Abstract

The invention provides a compact low-temperature and high-temperature superconducting hybrid solenoid magnet for a fusion reactor and a high-intensity magnetic field device. The compact low-temperature and high-temperature superconducting hybrid solenoid magnet is formed by stacking a plurality of low-temperature and high-temperature superconducting hybrid solenoid modules along the axial direction, wherein each hybrid solenoid module comprises a low-temperature superconducting winding, a high-temperature superconducting winding, a low-temperature superconducting winding outgoing line and a high-temperature superconducting winding outgoing line, the high-temperature superconducting winding is coaxially sleeved in the low-temperature superconducting winding, the low-temperature superconducting winding outgoing line and the high-temperature superconducting winding outgoing line are wound by clinging to the windings, the plurality of low-temperature and high-temperature superconducting hybrid solenoid modules are symmetrical about a median plane, for the modules above (or below) the median plane, the outgoing line of each module is controlled within a 90-degree azimuth angle, and during stacking, all the modules are stacked and assembled in the axial direction after rotating. According to the invention, the operation current and the use performance of the solenoid magnet are improved, the manufacturing and use cost is reduced, and the radial occupied space is small, so that the solenoid magnet is also suitable for some compact high-intensity magnetic fields and fusion reactors.
