[0002] The High Intensity heavy-ion Accelerator Facility (HIAF) is an advanced heavy-ion research facility that integrates a high-intensity superconducting linear accelerator, a heavy-ion synchrotron and a storage ring. It combines the high pulse current of a linear accelerator and the high energy of a synchrotron, and uses the most advanced technologies in the world, such as high-intensity ion source, superconducting linear acceleration, beam accumulation and beam cooling. Its goal is to build a next-generation high-intensity heavy-ion accelerator with international leading level, capable of producing nuclides extremely far from the stable line, and can provide the world's highest peak current low-energy heavy ion beam, the highest energy pulsed heavy ion beam of 4.25 GeV / u, and the world's highest nuclear mass measurement spectrometer. It provides internationally leading experimental research conditions for identifying new nuclides, expanding the nuclide map, studying bound nuclear structures and reaction mechanisms, and especially accurately measuring the mass of short-lived nuclei far from the stable line.

The accelerator system includes a high-current superconducting ion source (SECR), a superconducting ion linear accelerator (iLinac), a multifunctional enhancer (BRing), a high-precision multifunctional experimental storage ring (SRing), and a radioactive beam line (HFRS) connecting Bring and SRing. The HFRS section of the HIAF magnet system is composed of a superconducting magnet and a room-temperature magnet. Except for several radiation-resistant magnetic elements at the front end of the pre-separator, the remaining dipole and multipole magnets in the HFRS are superconducting magnets. It is mainly composed of 11 superconducting dipole magnets and 13 superconducting multipole combination magnets.

[0034] like Figure 4 As shown, the superconducting multi-pole magnet docking tooling 2 includes a V-groove support assembly 21, an axial fine-tuning assembly 22, and an axial rotation tooling 23; the V-groove support assembly 21 is composed of a V-groove body 211 and a support bearing. The support bearing can be set as a roller bearing 212.

[0035] The roller bearings 212 are installed in pairs on both sides of the V-shaped groove 211 and are exposed at an appropriate distance from the V-shaped edge, ensuring that when the superconducting multipolar magnet 4 or the connecting structure 5 is placed on the superconducting multipolar magnet docking tooling 2, the outer surface of the roller bearing 212 is in contact; the axial fine-tuning assembly 22 is composed of an angle adjustment block 221 and an adjustment bolt assembly 222. The angle adjustment block 221 is symmetrically fixed on the lateral end surfaces of the V-shaped groove 211, and the adjustment bolt assembly 222 is connected to the axial fine-tuning assembly 222 through the threaded holes on the V-shaped groove 211.

The upper retaining ring 231 is placed on the upper part of the superconducting multipole magnet 4, and the lower retaining ring 233 has an extension block at the ±60° position and is placed in the middle of the groove gap of the V-groove support assembly 21. The upper retaining ring 231 and the lower retaining ring 233 are connected by the fastener 232 and clamped on the outer surface of the superconducting multipole magnet 4.

[0036] like Figure 5 and Figure 6As shown, the center axis lead-out tool 3 includes a centering positioning wheel 31 and a center axis 32; the centering positioning wheel 31 is installed in the inner cavity of the superconducting multipole magnet 4, and the center axis 32 passes through the centering positioning wheel 31 and leads out of the superconducting multipole magnet 4 to facilitate the measurement of the laser tracker; the centering positioning wheel 31 is composed of a large ring 311, a large ring adjustment screw 312, a rigid member 313, a small ring 314 and a small ring adjustment screw 315; the large ring 311 and the small ring 314 are connected by a circumferentially uniformly distributed rigid member 313, and the large ring is used to adjust the The screw 312 is pressed against the inner cavity wall of the superconducting multipole magnet 4 to be adjusted in the four directions of up, down, left and right, so that the large ring 311 meets the concentricity requirement with the inner cavity of the superconducting multipole magnet 4; the small ring adjusting screw 315 is used to apply force on the central axis 32 to adjust in the four directions of up, down, left and right, so that the concentricity deviation between the central axis 32 and the inner cavity of the superconducting multipole magnet 4 is minimized; the central axis 32 is processed with lightweight and high rigidity materials, with an overall straightness of ≤0.05, and the straightness and concentricity of the finely processed sections at both ends are both ≤0.01.

[0037] like Figure 7 As shown, the superconducting multipole combination magnet includes three superconducting multipole magnets 4 arranged with overlapping central axes and target points 44. Two connecting structures 5 are respectively arranged between two adjacent superconducting multipole magnets. Multiple groups of target points 44 are respectively fixed in the upper half of the superconducting multipole magnet 4 near the two ends.

[0038] like Figures 1 to 7 As shown, after the central axis lead-out tooling 3 and the superconducting multipole magnet 4 are installed, the inner cavity of the superconducting multipole magnet 4 is used as a reference, and points (about 40-60 points) are taken at four sections of the inner cavity using a measuring target ball, and four circles are measured to fit the actual axis of the magnet; the central axis lead-out tooling 3 is used to align the end face of each superconducting multipole magnet 4 one by one (machine tool drawing lines) to determine its circumferential angle position, and the central axis 32 is adjusted to be concentric with the superconducting multipole magnet 4 using a laser tracking instrument. Then, after the superconducting multipole combination magnet and the superconducting multipole magnet docking tool 2 are hoisted onto the machine tool as a whole, the micrometer is used to adjust the axis of the superconducting multipole combination magnet to be parallel to the main shaft feed of the machine tool, and the laser tracker is used for re-measurement to measure the angle between the end face of the superconducting multipole magnet 4 and the axis of the central axis 32, providing input conditions for end face repair, and after the superconducting multipole combination magnet is adjusted to the deviation range according to the re-measurement data, the end face is finely processed to make the end face have excellent flatness and good verticality with the axis of the central axis 32; all the data after the final correction of the magnet measurement is completed are led to the target point 44 set on the upper side of the cylinder of each superconducting multipole magnet 4. In conjunction with the laser tracker, the double-layer three-dimensional adjustable bracket 1 is adjusted to a horizontal position through the three-dimensional adjustment base 11, and the elevation difference of the entire bracket does not exceed 0.2mm. The elevation of the four sets of longitudinal tracks 14 on the basic frame 12 is measured, and the elevation difference of the track surface does not exceed 0.1mm.

[0039] First, the middle superconducting multipole magnet 4 and the superconducting multipole magnet docking tooling 2 matched therewith are installed on the upper three-dimensional adjustment support seat assembly 15, and a coordinate system is established with a double-layer three-dimensional adjustable bracket 1. After restoring the position of the target point 44 and the center axis on the superconducting multipole magnet 4, the superconducting multipole magnet 4 is leveled through the upper three-dimensional adjustment support seat assembly 15, and compared with the absolute coordinates, x (horizontal direction) and y (vertical direction) are adjusted to 0.

[0040] Then, the superconducting multipole magnets 4 arranged at both ends and the superconducting multipole magnet docking tooling 2 matched therewith are respectively installed on the upper three-dimensional adjustment support seat assembly 15, and the relative coordinate system of the superconducting multipole magnet 4 in the middle is used as the reference for adjustment. After that, the two connection structures 5 are respectively fixed on the two end surfaces of the superconducting multipole magnet 4 in the middle, and then the limiting assembly 151 is used to push the superconducting multipole magnets 4 at both ends close to the other connection surface of the connection structure 5. After the connection surfaces are in contact, the laser tracker is used to align the positions of the superconducting multipole magnets 4 at both ends. If the measured data is within the deviation range, it can be locked with bolts. During the locking process, the laser tracker monitors the three superconducting multipole magnets 4 in real time.

[0041] If the measured data is outside the deviation range, the superconducting multipole magnets 4 at both ends are aligned respectively using the upper three-dimensional adjustment support seat assembly 15 and the connecting hole frame. After alignment, they are locked with bolts. During the locking process, the laser tracker monitors the three superconducting multipole magnets 4 in real time. Finally, the superconducting multipole combination magnet is re-measured as a whole. If the re-measured data meets the requirements, the assembly of the superconducting multipole combination magnet is completed.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
