摘　　要：本文描述了一套放射性核次级束流引起反应测量的实验装置，它由次级束流鉴别、测量系统、次级靶控制系统和次级反应产物鉴别、测量系统组成。高增益分组延迟线读出、重心定位ＰＰＡＣ、横向场ＩＣ、椭球面镜聚焦、ＰＭＴ读出、闪烁薄膜时间拾取探测器、双叠层纵向场阳极分条读出ＩＣ、ＰＭＴ矩阵读出了Ｘ－Ｙ位置灵敏Ｐｈｏｓｗｉｃｈ闪烁探测器、康普顿抑制ＨＰＧｅγ探测器等单元是这套装置的基本部件。RIBLL terminal experimental setup consists of RIB identification system,secondary target control systemand secondary reaction preducts measurement system. The high gain X-Y position sensitive PPAC with delay ca-ble groupod readout,the scintillation foil time pickup detector,focusing with carving ellipse surface,transversefield IC,the large area two-dimensional position sensitive scintillator with PMT matrix readout,the comptonsuppressed HPGe γ ray detectors,twinlongitudinal field IC are major components,Nowadays,this setup hasbeen installed at RIBLL terminal.The porformance measurements and test experments are in progress.(
