Abstract

The magnetic field quality or tolerance for actual insertion devices (IDs) is determined by the storage ring requirements and the acceptable spectral performance. A summary of these tolerance requirements for typical planar permanent magnet undulator IDs on the new third generation synchrotron facility storage rings is presented. In addition, some results for APS prototype undulators are discussed. The major emphasis is to identify the sources of magnetic field errors in real IDs and to describe the effects of these errors on the spectral performance of the device and on the storage rings.<>
