In the HFRS section of the HIAF magnet system, superconducting magnets are combined with normal-temperature magnets. Except for a few radiation-resistant magnetic elements at the front end of the pre-separator, all the dipole and multipole magnets in the HFRS are superconducting magnets. The main components of the HFRS are 11 superconducting dipole magnets and 13 superconducting multipole combined magnets. The main features of these superconducting magnets are large aperture, long integral length, high magnetic rigidity, high main quadrupole field gradient, and high integral field uniformity.

[0042] As shown in Figure 4 , the superconducting multi-pole magnet docking tool 2 includes a V-shaped groove support assembly 21, an axial fine adjustment assembly 22, and an axial rotation tool 23. The V-shaped groove support assembly 21 is composed of a V-shaped groove body 211 and a support bearing. The support bearing can be a roller bearing 212.

[0043] The roller bearings 212 are installed in pairs on both sides of the V-shaped groove body 211 and are exposed at a proper distance from the V-shaped edge, so that when the superconducting multi-pole magnet 4 or the connecting structure 5 is placed on the superconducting multi-pole magnet docking tool 2, it contacts the outer surface of the roller bearing 212. The axial fine adjustment 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 horizontal two end surfaces of the V-shaped groove body 211. The adjustment bolt assembly 222 is matched with the axial rotation tool 23 through the threaded hole on the V-shaped groove body 211, and the axial high-precision adjustment of the superconducting multi-pole magnet 4 to ±20° is completed.

The upper clasp ring 231 and the lower clasp ring 233 are connected by the fastener 232 and are clamped on the outer surface of the superconducting multi-pole magnet 4.

[0044] As shown in Figure 5 and Figure 6As shown, the center axis leading 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 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 adjusting screw 312, a rigid member 313, a small ring 314 and a small ring adjusting screw 315; the large ring 311 and the small ring 314 are connected by the circumferentially distributed rigid members 313, the large ring adjusting screw 312 is used to tightly press against the inner cavity wall of the superconducting multipole magnet 4 to adjust in the up, down, left and right four directions, 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 center axis 32 to adjust in the up, down, left and right four directions, so that the concentricity deviation of the center axis 32 with the inner cavity of the superconducting multipole magnet 4 reaches the minimum; the center axis 32 is processed by using lightweight and high-rigidity material, and the overall straightness is ≤0.05, and the straightness and concentricity of the two end finishing sections are both ≤0.01.

[0045] As shown in Figure 7 , the superconducting multipole assembly magnet includes three superconducting multipole magnets 4 arranged with coincident center axes and target points 44. Two connecting structures 5 are arranged between adjacent two superconducting multipole magnets respectively. Multiple groups of target points 44 are fixed in the upper half of the superconducting multipole magnet 4 near the regions close to the two ends.

[0046] As shown in Figures 1 to 7 , after the center axis leading tool 3 is installed with the superconducting multipole magnet 4, the inner cavity of the superconducting multipole magnet 4 is used as a reference to take points (about 40-60) in four sections of the inner cavity using measuring target balls to measure four circles and fit the actual axis of the magnet; the center axis leading tool 3 is used to align each end face of the superconducting multipole magnet 4 one by one to determine the angular position thereof, and the laser tracker is used to adjust the center axis 32 and the superconducting multipole magnet 4 to be concentric. Then, after the superconducting multipole assembly magnet and the superconducting multipole magnet butt joint tool 2 are hoisted as a whole onto the machine tool, the axis of the superconducting multipole assembly magnet is adjusted to be parallel to the feed of the main shaft of the machine tool using a micrometer, the laser tracker is used for re-measurement to measure the included angle between the end face of the superconducting multipole magnet 4 and the axis of the center axis 32, to provide input conditions for end face rework, and after the superconducting multipole assembly magnet is adjusted to be within the deviation range according to the re-measurement data, the end face is finished to have excellent flatness and perpendicularity with the axis of the center axis 32; all data measured after the final corrected magnet is measured are introduced to the target points 44 arranged on the upper side of the cylinder of each superconducting multipole magnet 4. The double-layer three-dimensional adjustable support 1 is adjusted to a horizontal position by three-dimensional adjustment base 11 in cooperation with the laser tracker, the elevation difference of the entire support is not more than 0.2mm, and the elevations of the four groups of longitudinal rails 14 on the base frame 12 are measured, and the elevation difference of the rail surfaces is not more than 0.1mm.

[0047] First, the intermediate superconducting multipole magnet 4 and the superconducting multipole magnet butt joint tool 2 matched therewith are installed on the upper three-dimensional adjusting support seat assembly 15 to establish a coordinate system with the double-layer three-dimensional adjustable support 1, and after the target point 44 on the superconducting multipole magnet 4 and the central axis position are restored, the superconducting multipole magnet 4 is leveled by the upper three-dimensional adjusting support seat assembly 15, and compared with the absolute coordinate, the x (horizontal transverse direction) and y (vertical direction) are adjusted to 0 point.

[0048] Subsequently, the superconducting multipole magnets 4 arranged at both ends and the superconducting multipole magnet butt joint tools 2 matched therewith are installed on the upper three-dimensional adjusting support seat assembly 15, and are adjusted based on the relative coordinate system of the intermediate superconducting multipole magnet 4. Then, the two connecting structures 5 are fixed on the two end faces of the intermediate superconducting multipole magnet 4, and the two end superconducting multipole magnets 4 are pushed to the other connecting faces of the connecting structures 5 by the limiting assembly 151. After the connecting faces are contacted, the position of the two end superconducting multipole magnets 4 is collimated by the laser tracker, and when the measurement data is within the deviation range, the superconducting multipole magnets 4 are locked by bolts. During the locking process, the laser tracker monitors the three superconducting multipole magnets 4 in real time.

[0049] If the measurement data is outside the deviation range, the two end superconducting multipole magnets 4 are collimated by the upper three-dimensional adjusting support seat assembly 15 and the connecting hole frame, and after collimation, the superconducting multipole magnets 4 are locked by bolts. During the locking process, the laser tracker monitors the three superconducting multipole magnets 4 in real time. Finally, the superconducting multipole combined magnet is re-measured, and when the re-measurement data meets the requirements, the assembly of the superconducting multipole combined magnet is completed.
