针对输出功率为10GW、脉冲持续时间为160ns的重复强电子束加速器（IEBA），开发了一种基于Delphi和现场可编程门阵列（FPGA）的紧凑型控制系统。系统采用硬件和软件两种解决方案。它由上位机、通信模块和主控单元组成。在上位机上安装了用Delphi设计的与设备无关的应用程序编程接口。分析了电压在重复模式下的稳定性原理，并详细介绍了系统的硬件和软件配置。高压实验表明，该控制系统能够满足远程操作和数据采集的要求。采用基于时序控制方法的控制系统，保证了每次射击时初级电容器电压恒定，保证了电子束加速器在重复模式下的稳定可靠运行。与本实验室开发的基于Labview和PIC单片机的控制系统相比，本系统结构更紧凑，在时间维度上精度更高。在高功率微波效应研究实验中，对脉冲间的可重复性要求很高，这对于IEBA的自动控制尤其有用。
A compact control system based on Delphi and Field Programmable Gate Array(FPGA) is developed for a repetitive intense electron-beam accelerator(IEBA), whose output power is 10GW and pulse duration is 160ns. The system uses both hardware and software solutions. It comprises a host computer, a communication module and a main control unit. A device independent applications programming interface, devised using Delphi, is installed on the host computer. Stability theory of voltage in repetitive mode is analyzed and a detailed overview of the hardware and software configuration is presented. High voltage experiment showed that the control system fulfilled the requests of remote operation and data-acquisition. The control system based on a time-sequence control method is used to keep constant of the voltage of the primary capacitor in every shot, which ensured the stable and reliable operation of the electron beam accelerator in the repetitive mode during the experiment. Compared with the former control system based on Labview and PIC micro-controller developed in our laboratory, the present one is more compact, and with higher precision in the time dimension. It is particularly useful for automatic control of IEBA in the high power microwave effects research experiments where pulse-to-pulse reproducibility is required.
