摘要

摘要: 介绍了中国散裂中子源(CSNS)直线加速器(Linac)采用的自主研制的束流变压器(BCT)系统。根据CSNS Linac的束流参数、加速器管道的横向孔径和纵向空间，专门设计了BCT进行束流宏脉冲流强的测量。在CSNS Linac试运行阶段成功地测量到了负氢粒子束流的宏脉冲信息，给调束运行提供了有利的保障和支撑。

Abstract: The Beam Current Transformers (BCTs) were designed to measure beam macro-pulse current in China Spallation Neutron Source (CSNS) Linear Accelerator (Linac). The BCT design was based on the CSNS Linac beam parameters, the transverse and longitudinal spaces of the accelerator pipe, etc. Now the BCTs have measured the beam macro-pulse current successfully in commissioning and providing support for operation of the Linac.
