Description
The rapid development of high-energy particle colliders has significantly increased accelerator power consumption, reaching an annual terawatt-hour (TWh) scale. Such high energy consumption limits the sustainable operation of high-energy physics facilities, making efficiency optimization essential for next-generation accelerators. To address the low energy efficiency and substantial power loss of conventional continuous-wave RF power sources, this paper proposes a multi-mode energy recovery high-voltage power supply based on a modular cascaded architecture. The adaptability of two key technologies, the multi-stage depressed-collector klystron (MSDC) and energy recovery RF power load, is investigated and validated. This further improves the energy-saving technical system and establishes a complete energy recovery system covering power supplies, microwave devices, and terminal loads. On this basis, a complete energy recovery system covering power supplies, microwave devices and terminal loads is constructed to improve the energy-saving technical system. Simulations and prototype experiments demonstrate that the proposed integrated scheme effectively reduces invalid energy dissipation and boosts the overall accelerator efficiency. This paper also explores multiple energy-saving strategies, including operation mode optimization, residual energy recovery and multi-module collaborative efficiency enhancement, and discusses the application potential of the developed technologies in large-scale collider facilities. This study provides reliable technical support for the design of low-carbon, sustainable accelerator systems.
