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.

Solid state RF power amplifiers have been considered as an attractive candidate for providing the high power RF power required in increasing number of accelerator applications in recent years. Due to the advantages of these amplifiers and based on the successful experience done in other light sources; ILSF RF group has started R&D in design and fabrication of solid state amplifiers. Two modules based on two different LDMOS transistors have been developed successfully at 500MHz. The measured characteristics are presented and compared in this paper. Combining of 8 such modules is under test to achieve 4kW output power as the first stage of the conceptually designed combining network. This paper outlines the design concept of the different parts of the amplifiers and presents the experimental results obtained so far.

We present a program for the design and construction of a thermionic cathode RF gun to produce bright electron beams, consisting in the first step toward the possible development of S band linac based pre-injector at Iranian Light Source Facility (ILSF). The program is aimed at the goal to attain a beam quality as requested by ILSF. As a first step within this mainstream, we are currently developing a thermionic cathode side coupling RF electron gun which is expected to deliver 100 pC bunches with emittances below 2 mm-mrad at 2.5 MeV. We report the performed simulation and design activity, as well as cold test results of first fabricated prototype, which are in good agreement with simulation results.

The Iranian Light Source Facility (ILSF) RF system was conceptually designed based on ILSF requirements for a 3GeV storage ring and 400 mA beam current at 500 MHz RF frequency. The development of HOM damped cavity with simpler structure at 100MHz and advantages of reducing frequency as investigated at MAX Lab, provided an alternative of 100MHz RF system to be explored for ILSF. RF frequency change and its effects on the beam and machine parameters as well as the availability and cost of RF system components have been studied for ILSF. The conceptual design of a 100MHz RF system and the comparison between 500 MHz and 100 MHz RF frequencies are presented in this report. This paper, furthermore, provides details about the 100MHz RF cavity designed by ILSF RF group based on MAX Lab cavity.
