Magnetic measurements of permanent magnet insertion devices at the BNL-NSLS (Brookhaven National Laboratory--National Synchrotron Light Source)
Since June 1988, three permanent magnet insertion devices of the hybrid type have been installed into the x-ray ring at the National Synchrotron Light Source at Brookhaven National Lab. as part of the Phase II facility upgrade. The three magnets consist of a soft x-ray undulator (SXU) and two hybrid wigglers, with peak fields of 0.35 and 1.2 Tesla respectively. The SXU magnet has iron poles, samarium cobalt permanent magnets, 80mm period length, 77 poles, and a gap range of 31--100 mm. For this gap range the undulator parameter K, where K = 0.934 B(Tesla)/lambda/(cm), ranges from 2.6 to 0.15. The hybrid wigglers have vanadium pomander poles, samarium cobalt magnets, 120MM periods, 31 poles, and a gap range of 22--122mm. For this gap range K ranges from 13.0 to 0.5. All three of these magnets have electromagnetic coils which can be powered to adjust the value of the magnet field integral. Both point and integral magnetic measurements were performed on these magnets; some of the measurement results will be presented in this paper.
