摘要
中国散裂中子源(CSNS)硼中子俘获治疗(BNCT)实验装置加速器主体由一套速调管功率源和一台RFQ腔体组成,用于给带电粒子提供加速能量。其中,数字低电平控制系统(LLRF, Low Level Radio Frequency control system)用于控制速调管功率源的功率大小,并实现自动老炼、驻波比保护、ARC保护、调频、调谐等功能。本文详细介绍了各个系统的功能以及最终实现的情况。
The Chinese Spall Neutron Source (CSNS) Boron Neutron Capture Therapy (BNCT) experimental facility is an accelerator-based facility. A klystron RF power provides RF power to the RFQ for particle acceleration. The digital low level radio frequency control system (LLRF) is used to control the power of klystron power source, and realize automatic aging, standing wave ratio protection, arc protection, frequency modulation, tuning and other functions. This paper introduces the function and the final realization of each subsystem in detail.
