提出了一种短周期混合型交错波荡器。钒永磁(VP)磁极和NdFeB磁体的适当组合可提供比传统交错波动器大约40%的峰值场强。周期为15 mm的混合型交错波荡器在间隙为6 mm时，峰值场强超过0.8T。在液氮温度(77K)下，用镝作磁极，用PrFeB作磁体，在相同的带隙下可以获得更高的峰值磁场(∼0.94T)。
A short-period hybrid-type staggered undulator is proposed. A proper combination of vanadium Permendur (VP) pole and NdFeB magnet provide approximately 40% larger peak field strength than a conventional staggered undulator. The peak field of a 15-mm-period hybrid staggered undulator exceeds 0.8 T at a gap of 6 mm. Also, by using dysprosium as a pole and PrFeB as a magnet at liquid nitrogen temperature (77K), even higher peak field (∼ 0.94 T) can be achieved at the same gap.
