中国科学院原子核研究所1.2米迴旋加速器系我国自制第一台迴旋加速器。本文简要介绍国产1.2米迴旋加速器及其主要工艺系统的安装调整经验和技术性能。这台加速器的主机是仿照中国科学院原子能研究所同类型加速器设计制造的。在设计制造过程中,结合我国具体情况对加速器的某些部分作了一些修改,主要有以下几点: Institute of Nuclear Research, Chinese Academy of Sciences 1.2-meter cyclotron is the first cyclotron made in China. This article briefly introduces the domestic 1.2 m cyclotron and its main process system installation and adjustment experience and technical performance. The host of this accelerator is modeled on the same type of accelerator designed and manufactured by the Institute of Atomic Energy, Chinese Academy of Sciences. In the process of design and manufacture, we made some revisions to some parts of the accelerator according to the specific conditions in our country. The main points are as follows:
