Magnetic measurements of permanent magnet insertion devices at the BNL-NSLS

摘要

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 Laboratory 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 T, respectively. Some results of point and integral magnetic measurements performed on these magnets are presented.
