Description
To enhance the energy efficiency and cost-effectiveness of large-scale particle accelerator facilities, energy recovery has emerged as a key research direction. From the perspective of radio frequency (RF) power sources, this article reports on the latest research progress in this field at IHEP. First, the fundamental principles of energy recovery based on RF power sources are elaborated, covering three aspects: energy recovery klystrons based on multi-stage depressed collectors, high-power RF energy recovery systems, and studies on high-efficiency power recovery devices.
The article highlights recent key technological breakthroughs, including:
(1) Research on energy recovery schemes, which are expected to increase klystron efficiency to over 90%;
(2) RF energy recovery, detailing advancements in RF devices and RF-to-DC conversion technologies;
(3) Design and preliminary experiments of energy recovery devices, demonstrating recent progress in efficiency improvement and energy recovery.
By integrating RF power systems with energy recovery technologies, this work explores potential solutions for highly efficient continuous-wave high-average-power devices. The article aims to provide valuable insights for the design and optimization of future high-efficiency accelerator RF power systems.
