Development of A Solid State RF Amplifier in the KW Regime for Application with Low Beta Superconducting Rf Cavities

Projects based on the use of low beta superconducting cavities for ions are under operation or development at several labs worldwide. Often these cavities are individually driven by RF power sources in the kW regime [1, 2]. For an ongoing project a modular 2 kW, 176 MHz unconditionally stable RF amplifier for CW and pulsed operation was designed, built, and tested In order to optimize the performance of the power transistors and other thermally loaded components an extended thermal analysis was performed to develop a high performance water cooling system. The paper outlines the design concept of the amplifier and presents characteristic experimental results obtained from a series of 6 high power amplifiers.
