Recently, a major reconstruction of the electron storage ring DORIS II, the DORIS III project, has been completed (W. Brefeld, H. Nesemann, and J. Rossbach, {ital Proceedings} {ital of} {ital the} {ital European} {ital Particle} {ital Accelerator} {ital Conference}, Rome (World Scientific, Singapore, 1988), p. 2389). Figure 1 shows an overview of the new ring. Originally DORIS II had a twofold symmetry. In part C each of the two dipole magnets adjacing to the 65-m-long straight section was replaced by three corresponding weaker ones. In this way a total of seven straight sections for insertion devices are provided. Six of them are 4-m long and the one in the center is only 2.7-m long. After extensive discussions with the user groups involved, four x-ray wigglers, one asymmetric hybrid structure, one x-ray undulator, and one XUV multiple undulator of the revolver type have been proposed for six of the sections (J. Pflueger and P. Gurtler, Nucl. Instrum. Methods A {bold 287}, 628 (1990)). One section is presently still free. All devices are either in construction or have already been completed and installed. In this contribution the mechanical and magnetic design of these devices will be described. Results of magnetic measurements of those devices which are already completed will be given in more detail.
