论文摘要
启动了光（用于图像引导的强子疗法的LINAC）项目，以开发一个模块化的质子加速器，该质子加速器可提供高达230 MEV的癌症治疗的光束。该机器由三种不同种类的加速结构组成：RFQ（Radio-frice-frice-Quadrupole），SCDTL（侧耦合漂移管LINAC）和CCL（耦合型腔linac）。这些加速结构在750 MHz（RFQ）和3 GHz（SCDTL，CCL）下运行。加速器RF信号由低级RF（LLRF）系统生成，分布和控制。 Light LLF系统基于具有特定于项目定制的仪器技术的市售解决方案。该LLRF系统具有高振幅和相位稳定性，从RF网络监视RF信号以及在200 Hz处的加速结构，RF脉冲在集成的实时接口上整形，RF分解检测以及热谐振频率校正反馈。 LLRF系统控件集成在前端控制器（FEC）中，该控制器将其连接到光控制系统。在此贡献中，我们介绍了AVO LLRF系统的主要特征，其操作和性能。
The LIGHT (Linac for Image-Guided Hadron Therapy) project was initiated to develop a modular proton accelerator delivering beam with energies up to 230 MeV for cancer therapy. The machine consists of three different kinds of accelerating structures: RFQ (Radio-Frequency Quadrupole), SCDTL (Side Coupled Drift Tube Linac) and CCL (Coupled Cavity Linac). These accelerating structures operate at 750 MHz (RFQ) and 3 GHz (SCDTL, CCL). The accelerator RF signals are generated, distributed, and controlled by a Low-Level RF (LLRF) system. The LIGHT LLRF system is based on a commercially available solution from Instrumentation Technologies with project specific customization. This LLRF system features high amplitude and phase stability, monitoring of the RF signals from the RF network and the accelerating structures at 200 Hz, RF pulse shaping over real-time interface integrated, RF breakdown detection, and thermal resonance frequency correction feedback. The LLRF system control is integrated in a Front-End Controller (FEC) which connects it to the LIGHT control system. In this contribution we present the main features of the AVO LLRF system, its operation and performance.
