Description

Collimation measurement reference network device and method

Technical Field

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

Background

The collimation technique is a measurement technique for accurately measuring the position of an accelerator member, and is a premise and a basis for mounting the accelerator member to a theoretical design position with high accuracy. At present, the alignment positioning technology of the international accelerator component is mainly based on the laser tracker technology. Firstly, in the pre-collimation process, the magnetic center line and the magnetic center plane of the accelerator magnet component are converted into the position of the collimation target. Then, during the accelerator mounting process, the position of the alignment target is measured by the laser tracker, and the position and attitude of the magnet member are adjusted based on the measurement data. The measurement precision of the technology can reach 30 microns, and is mainly limited by the precision of the laser tracker. In the collimation measurement process, the actual accuracy may be worse due to the influence of the change of the environment and the influence of the error accumulation process of the segmented collimation measurement in a long distance. In order to improve the alignment accuracy of the magnet components, the international U.S. BNL laboratory develops a vibration line measurement technology, which measures the electromagnetic induction signal of the vibration line to accurately measure the relative position of the magnets on a magnet support, and the accuracy can reach 30 microns. Simple estimation, assuming that the error amplification factor of the storage ring is more than 100 times, means that the beam orbit distortion can reach 3 mm under the existing collimation precision, which not only may exceed the dynamic aperture of the diffraction limit storage ring, but also will cause obvious deterioration of the dynamic aperture and momentum aperture, and the beam is difficult to store. It is necessary to develop a first-turn electron beam-based correction technique and a high-precision magnet mechanical support technique supporting on-line fine adjustment to overcome this difficulty. Therefore, a higher-precision collimation measurement technology is developed, the influence of tolerance is solved, the difficulty of debugging the first-circle beam can be effectively reduced, and the engineering technical risk can be better controlled. The accurate measurement of the position and the posture of the accelerator magnet depends on the comprehensive application of various technologies. First, the center plane and centerline of the magnet must be able to be transferred with high precision to an external "visible" reference, either a coordinate backing plate or a reference plane or a reference straight line. Secondly, in a small-scale installation space (several meters), namely a local measuring station area, the position and the posture of the magnet reference can be accurately measured by applying an advanced instrument or a measuring technology; finally, for large accelerator devices, accurate positioning of all elements in the global coordinate system is required, which requires high-precision linking of reference networks during the measurement at the transfer station.

A table A7 is welded above the table support 6; the bench A7 is connected with a magnet height-adjusting mechanism 4, a short adjusting seat 10, an adjusting seat 11, a T-shaped adjusting seat 15 and a base plate 16 through bolts;

as shown in fig. 5, the single substrate 16 is first calibrated, and the tensiometer a40, the static level 41, the electronic inclinometer 42, and the tensiometer B43 are unified under the coordinate system of the substrate 16. Then, the base plates 16 are respectively and fixedly installed at the two ends of the upper plate of the table a7 of each magnet 1 assembly, the long sides of the base plates 16 are perpendicular to the beam direction, and off-line pre-collimation is started.

As shown in fig. 5, the pre-collimation adopts a vibration line collimation method, i.e. a metal wire L1 with a diameter of about 0.5 mm passes through the center of the magnet 1 to be measured, the vibration parameters of the energized wire in the magnetic field are measured, and the magnetic center of each magnet 1 is coincided with the wire L1 by adjusting the position of the magnet 1. At this time, L1 is taken as a reference line for the entire combined system. The tensiometer A40-the tensiometer A40 on the left and right base plates 16 simultaneously takes L1 as a measurement target, and records four measurement values of the two tensiometers A as a basis for recovering a virtual reference line in future field installation. And simultaneously, the two electronic clinometers 42 on the two substrates 16 work, and four readings after the adjustment is finished are recorded and used as the basis for recovering the postures of the two substrates 16 in the future field measurement. The multi-pole magnets such as the four-pole and six-pole magnets can be pre-aligned by using the vibration line method. At the time of designing and processing the magnet, not less than four 1.5-inch ceramic ball target seats 44 are fixedly arranged on the periphery, particularly the upper end face, of the magnet 1. The coordinate system used in magnetic measurement is consistent with the element coordinate system of the magnet 1, and the establishment method comprises the following steps: searching and fixing the characteristic structure of the magnet 1, placing the magnet 1 on a three-coordinate machine to measure the characteristic structure (the ball center measurement precision and the point position measurement precision of the three-coordinate machine are 2 microns), establishing an element coordinate system, then measuring the coordinate value of a 1.5-inch ceramic ball target seat 44 on the periphery (particularly the upper end face) of the magnet 1, and using the coordinate value as a permanent geometric calibration value of the magnet 1, corresponding to the identity code of the magnet 1 one by one and saving the permanent geometric calibration value. When the magnet 1 is used for magnetic field measurement, the nominal magnetic field position or deviation value should be based on the coordinates in the above-mentioned element coordinate system. And calculating three-dimensional coordinate values of each 1.5-inch ceramic ball target seat 44 under each magnet 1 element coordinate system according to the design theoretical value and the actual magnetic center position obtained by pre-collimation, and using calculation data of initial positioning of a laser tracker during field installation and chord length scale installation.

After the pre-collimation is complete, the installation now proceeds to the field, first of all the installation of the linac section, the transport line straight section, the storage ring straight section, as shown in fig. 6. Firstly, integrally transporting the pre-aligned table support 6 and the magnet 1 to a machine installation site, and preliminarily positioning the table support and the magnet by a laser tracker; and secondly, establishing a pilot line reference line L2 through secondary mesh points, considering the overlapping of the pilot lines in order to meet large-scale installation, wherein a second reference line L3 can appear at the overlapping part at the same time, and the alignment measurement precision can be improved by the overlapping part. Thirdly, adjusting the posture of the table support 6 according to the four readings of the two electronic inclinometers 42 during pre-collimation; fourthly, according to the reading of the tensiometer A40-the tensiometer A40 during pre-collimation, calculating the position (reflected by the reading of the tensiometer) of the datum line L1 on the tensiometer B43-the tensiometer B43 (the lap joint part also comprises the tensiometer C45-the tensiometer C45) through the relation conversion between coordinate systems established by all sensors; adjusting the position of the table support 6 (note: adjusting the upper adjustable part of the table support 6 as a whole) to make the reading of L2(L3) in the tensiometer B43-tensiometer B43 (tensiometer C45-tensiometer C45) conform to the position data obtained by inverse calculation; and fifthly, checking the readings of the two NIVELs, finely adjusting the postures of the sensors, conforming to the readings during pre-collimation, and finishing the field installation of the linear parts.

As shown in fig. 7, the bent portion of the physical structure of the particle accelerator is accompanied by the occurrence of the secondary magnet, and since the secondary magnet is not convenient for finding the magnetic center by the pre-alignment method of the vibration line, the magnetic measurement system is required to perform magnetic measurement on a special magnetic measuring machine and determine the relative relationship parameter between the magnetic center (line) and the alignment reference (target) outside the magnet. In order to complete the installation of all the devices by using the collimation reference network technology, at least four ceramic ball target seats 44 which are reasonably distributed and matched with 1.5 inches are arranged on the upper end surface of the secondary iron. Like the method for establishing the coordinate system of the pre-alignment process of the multi-pole magnet, the coordinate system used in magnetic measurement and the coordinate system of the element should be established uniformly, the parameters of the coordinate system are determined by measuring the characteristic structure parameters of the magnet through a three-coordinate measuring machine, and the coordinates of the peripheral 1.5-inch ceramic ball target holder 44 are obtained by the three-coordinate measuring machine under the uniform coordinate system and are reserved and filed as the permanent technical parameters of the magnet 1. The specific installation steps are as follows, the first step, the pre-collimation of the secondary magnet: the two ends of the upper end face of the secondary iron support 6 are provided with collimation reference network substrates 16, and the included angle of the longitudinal central axis of the substrate 16 is equal to the bending angle of the magnet (at the moment, the central axis is also just vertical to the magnetic central line at the two ends of the secondary magnet); establishing an element coordinate system of the secondary magnet according to the reference datum of the magnetic measurement device; establishing a strict geometric relationship between the magnetic center and the 1.5-inch ceramic ball target seats 44 at the periphery of the magnet in the magnetic measurement process, and determining the three-dimensional coordinates of the 1.5-inch ceramic ball target seats 44 in an element coordinate system; fixing the geometrical relationship between the magnetic center and the eight 1.5-inch ceramic balls 33 on the two substrates 16 in the element coordinate system at the same time, and determining the coordinate values thereof; note that at this point the two electronic inclinometers 42 are operating properly, recording their readings at the end of pre-collimation, to restore the attitude of the magnets during field installation; secondly, during field installation, the magnet and the support are integrally transported to the field, a laser tracker is used for initial positioning, the coordinate position of the 1.5-inch ceramic ball 33 on the substrate 16 is checked (at this time, an element coordinate system can be converted into a machine large coordinate system), and the point position precision is better than 0.05 mm; meanwhile, the posture of the magnet 1 is adjusted according to the reading of the electronic clinometer 42; thirdly, fine adjustment of the position of the secondary iron is carried out by using a collimation reference network: the two base plates 16 at the two ends of the secondary iron respectively correspond to two adjacent crossed collimation network references, and the theoretical distance from the center of the 1.5-inch ceramic ball target seat 44 at the periphery of the magnet to the two reference lines L2 and L3 in an ideal state can be calculated according to coordinate conversion. The vertical distances from four (or more) 1.5-inch ceramic ball target seats 44 on the upper end face of the magnet to two reference lines L2 and L3 are measured by using a high-precision chord distance ruler, the adjustable parts on the upper layer of the support 6 are adjusted until the distance values reach calculated values, and meanwhile, the reading of the electronic inclinometer 42 is checked, and the final position is locked and fixed after the original reading requirement is met. And finishing the field installation of the secondary iron.

After the particle accelerator is installed, the particle accelerator needs to be continuously monitored and analyzed for long term and periodically, and the traditional deformation monitoring means mainly comprises a laser tracker, a total station, a level gauge, an inclinometer and other measuring methods. Among them, the tensiometer a40, the tensiometer B43 and the tensiometer C45 can monitor the position change of the magnet support 6 in two directions transversely (the change may come from the deformation of the support 6 structure, the ground settlement and the like), 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 of the corresponding position and the like), and the electronic inclinometer 42 can monitor the inclination change in two directions in the horizontal plane. In the machine maintenance stage, a photogrammetry means can be used for carrying out regular deformation detection measurement, and meanwhile, the precision and the reliability of the result of the reference network monitoring can be rechecked and checked. The specific method is as follows: photogrammetry is carried out to obtain a 1.5-inch ceramic ball 33 on the upper end face of each magnet 1 and a reference straight line L2 (a part of an overlapping part comprises two reference lines L2 and L3) of a tensiometer B43 at a corresponding position, the vertical distance from the center of the 1.5-inch ceramic ball 33 to a line target of the reference straight line L2 and L3 on the equal-height surface of the center of the 1.5-inch ceramic ball 33 is calculated, and whether the line target changes and changes with a theoretical value or a previous measured value is checked, so that the purpose of monitoring the position change of the magnet is achieved. Meanwhile, as an analysis basis of long-term change, a DPA digital photogrammetry system is adopted to sequentially measure and obtain the position relation of each magnet 1 relative to the tensile lines L2 and L3, data of each observation period are reduced to an initial state, namely, a first measurement value after installation is used as an initial state observation value, and then a deformation value of each period relative to the initial period is calculated according to the least square principle. The data has important significance for machine operation, adjustment and deformation forecast analysis in the later period.
