摘要
本文描述用于放射性次级束终端中作△Ｅ测量的大面积（５００ｍｍ×５００ｍｍ）阳极分条读出双叠层电离室的构造和性能。６５ｋＰａ的Ｐ１０气体，对α源（８．７８５ＭｅＶ）的能量分辨为２．５％，并用△Ｅ－ＴＯＦ方法得到了较好的同位素鉴别。
This paper described the structure and performance of a large area ( 500 mm ×500 mm ) twin ionization chamber for the measurement of ΔE on radioactive second beam line. The energy resolution is 2.5% (α source 8.785 MeV ) when the P10 gas pressure is 65kPa. A better isotope identification has been achieved using ΔE TOF method. (
