摘　　要：针对华中科技大学自由电子激光(free electron laser,FEL)太赫兹源直线加速器束流调节环节存在的开环控制、运行卡顿、数据传输困难、处理滞后等问题,分析了微波功率源谐振频率与加速管腔体温度对束流能散度的影响,以此为理论基础设计了束流能散度自动调节系统。该系统以Labview程序为软件开发平台,包括用户层、数据交互层与物理层3层结构,采用分布式控制方案,分为调束与运行监控2个子系统,子系统间通过实验物理与工业控制系统通讯。该系统界面友好、操作流畅、响应迅速、功能稳定,在高重复频率下使能散度快速达到最佳状态。The beam regulation link of the free electron laser (FEL) terahertz source in Huazhong University of Science and Technology has problems such as open-loop control, running stuck, data transmission difficulties and processing lag. Based on the effect of resonant frequency of microwave power source and acceleration tube temperature, the beam energy spread automatic adjustment system is constructed. The system chooses Labview as the platform of software development, including a three-layer structure of user layer, data interaction layer and physical layer. A distributed control scheme is divided into two subsystems, beam adjustment and operation monitoring. They use experimental physics and industrial control system for communication with each other. Featured by friendly interface, smooth operation, fast response and stable function, the system can make the energy spread approach its minimum quickly under high repetition rate.
