摘要：

Two APPLE II type twin undulators are installed at BESSY II. They can either be operated in a chicane mode providing variable polarization at high switching rates or in a combined mode using a modulator for phase adaption. Studies on magnet block inhomogeneities have started to further improve the field quality and to reduce the effort on shimming. (C) 2001 Elsevier Science B.V. All rights reserved.
