摘要
在散裂中子源快脉冲质子同步加速器中,需要对高频加速电压信号的频率、幅度和相位进行精确控制,以实现在规定的时间内完成对质子束团的俘获、加速和引出。采用可编程逻辑门阵列(FPGA)技术,用直接数字合成技术(DDS)或I/Q调制解调技术均可实现对高频腔的控制。本文给出了该方法的基本原理、设计电路及仿真波形。
In the LLRF control system of the CSNS （chinese spallation neutron source）, We have to precisely control the amplitude, phase and frequency of the high frequency acceleration voltage signal in order to get a better accelerating effect for the particles in stated time. We can use DDS or I/ Q modem to control the RF cavity, which was based on FPGA technology. The paper puts forward the fundamental, circuit design and simulation waveform.
