| 摘 要： | 在利用回旋加速器质谱技术进行氚断代的测量中,工作气体是电解水样品时收集到的含氚氢气,并混入少许一定量的空气。空气中的微量~3He和样品中的~3H同时加速并被用作参考标准以监督加速器的束流变化。描述了利用金硅面垒探测器望远镜和铝吸收箔的组合来探测和鉴别~3H和~3He的实验方法和结果。

| Abstract: | The cyclotron in SINR has been used as a cyclotron mass spectrometer for tritium dating. The gas introduced into the ion source was 3H- containing hydrogen which collected from electrolysis of water samples and mixed with a certain amount of air in which trace 3He was used as a reference. 3H and 3He ions were accelerated simultaneously. The separation and identification of these two ion species was made by a combination of silicon detector telescope and aluminium absorption foil. |
