Referring to fig. 1, 2 and 3 and 4, a hybrid solenoidal magnet according to an embodiment of the present invention is composed of eight layers of identical hybrid solenoidal magnet assemblies 1, the hybrid solenoidal magnet assemblies 1 comprising: the high-temperature superconducting winding 2, the high-temperature superconducting winding lower outgoing line 3, the high-temperature superconducting winding upper outgoing line 4, the low-temperature superconducting winding 5, the low-temperature superconducting winding lower outgoing line 6, the low-temperature superconducting winding upper outgoing line 7, the assembly gap 8 and the outgoing lines lead out arcs 9 and 10.

The high-temperature superconducting winding 2 is coaxially sleeved in the low-temperature superconducting winding 5, and an assembly gap 8 is formed between the low-temperature superconducting winding 5 and the high-temperature superconducting winding 2. In consideration of the winding errors of the high-temperature superconducting winding 2 and the low-temperature superconducting winding 5 in each hybrid solenoid magnet single assembly 1, an assembly gap 8 is reserved between the inner high-temperature superconducting winding and the outer low-temperature superconducting winding during design.
The leads at the two ends of the coil of the high-temperature superconducting winding 2 are respectively bent into an arc shape to form a lower outgoing line 3 of the high-temperature superconducting winding and an upper outgoing line 4 of the high-temperature superconducting winding. Wherein the lower outgoing line 3 of the high-temperature superconductive winding is positioned at the lower part of the high-temperature superconductive winding 2, and the upper outgoing line 4 of the high-temperature superconductive winding is positioned at the upper part of the high-temperature superconductive winding 2.
The leads at the two ends of the coil of the low-temperature superconducting winding 5 are respectively bent into an arc shape to form a lower outgoing line 6 of the low-temperature superconducting winding and an upper outgoing line 7 of the low-temperature superconducting winding. Wherein, the lower outgoing line 6 of the low-temperature superconducting winding is positioned at the lower part of the low-temperature superconducting winding 5, and the upper outgoing line 7 of the low-temperature superconducting winding is positioned at the upper part of the low-temperature superconducting winding 5.

For example, the lead wires extend up to a height above the superconducting windings. When in use, current is introduced into the magnet through the winding lead-out wire, and a magnetic field is generated.
Referring to fig. 1 and 2, the hybrid solenoid magnet according to the embodiment of the invention is symmetrical about a midplane 11, and more than the midplane 11 is formed by stacking four hybrid solenoid magnet single assemblies 1 rotated by 0 °, 90 °, 180 °, 270 ° in the axial direction, respectively.

Referring to fig. 2 and 4, the low-temperature and high-temperature superconductive hybrid solenoid magnet is formed by respectively winding a lower outgoing line 6 of the low-temperature superconductive winding and an upper outgoing line 7 of the low-temperature superconductive winding in close contact with the low-temperature superconductive winding 5. The lower outgoing line 3 of the high-temperature superconductive winding and the upper outgoing line 4 of the high-temperature superconductive winding are respectively wound tightly against the high-temperature superconductive winding 2. The high-temperature superconducting winding lower outgoing line 3, the high-temperature superconducting winding upper outgoing line 4, the low-temperature superconducting winding lower outgoing line 6 and the low-temperature superconducting winding upper outgoing line 7 are wound and led out through continuous two or more sections of arc-shaped leads which are tangential to the outgoing points and are close to the low-temperature and high-temperature superconducting mixed solenoid magnet, the radius of the leads of the outgoing lines outgoing arc 9 and 10 is close to the external radius or the internal radius of the magnet as much as possible, so that the outgoing lines are tightly wound out of the magnet, the occupation of the whole magnet in radial space can be reduced, and the bending radius of the outgoing lines is ensured to meet the minimum bending radius requirement of the conductor.
