RF systems of two medium energy beam transports (MEBT) have been designed to improve a beam quality. An operating frequency of the MEBT RF system is 350 MHz, and the required RF power is 44 kW for MEBT-1 and 18 kW for MEBT-2. The RF duty is 9% (1.5 ms, 60 Hz), and an RF stability of ±1% in amplitude and ±1° in phase is required. The RF system includes a low-level RF (LLRF) control system, a solid state RF amplifier (SSPA) as a 60 kW SSPA for MEBT-1 and a 30 kW SSPA for MEBT-2, a coaxial circulator, and 3-1/8" coaxial line components. A RF power test to the MEBT has been performed with 4 kW SSPA before the full power operation. The configuration and high power test results of the MEBT RF system are presented in this paper.
