The research facility provided synchrotron radiation to a large number of experimental stations and had an operating cost of approximately £20 million per annum. SRS had been operated by the Science and Technology Facilities Council. The SRS was closed on 4 August 2008 after 28 years of operation. Following the closure of the NINA synchrotron, construction of the facility commenced in 1975 and the first experiments were completed using the facility by 1981.
