The Physics Society of Iran Iranian Journal of Physics Research 1682-6957 17 2 2019 11 26 Designing an ultra-low emittance electromagnetic lattices for Iranian Light Source Facility storage ring Designing an ultra-low emittance electromagnetic lattices for Iranian Light Source Facility storage ring 151 158 1245 FA I Ahmadi S M Jazayeri J Rahighi M Mollabashi F Saeidi Journal Article 2019 11 26 Storage rings are extensively used for particle colliders, damping rings and light sources. To further increase the luminosity at the colliders or brightness of a synchrotron light sources, the emittance of accelerator beam is being continually pushed downward in storage rings. In this paper, we investigate the lattice design for the storage ring of Iranian Light Source Facility (ILSF) with an ultra-low emittance of 0.27 nm-rad, intermediate energy of 3 GeV and storage ring circumference of 528 m. In this design, the base line for installing adjuncts is based on 20 straight sections with the length of 7 m.   Storage rings are extensively used for particle colliders, damping rings and light sources.
