研制了屏栅电离室+ΔE-E望远镜探测器系统,系统的屏栅电离室用来测定252Cf自发裂变碎片的能量和相对于探测器系统轴线的发射角,与屏栅电离室耦合安装的ΔE-E望远镜探测器由一个薄的屏栅电离室(气体ΔE)和一个金硅面垒探测器(E)组成,用来确定互补碎片的电荷。用本系统对252Cf自发裂变碎片电荷分布进行了4个参数的关联测量,结果表明,这个探测器系统的电荷分辨能力Z/ΔZ好于40∶1。
The screen ionization chamber + ΔE-E telescope detector system was developed. The system’s grid ionization chamber was used to determine the energy of 252Cf spontaneous fission fragments and the emission angle relative to the detector system axis, which was coupled with the grid ionization chamber. ΔE The -E telescope detector consists of a thin grid ionization chamber (gas ΔE) and a gold silicon surface barrier detector (E) to determine the charge of the complementary debris. Using this system, we measured the charge distribution of 252Cf spontaneous fission fragments by four parameters. The results show that the charge resolution of this detector system is better than 40: 1.
