Development of Two Wigglers at SSRF

As one of main contents of Shanghai Synchrotron Radiation Facility (SSRF) Project, two wigglers with the period length 8 cm (19 periods) and 14 cm (8 periods) by using hybrid magnetic configuration consisting of Nd-Fe-B magnetic blocks and Vanadium Permendur poles are developed. The design, construction and key techniques are introduced, and the results of the magnetic field measurement and tuning are presented. The results show that the parameters of the wigglers can reach the design standard.
