在线同位素分离器(BRISOL)是串列加速器升级工程的重要组成部分之一。BRISOL采用回旋加速器产生的100 MeV质子打靶产生放射性核素,电离后形成放射性束流,再经质量分析后供物理用户使用,其最大质量分辨率为20 000。BRISOL的谱仪由四块二极铁组成,采用高低电位大小铁反对称结构消除能散,其中前两块磁铁偏转半径为550 mm,偏转角度90°,后两块磁铁偏转半径2 500 mm,偏转角度100°。BRISOL束线的7块磁铁于2012年完成加工及验收,并运抵中国
Online Isotope Separator (BRISOL) is one of the key components of tandem accelerator upgrade project. BRISOL generates a radionuclide from a 100 MeV proton target created by a cyclotron. After ionization, BRISOL forms a radioactive beam and is mass-analyzed for physical use. The maximum mass resolution is 20,000. BRISOL spectrometer consists of four diodes, the use of high and low potential iron anti-symmetrical structure to eliminate energy dispersion, in which the first two magnets deflection radius of 550 mm, deflection angle of 90 °, the latter two magnets deflection radius of 2 500 mm, Deflection angle 100 °. Seven magnets of the BRISOL beam line completed processing and acceptance in 2012 and arrived in China
