摘要
快循环同步加速器(RCS)作为中国散裂中子源(CSNS)的重要组成部分,主要功能是接受来自直线加速器加速至80MeV的负氢离子束,通过剥离膜转换成质子束并累计加速到1.6GeV引出,经RTBT传输至靶站打靶产生中子。RCS真空系统是实现这一功能的重要载体。本文从RCS总体布局入手,主要介绍RCS真空系统结构设计、设备布局方式以及泵组分布情况;本文还重点介绍了大型陶瓷真空盒在加速器上的应用情况以及陶瓷真空盒使用前的一些必要工艺:氮化钛镀膜和RF屏蔽。本文最后介绍了RCS真空系统的运行情况。
Rapid cycling synchrotron(RCS)is an important component of China Spallation Neutron Source(CSNS).Its main function is to receive the 80 MeV kinetic energy pulse H-ion beam accelerated by the linear accelerator,and convert it into a proton beam by stripper foil.It is then accelerated to 1.6 GeV,which are extracted and strike a solid metal target to produce spallation neutrons.The vacuum system of RCS is an important carrier to realize the function.This paper starts with the overall layout of RCS,and mainly introduces the structure design,the equipment layout and the distribution of the pumps of the vacuum system of RCS.This work also focuses on the application of large-scale ceramic chamber on accelerators and some necessary pretreatment process for ceramic chamber:TiN coating and RF shielding.The operating status of the vacuum system is introduced at end of the paper.
