在IUCF和Saturne II加速器上成功地建造了一个用于研究轻离子诱导反应碎裂过程的低阈值带电粒子探测器阵列。该阵列由162个三元件探测器望远镜组成，安装在球形几何形状中，立体角覆盖4π的74%。望远镜元件由（1）一个轴向场气体电离室（用C3 F8气体操作）、（2）一个0.5 mm厚的钝化硅探测器和（3）一个2.8 cm厚的CsI（Tl）闪烁晶体（带光电二极管读出）组成。在0.7 ≤ EA ≤ 95 MeV/核子的动态范围内，对Z ≤ 16的抛射体进行了离散元识别。氢、氦、锂和铍的同位素也被区分为8 E A 95 MeV的喷射物。定制设计的电子器件用于偏置电源和线性信号处理。通过CAMAC/VME/以太网系统采集数据。
A low threshold charged particle detector array for the study of fragmentation processes in light-ion-induced reactions has been constructed and successfully implemented at the IUCF and Saturne II accelerators. The array consists of 162-triple-element detector telescopes mounted in a spherical geometry and covering 74% of 4π in solid angle. Telescope elements are composed of (1) an axial-field gas ionization chamber operated with C3F8gas; (2) a 0.5 mm thick passivated silicon detector, and (3) a 2.8 cm thick CsI(Tl) scintillation crystal with photodiode readout. Discrete element identification is obtained for ejectiles up to Z ∼ 16 over the dynamic range 0.7 ≤ E A ≤ 95 MeV/nucleon . Isotopes are also distinguished for H, He, Li and Be ejectiles with 8 ≲ E A ≲ 95 MeV . Custom-designed electronics are employed for bias supplies and linear signal processing. Data are acquired via a CAMAC/VME/Ethernet system.
