摘要
中国科学院高能物理研究所建造了一台基于加速器的硼中子俘获治疗(BNCT)实验装置。射频功率源系统为352.2 MHz射频四极加速器(RFQ)提供高频功率,使束流离开RFQ时,其能量达到3.5 MeV。BNCT射频功率源系统主要包括速调管功率源、数字低电平控制系统、射频传输系统。本文介绍了BNCT射频功率源系统,主要包括物理需求、系统组成、关键设备、安装和调试。目前该装置已进行动物实验,加速器打靶束流功率4.3 kW,加速器射频功率源系统运行稳定。
An accelerator-based boron neutron capture therapy(BNCT)experimental facility has been built by Institute of High Energy Physics,Chinese Academy of Sciences.The radio frequency(RF)power source system provides 352.2 MHz pulse power for radio-frequency quadrupole(RFQ)cavity and the beam energy reaches 3.5 MeV through RFQ cavity.The RF power source system includes klystron power source,digital low-level RF(LLRF)control system,and RF transmission system.This paper will introduce the BNCT RF system including physical requirements,system composition,key equipment,installation and commissioning work.At present,the therapy facility operates for animal tests with the target beam power higher than 4.3 kW.The RF power source system runs stably and reliably in the long-term operation.
