Abstract

The radio frequency (RF) system is one of the core components of a particle accelerator, providing the energy required to accelerate particles. The Low-Level RF (LLRF) system is responsible for controlling the phase and amplitude of the accelerating field. Compared to analog LLRF systems, digital LLRF systems offer better noise suppression, greater flexibility and extensibility. Therefore, at the Taiwan Photon Source (TPS), we developed and implemented digital LLRF systems for both the booster and storage ring RF systems. The booster's digital LLRF system has been in operation since 2018, while the storage ring's system was commissioned in 2024. This paper describes the design, implementation, and operational experience of the digital LLRF system at TPS.

TPS数字LLRF系统的设计、实现和运行

射频（RF）系统是粒子加速器的核心部件之一，提供加速粒子所需的能量。低电平射频（LLRF）系统负责控制加速场的相位和振幅。与模拟LLRF系统相比，数字LLRF系统提供更好的噪声抑制，更大的灵活性和可扩展性。因此，在台湾光子源（TPS），我们开发并实现了数字LLRF系统，用于升压环和存储环RF系统。助推器的数字LLRF系统自2018年以来一直在运行，而存储环的系统于2024年投入使用。本文介绍了TPS数字LLRF系统的设计、实现和运行经验。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
