It took a decade to develop the 500-MHz module for the Solid State Power Amplifier (SSPA) in NSRRC. Performance of a single module was gradually improved to reach a steady output power of 960W by using the RF chip IC-BLF578XR. Heat dissipation unit and high-efficiency power supply are key issues in improving integral performance (49.5% RF power) of the single module. A 110-module SSPA tower...
The National Synchrotron Light Source II (NSLS-II) Storage Ring was originally commissioned in 2014 with two 310 kW CW Klystron transmitters supplying their respective cavities with RF power. Late in 2017 the process of procuring a third RF 310 kW CW transmitter for the Storage Ring was started. Proposals from multiple vendors offering both Klystron and Solid-State Amplifier (SSA) solutions...
A solid state LDMOS FET based RF High Power Amplifier (HPA) with 60 kW CW RF output power , operating at 500 MHz, with a power gain ~ 80 dB is being designed and manufactured for the Accumulator Ring (AR) RF cavity in the ALS-U project at LBNL, through a joint effort with a commercial company, R&K. This paper presents the highlights of the important initial planning, installation site space...
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...
