摘　　要：设计和测试了一套在重离子熔合反应中同时测量蒸发剩余核的质量和电荷的飞行时间谱仪和ΔE-E望远镜双鉴别系统。实验结果表明,该系统对粒子的鉴别能力,Z分辨率好于25,质量分辨可达45。A double particle identification system of time-of-flight and △E-E telescope has been designed and tested for measuring M and Z of the residues in heavy ion fusion reactions simultaneously. Experimeneal resultes showed that the charge resolution of this system is better than 25 and the mass resolution is 45.
