Abstract

Considerable effort has been devoted to the development of superconducting undulators (SCUs) intended for particle accelerator-based light sources, including synchrotrons and free electron laser (FEL) facilities. Recently, a high-temperature superconducting (HTS) undulator prototype, consisting of staggered-array Re-Ba-Cu–O bulks, achieved an on-axis sinusoidal magnetic field profile with a peak amplitude B₀ of 2.1 T and a period length of 10 mm, resulting in a deflection parameter K = 1.96. Such a short period HTS undulator not only enables the generation of higher-energy photons, but also supports the construction of economically feasible and compact FELs with shorter linear accelerators (LINACs). This article provides a comprehensive review of recent advances in the staggered-array bulk HTS undulator as well as other types of HTS undulators. Furthermore, it offers insights into the development of engineering HTS undulator prototypes designed for deployment in synchrotron and free electron laser (FEL) facilities. We conclude by discussing opportunities for and the challenges facing the use of HTS undulators in practical applications.

高温超导波动体研究进展

用于粒子加速器光源的超导波动器（scu），包括同步加速器和自由电子激光（FEL）设备，已经投入了相当大的努力。最近，一个由Re-Ba-Cu-O错开阵列块体组成的高温超导（HTS）波动器原型，实现了峰值振幅B0为2.1 T、周期长度为10 mm的轴向正弦磁场剖面，其偏转参数K = 1.96。这种短周期的高温超导波动器不仅能够产生更高能量的光子，而且还支持用更短的线性加速器（LINACs）构建经济可行的紧凑的FELs。本文全面综述了交错阵列体高温超导波动器以及其他类型高温超导波动器的最新进展。此外，它还为设计用于同步加速器和自由电子激光（FEL）设施的工程HTS波动器原型的开发提供了见解。最后，我们讨论了在实际应用中使用高温超导波动器的机会和面临的挑战。
