Abstract

The invention relates to a superconducting magnet for measuring comprehensive physical properties in a low-temperature high-intensity magnetic field and a design method thereof, the superconducting magnet comprises four groups of coils, three groups of coils are main coils, one group of coils is compensation coils, and all the coils are nested together, coaxial and concentric. From inside to outside, the first two sets of coils are main coils, the third set of coils are compensation coils, and the fourth set of coils are main coils, namely the compensation coils are located on the inner side of the first set of main coils. In order to optimize and adjust the safety margin of the coils, each group of coils adopts different lead specifications to realize radial current density grading, that is, each group of coils comprises a plurality of sub-coils, and the current density grading mode is not only applied to the main coil, but also applied to the compensation coil. The invention provides a compensation coil radial current density grading optimization method based on a target field method, provides a compensation coil layering design rule, and is applied to the design of a superconducting magnet for low-temperature strong magnetic field comprehensive physical property measurement.
