在北京串列实验室建立了次级束流实验装置, 用于放射性核束物理和核天体物理研究. 先后开展了7Be(d, n) 8B, 11C(d, n)12N, 8Li(d, p)9Li 和 6He(p, n)6Li核天体物理重要反应的研究. 介绍了串列加速器升级工程的进展情况. 该工程在现有串列加速器的基础上, 将建立100 MeV/200 μA的质子回旋加速器、在线同位素分离器和超导加速段. 在此装置上, 将可以产生质量数最高为120, 强度最高为109 particles/s的放射性束流.
A secondary beam line (GIRAFFE) at the Beijing Tandem accelerator lab was constructed for yielding low energy secondary beams. The current progress on the study of nuclear astrophysics and nuclear structure is presented. Up to now, We have carried out measurement of 7Be(d, n) 8B, 11C(d, n)12N, 8Li(d, p)9Li, and 6He(p, n)6Li reactions. The proposed Beijing radioactive nuclear beam facility (BRIF ) and its current R&D progress are briefly introduced. This facility is based on the existing HI-13 tandem accelerator. A proton cyclotron will be built to provide 100 MeV 200 μA proton beam, together with an ISOL system and a super conducting heavy ion LINAC. By this facility, intensity of order of 109 particles/s radioactive nuclear beams for mass up to A=120 will be produced.
