| 英文摘要 | a homogeneous magnetic field superconducting magnet with a cold bore of 250 mm and a central field of 4.3 t has been designed, manufactured, and tested with zero liquid helium boil-off. as a result of magnetic field homogeneity considerations, the magnet is composed of three coaxial coils: one main coil and two compensation coils. all coils are connected in series and can be charged with a single power supply. the magnetic field homogeneity is about ±3.0 % from −200 mm to 200 mm in axial direction with 86 mm in diameter. the magnet can be operated in persistent mode with a superconducting switch. a two-stage gm cryocooler with a capacity of 1.5 w at 4.2 k was used to cool the superconducting magnet. the cryocooler prevents the liquid helium from boiling off and leads to zero helium loss during static operation. the magnet can be operated in liquid helium circumstance by cooling the gas helium with the cryocooler without additional supply of liquid helium. under this condition, the magnet is successfully operated up to 4 t without quench. the magnet system can be generating 0.25 l/h liquid helium with the cryocooler by supplying the gas helium without loading the magnet. in this paper, the magnet design, manufacture, mechanical behavior analysis, and the performance test results of the magnet are presented. |
