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. This is the first large scale accelerator which will be built in Iran. For storage ring, booster synchrotron and linac including the transfer lines, a draft design will be completed soon. The storage ring has an emittance of 3.3 nm-rad, a circumference of 297.6 meters with an overall of 32 straight sections of different lengths. The booster synchrotron has a circumference of 192 meters and emittance of 35nm-rad. For the booster synchrotron a new lattice is proposed. The linac is a conventional 150 MeV accelerator. The different accelerator components, magnets, girders, power supplies, vacuum systems etc are in the design phase. State of the art design for different components is employed through international collaboration.
