摘要
为了实现氚量在固态物质中沿深度方向分布的无损测量,采用HpGe探测器结合主放大器、脉冲幅度分析器研发出氚β衰变诱发韧致X射线谱(BIXS)谱仪样机,用于测量氚衰变产生β射线与材料组成原子相碰撞产生连续的轫致辐射X射线谱,可以分析得到氚在材料中的浓度深度分布。针对BIXS谱仪的数据测量与分析要求,基于LabVIEW平台自主开发了BIXS上位机应用软件系统,通过BIXS谱仪与PC间的USB通信及数据传输,具备了谱数据的采集、谱图平滑、寻峰、线性能量刻度(多点能量刻度)、峰面积和分辨率的计算等功能,并在LABVIEW环境下结合对数据库的访问和查询等操作,建立了查找元素的功能,实现了对能谱的定量和定性分析。
Non-destructive measurement of tritium distribution in the depth direction in solid material,using HpGe detector combined with the main amplifier and pulse amplitude analyzer developed β-ray-induced X-ray spectrometry(BIXS) for measuring continuous bremsstrahlung X-ray spectrum produced by the decay of tritium β rays collide with atoms in the material,and can be analyzed to obtain the depth distribution of tritium concentration in the material.BIXS PC application software system based on the LabVIEW platform developed independently for data measurement and analysis of BIXS energy spectrometer requirements,USB communication can transfer data between PC and BIXS energy spectrometer.The system having the function of data acquisition,image smoothing,peak search,linear energy scale(multi-point energy scale),and the calculation of the peak area and resolution capabilities,and also can access and query operations in the database combined with LABVIEW environment to search elements.Quantitative and qualitative analysis for the energy spectrum realized through the software system.
