Development of Beijing Radioactive Ion Beam Facility Isotope Separator On-line

摘要: 北京放射性核束装置在线同位素分离器（BRISOL）采用100 MeV、200 μA回旋加速器提供的质子束打靶产生中、短寿命放射性核束，进行在线分析后供物理用户使用，其质量分辨率好于20 000。BRISOL装置现已建成，并开展了氧化镁、氧化钙靶的在线实验，在线产生了³⁷K⁺、³⁸K⁺、²⁰Na⁺、²¹Na⁺等多种放射性核束。本文详细介绍该装置的研制及运行情况。

Abstract: The Beijing Radioactive Ion Beam Facility Isotope Separator On-line (BRISOL) is a radioactive ion beam facility based on a 100 MeV and 200 μA cyclotron. The radioactive ion beams are produced by bombarding the thick target with proton beam provided by cyclotron. The resolving power of the BRISOL is better than 20 000. The construction of the BRISOL facility was completed, and the radioactive ion beams of ³⁷K⁺, ³⁸K⁺, ²⁰Na⁺, and ²¹Na⁺ were produced by bombarding CaO and MgO targets with 100 MeV proton beam. The detail of the BRISOL facility was introduced in this paper.
