一台用于AMS的鉴别同量异位素的气体电离室

A GAS IONIZATION CHAMBER FOR INDENTIFICATION OF ISOBARS IN AMS

摘要: 文章描述一台用于加速器质谱计(AMS)的鉴别同量异位素的气体电离室,它由三个分离的阳极、一个栅极和阴极组成。利用这台电离室,在加速器上进行了~(36)Cl的测定。它有效地排除了~(36)S等本底的干扰。

Abstract: In this paper, A gas ionization chamber which consists of 3 separated anodesand a cathode is described for identification of isobars in AMS. The ionizationchamber is used to identify ~(36)Cl. The result shows that the background ions ~(36)Scan be eliminated by the ionization chamber.
