北京放射性离子束装置(BRIF)是国家投资数亿元的大科学工程,现已竣工试运行,填补了我国在IS()L型放射性离子束装置方面的空白。该装置由一台强流质子回旋加速器、离子源、在线同位素分离器和后加速段组成。利用80~100 MeV的强流质子束轰击较厚的反应靶,产生放射性核素;反应产物经离子源电离和在线分离,在线同位素分离段可引出30~300 keV的分离束,质量分 Beijing Radioactive Ion Beam Device (BRIF) is a large-scale science project invested by the state with a total investment of several hundred million yuan. It has been completed and put into trial operation to fill the gap in China’s IS (superscript +) ion beam ion beam device. The device consists of a strong stream proton cyclotron, ion source, online isotope separator and after acceleration section. A strong stream proton beam of 80-100 MeV was used to bombard the thick reaction target to generate radionuclides. The reaction products were ionized and separated online by the ion source. The separation fraction of 30 ~ 300 keV could be obtained from the on-line isotope fractionation separation. The mass fraction
