Title: Overview of undulators and wigglers for the NSLS

This summary is designed to present to the NSLS user community the possible options for wigglers and undulators. The desire is to make it possible for every user to respond to the request by the NSLS for guidance in insertion device development so that it can best serve their scientific interests. There are many options, each with its own advantages and disadvantages, as well as certain restrictions imposed by the parameters of the NSLS storage rings. The NSLS is asking for input in two areas. First, we must decide on the instrumentation to be developed for the high field superconducting wiggler beam lines and for the hybrid permanent magnet wiggler lines. Secondly, the long-range plans for additional insertion devices are now under discussion. Choices must be made between the large number of different magnets which can be built. To facilitate user response, we provide a review of the properties of wigglers and undulators, introducing the basic concepts and defining the fundamental parameters. A detailed account of the brightness of the undulator source is presented and the insertion devices already under construction for the x-ray and VUV rings are discussed. We describe the suitability of certain proposed undulators for the generation of soft x-rays (5 to 50A), and harder x-rays (3 to 12A).
