近年来，铁基高温超导四极磁体在重离子加速器中得到了广泛的应用。铁主导的四极磁体的场分析是基于加速器开发早期的正常导电（NC）四极磁体。有些结论至今仍在使用。然而，铁主导的高温超导四极磁体的磁场不能完全遵循这些结论。本研究分别建立了高温超导四极磁体模型和数控四极磁体模型。分析比较了两种磁体的谐波特性。根据比较，传统的铁为主的四极磁铁可以设计为最大的磁场梯度，高温超导四极磁铁，但是，应考虑与变化的磁场梯度。最后，针对磁场梯度的变化，设计了高温超导四极磁体。与以往的研究结果相比，该设计的现场质量得到了提高。提出了高温超导四极磁体的新设计。
In recent years, the iron-dominated high-temperature superconductor (HTS) quadrupole magnets are being developed for heavy ion accelerators. Field analyses for iron-dominated quadrupole magnets were based on the normal-conducting (NC) quadrupole magnet early in the development for accelerators. Some conclusions are still in use today. However, the magnetic field of iron-dominated HTS quadrupole magnets cannot fully follow these conclusions. This study established an HTS quadrupole magnet model and an NC quadrupole magnet model, respectively. The harmonic characteristics of two magnets were analyzed and compared. According to the comparison, the conventional iron-dominated quadrupole magnets can be designed for maximum field gradient; the HTS quadrupole magnet, however, should be considered with varying field gradient. Finally, the HTS quadrupole magnet was designed for the changing field gradient. The field quality of the design was improved comparing with the result of the previous study. The new design for the HTS quadrupole magnet has been suggested.
