The Iranian Light Source Facility Project (ILSF) is a 3 GeV third generation light source with a current of 400 mA which will be built on a land of 50 hectares area in the city of Qazvin, located 150 km West of Tehran. ILSF conceptual design report, CDR, was published in October 2012. To have a competitive leading position in the future, 489.6 m storage ring of ILSF is designed to emphasize on small emittance electron beam( 0.93 nm-rad), high photon flux density, brightness, stability and reliability. Moreover, 40% of 489.6 m ring circumference is straight sections (14×8 m+ 14×6 m) which are long enough for the commonly used insertion devices. 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.
