本文简要介绍了最近半年多来BEPC工程进展情况,对撞机主体部份有关的土建大部接近竣工,1.4GeV直线加速器的安装已完成70%以上。前端250兆电子伏区段已经进入调试阶段,并得到了正电子束,贮存环90%以上的非标设备均已完成,除高频腔尚需抓紧研制外,其余的均在进行单部件测试。输运线已于本月初全部安装完毕。环形部份的安装已开始,自控系统的主要部份已在实验室内建立,并发展了一套电源控制系统的软件,闭轨测量显示系统也正在调试,束测系统的部份探头已进入安装。
This article briefly introduces the progress of the BEPC project over the past six months and most of the civil works related to the main part of the aircraft were completed and completed. The installation of 1.4GeV linear accelerator has been completed more than 70%. Front 250 megahertz electron voltage section has entered the commissioning phase, and has been a positive beam, storage ring more than 90% of non-standard equipment have been completed, in addition to the high-frequency cavity still need to pay close attention to the development, the rest are in the single-component test . Transport line has been fully installed earlier this month. The installation of the ring section has begun. The major part of the controlled system has been established in the laboratory and a suite of software for the power control system has been developed. The closed-loop measurement display system is also being commissioned and some of the beam measuring system probes have been entered installation.
