step is to establish the tension line reference line L2 through the secondary network points. In order to meet the needs of large-scale installation, the overlap of the tension line needs to be considered. A second reference line L3 will appear at the overlap part, and the overlap part can also improve the accuracy of the collimation measurement. The third step is to adjust the posture of the table support (6) according to the four readings of the two electronic inclinometers (42) during pre-alignment; The fourth step is to calculate the position of the reference line L1 at the tensioning line instrument B (43)-tensioning line instrument B (43) based on the reading of the tensioning line instrument A (40)-tensioning line instrument A (40) during pre-alignment by converting the relationship between the coordinate systems established by the tensioning line instrument A (40), the static level (41), the electronic inclinometer (42), and the tensioning line instrument B (43); and adjust the position of the table support (6) so that the reading of the tensioning line reference line L2 at the tensioning line instrument B (43)-tensioning line instrument B (43) conforms to the position data obtained by inverse calculation; The fifth step is to check the readings of the two NIVELs and fine-tune the postures of the tensioning wire gauges A (40) and B (43) to match the readings during pre-alignment. The on-site installation of the straight section is completed.

The coordinate system used in magnetic measurement and the component coordinate system should be established in a unified manner.

The establishment method is: finding and fixing the characteristic structure of the magnet (1), placing the magnet (1) on a three-coordinate measuring machine to measure its characteristic structure, establishing the component coordinate system, and determining the coordinate system parameters by measuring the characteristic structure parameters of the magnet (1) by the three-coordinate measuring machine. The coordinates of the peripheral 1.5-inch ceramic ball target seat (44) are obtained by the three-coordinate measuring machine in the unified coordinate system and are retained and archived as permanent technical parameters of the magnet (1).
