Operation of the Synchrotron Radiation Center of the University of Wisconsin.

The operation of a 240 MeV electron storage ring as an intense source of synchrotron radiation for a wide variety of investigations in the far ultraviolet and soft x-ray region of the electromagnetic spectrum has been supported by the Air Force Office of Scientific Research through the years 1969-1974. During this period, the performance of the storage ring has been improved and a research facility of international renown has been developed around it. As part of the program that was carried out to bring the storage ring and the research facility that it serves to its present state, a number of optical instruments of advanced design and performance have been developed with the support of the operations contract. Researches in the orbit dynamics of the circulating electrons in the storage ring have been carried out and the results of these studies applied to the storage ring to bring about a large increase in stored beam current and beam lifetime. A 44 MeV electron accelerator of the microtron type was designed and built to replace the original storage ring injector which has resulted in improved reliability in the operation of the storage ring and a reduction in operating costs and power demand.
