摘要

中子带宽限制斩波器是中国散裂中子源（CSNS）飞行时间型中子散射谱仪中用于选择特定波段范围中子的装置

其控制系统要求能够实现斩波器相位信号与加速器定时信号同步并完成对斩波器运行状态监控的功能。本文针对控制指标的要求

阐述了控制系统的结构、控制原理及软件设计方案

并对系统控制精度和稳定性进行了分析。

Abstract

The time-of-flight neutron scattering spectrometer in CSNS(China Spallation Neutron Source) will use a bandwidth-limiting(BWL) neutron chopper for choosing neutrons of certain band ranges.Its control system should synchronize the phase signal of BWL neutron chopper with the timing signal from accelerator

and monitor operation status of the neutron chopper.In this article

we describe the structure of control system

the control principle

and the software design.Test results of the controlling accuracy and operation stability of the control system are given

too.
