反符合屏蔽4πβ计数器3He中微量3H2分析装置
A microanalytic anticoincidence 4πβ counter for 3H 2 in 3He
【摘要】 介绍了一种低本底微量气态氚测量装置的结构、性能以及2He中微量3H2的分析结果。它具有结构简单、动态精度高等优点,定量测量下限为N(3H2)/N(3He)<10-11。
【Abstract】 A microanalytic 4πβ counter with anticoincidence shield for 3H 2 in 3He is introduced. As a low background microanalysis device of gaseous tritium, this instrument has advantages such as simple structure, high accuracy and low detection limit [N ( 3H 2) /N( 3He)<10 -11 ]. In this paper the structure and main performance of the counter is described and the test results for 3H 2 in 3He are given.
