Description
The reliable operation of high-power RF components, including superconducting cavity input couplers and RF windows, is critical for superconducting radio-frequency (SRF) accelerator facilities. Prior to installation into accelerator systems, these components typically require high-power conditioning to verify their RF performance and thermal stability. However, establishing megawatt-level RF test facilities is challenging due to the complexity and limited availability of high-power RF sources.To address this challenge, the Institute of High Energy Physics (IHEP) has developed a 650 MHz traveling-wave resonant ring (TWRR) system,which enables megawatt-level circulating power by accumulating RF energy in a closed-loop structure with a relatively low-power RF source.The system was tested under high-power CW operation. A circulating power of approximately 1.2 MW was achieved with an injected RF power of only 42.7 kW.Stable continuous-wave operation was maintained for 8 h without interruption.These results demonstrate the feasibility of MW-level CW RF conditioning using a compact TWRR and provide an effective test platform for future CEPC RF components.
