Abstract
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.
