11. It was first tested in 1974 with 68 MeV protons at NAP-M storage ring at INP. 12. A storage ring is a type of synchrotron. 13. Construction of the storage ring was completed in August 2003 and commissioning began the following month. 14. Insertion devices are traditionally inserted into straight sections of storage rings ( hence their name ). 15. Once in the storage ring , the electrons produce x-ray beams that are available for use in experimentation. 16. It is used in some particle accelerators and storage rings to control the emission of particle beams. 17. The ISR was a pair of storage rings that accumulated particles injected by the CERN Proton Synchrotron. 18. It was not until the 1970s that undulators were installed in electron storage rings to produce synchrotron radiation. 19. Gerard K . O'Neill proposed the use of storage rings as building blocks for a collider in 1956. 20. In 1966, work began on the Intersecting Storage Rings at CERN, and in 1971, this collider was operational.
