| 摘 要： | 本文使用EPBS方法分析了含氚及含氘与氚钛膜样品中氚及氘的含量与深度分布,并将氚的分析结果与PVT方法所给出的结果进行了比较.实验所使用的Ti膜衬底是Mo,在EPBS能谱的低能端, Mo元素的模拟谱与实验谱偏差较大,会导致分析结果不准确.为消除EPBS实验谱中的Mo谱对分析的影响,本文使用了一个Mo衬底的TiH_(1.81)样品成功扣除了EPBS实验谱中的Mo本底,扣除Mo本底后可以直接模拟样品中氘与氚的能谱,使得分析结果更为精确可靠.

| Abstract: | Enhanced proton backscattering spectrometry (EPBS) method was utilized in this paper for tritium/deuterium analysis in titanium film, and the results of tritium obtained by EPBS method were compared with PVT method. The substrate of Ti films used in our experiment was thick Mo slab, the experimental spectrum of Mo at low energy region cannot be fitted well, which may lead to inaccurate results. Therefore, a TiH1.81 film with thick Mo substrate was used to remove the influence of Mo background yield in experimental spectra. After subtracting the Mo background yield in experimental spectra we can fit well the tritium and deuterium spectra directly, which could make the results obtained by EPBS method more accurate. |
