摘　　要：描述了用放射性核束进行首次物理实验所使用的探测器系统的构成及各类探测器的性能，同时给出了该系统用于物理实验所得到的令人满意的在线获取结果。A detector system used in the first physics experiment on RIBLL which consists of a position sensitive gas filled detector, an array of surface Si(Li) detectors and an array of neutron detectors was described. The performances of the detectors in the system were tested. A position resolution of 2 mm and energy resolutions of 0.4% for thc c' α particles and 25keV for 137 Cs inner conversion electrons were obtained. A satisfactory on line experiment result was given in the paper.
