The 4th Generation storage Ring (4GSR) as the second synchrotron light source in Korea was launched from 2021. The 4GSR is designed to be one of the world's best performance with a beam energy of 4 GeV / 400mA. Therefore the RF system is studied and designed with solid-state power amplifiers (SSPA) which are effective RF sources instead of tubes due to the broad studies and applications in the accelerator technics.
The 80kW SSPAs are needed for the booster ring, and 160kW SSPAs are estimated for the storage ring RF system to supply the high power RF to the NC cavities.
This poster describes the present design status and composition of the high power RF system of the booster and storage ring with mainly SSPA as the RF sources.
