国产1.2米迴旋加速器,自1964年9月经国家鉴定合格,投入运行已有一年。一年来,在我国社会主义革命与社会主义建设新高潮的形势鼓舞下,我所加速器工作人员同所内有关研究室一起,逐步熟悉加速器的运行技术与实验技术,初步开展了各方面的实验工作,并提高了加速器的性能。本文简要介绍一年中开展的实验工作,束流状况,设备性能,运行效率以及存在的问题。 Domestic 1.2-meter cyclotron, since 1964 by the national accreditation, put into operation for a year. Inspired by the situation of our country’s socialist revolution and the new upsurge of building socialism over the past year, our accelerator staff members, along with the relevant research institutes in the institute, are gradually familiar with accelerator operation and experimental techniques and have conducted preliminary experiments in various fields. And improve the performance of the accelerator. This article gives a brief overview of the experimental work carried out during the year, the beam conditions, equipment performance, operating efficiency and problems.
