Storage ring design for synchrotron radiation sources

Abstract

Modern storage ring light sources have been very successful in providing high-flux, high-brightness, highly stable photon beams for many scientific applications. Their success is underpinned by sophisticated lattice designs that allow small emittance electron beams to be reached with a large complement of straight sections for insertion devices. The design of such lattices is in continuous evolution, with the most modern trends aiming at diffraction-limited storage rings. In this chapter we review the users’ requirements and their implications on the storage ring design strategies. The rationale of the design based on doublebend achromats (DBA) and triple-bend achromats (TBA) is presented along with the most recent solutions based on multi-bend achromats (MBA) and damping wigglers. The strategies for the optimization of the linear and nonlinear optics are discussed. We conclude with a review of the injection schemes, including nonlinear pulsed kicker injection and the implications of top-up operation.
