摘　　要：介绍了 4 π带电粒子多探测器系统 ,该系统由 2 76个探测器单元组成 ,每个单元分别由快、慢塑料闪烁体、碘化铯晶体、硅半导体探测器所组成的望远镜构成。总立体角覆盖约 86 %的 4 π以及有一个很低的能量探测阈。整个探测器系统轴向对称排列 ,工作在真空中。该探测器系统可以鉴别氢、氦的同位素 ,具有大的能量测量动态范围。A 4π multidetector array of measuring charged particle is described. It consists of 276 detector units, each unit composed of fast and slow plastic scintillator phoswiches, fast plastic scintillator and CsI(Tl) phoswiches and silicon detector telescopes. It covers geometrically 86% of the 4π solid angle and has very low detection thresholds. The detectors, operated under vacuum, is axially symmetric. 1,2,3 H, 3,4 He and the elements from Li to Ar can be identified and their energies measured over a large dynamic range.
