  Iranian light source facility is a 3 GeV storage ring with a booster ring which is supposed to work at 150Kev injection energy and guide the electrons to the ring energy 3GeV. In this paper magnet design of the booster ring is discussed. It consists of 50 combined bending magnets in 1 type, 50 quadrupoles and 15 sextupoles in 1 family. Using POISSON, Maxwell Ansys and Radia codes, two and three dimensional pole and yoke geometry was designed, also cooling and electrical calculations have been done.

  The Iranian Light Source Facility (ILSF) is a new 3 GeV synchrotron radiation laboratory in the design stage. The ILSF storage ring (SR) is based on a Five-Bend Achromat lattice providing an ultr-alow horizontal beam emittance of 0.48 nm-rad. The ring is consisting of 100 pure dipole magnets, 320 quadrupoles and 320 sextupoles. In this paper, we present some design features of the SR magnets and discuss the detailed physical and mechanical design of these electromagnets. The physical designs have been performed relying on two dimensional codes POISSON [1] and FEMM [2]. Three dimensional RADIA [3] and MERMAID [4] were practiced too, to audit chamfering values and get the desired magnetic length.

  Electron storage rings are extensively used for high luminosity colliders, damping rings in high-energy physics and synchrotron light sources. To further increase the luminosity at the colliders or brightness of a synchrotron light sources, the beam emittance is being continually pushed downward. In this paper, we investigate the lattice design for the storage ring of Iranian Light Source Facility (ILSF) with an ultra-low emittance, intermediate energy of 3 GeV and circumference of 528 m. We present the design results for a five-band achromat lattice with the natural emittance of 276 pm-rad. The base line is based on 20 straight sections with the length of 7 m.

  The Iranian Light Source Facility Project (ILSF) is a 3rd generation light source with energy of 3 GeV, a full energy injector and a 150 MeV linac as pre-injector. The stored beam current in top up mode is 400 mA, the beam lifetime is about 7 h, and the average pressure of vacuum chamber is approximately 1.33 × 10-7 Pa (1 nTorr). The ILSF storage ring has been designed to be competitive in the future operation years. Some prototype accelerator components such as high power solid state radio frequency amplifiers, LLRF system, thermionic RF gun, storage ring H-type dipole and quadruple magnets, Hall probe system for magnetic measurement and highly stable magnet power supplies have been constructed in ILSF R&D laboratory.

  Regarding user requirements of spectromicroscopy beamline such as high flux, small spot size, linear and circular polarization light, a helical undulator have been chosen as a source for this beamline. Radiation properties of the source e.g. flux, flux density, brilliance, size and divergence of the photon beam, power, power density, angular distribution of power and flux on the axis of the undulator have been considered by theoretical formula and using SPECTRA code. At the circular polarization, the first harmonic covers the energies in the 100-1300 eV range and for the linear polarization energy ranges, 100-1000 eV and 1000-1500 eV, are provided by the first and third harmonics respectively. In the case of circular and linear polarization mode, maximum flux in the central cone for maximum undulator strength are 4.5 × 1016 (ph/s) at kX=ky=3.6 and 2.4 × 1016 (ph/s) at K=5.
