Study for Optimum Parameters Digital Nuclear Spectrum System

为建立最优能量分辨的数字化核能谱装置,探讨了一种参数最优化数字核能谱获取系统的设计原理及软件实现,通过对核信号预采样和自学习,给出最优化滤波方案和前端条件线路最佳参数。与相同条件下模拟多道系统获取的能谱相比,该数字化能谱获取系统优于模拟系统。

For development of digital nuclear measurement set with optimum energy resolution, the principle of an optimum parameters digital nuclear spectrum system was advanced. The algorithms were developed, which choose the best digital filter scheme and the best parameters of front-end conditioner, through pre-sampling and system selfstudy. Compared with the results from multi-channel analyse system, the energy resolution from digital system is obviously improved.
