Low emittance pre-injection system for Iranian Light Source Facility

In this paper, we introduce the Iranian Light Source Facility (ILSF) pre-injection system. The optimized parameters of its components, the related beam dynamics issues and the expected performance of the designed system have been described with detail. This paper explains fabrication procedures of some main components and gives the low power microwave measurement results of the constructed RF electron gun. The outcome bunches at the end of the ILSF pre-injection system will have the normalized emittance of 6 mm mrad, length of 1.55 ps and energy spread of 0.06%.
