英文摘要Thermomagnetic instabilities are widely observed in bulk superconductors and superconducting (SC) films in form of flux jumps and flux avalanches. Recent experiments demonstrate that the frequent flux jumps can also be observed in superconducting coils. These undesirable flux jumps have a significant impact on coils. However, it is much more difficult to simulate the flux jumps in superconducting coils than bulk superconductors because of the unacceptable number of elements for such complex structures with composite materials. In this paper, we develop a possible scheme to numerically simulate the flux jumps inside the superconducting coils with acceptable computation resources, which allows us to qualitatively study the main characteristics of the thermomagnetic instabilities. Furthermore, we explore the sensitivity of flux jumps inside the superconducting solenoid to various electromagnetic and thermal parameters as well as the ramp rate. Our scheme of numerical simulation may pave an appropriate way to further study the thermomagnetic instabilities inside the various superconducting coils with complex structures.
