| 本文针对美国CANBERRA公司产8180型多道分析器组成的多道测量系统的主要参数对所测谱的影响进行了探讨.通过对能量为0.66-1.33MeV的γ射线和能量为0.48-1.O5MeV的电子能培的半高宽、谱峰道位及谱峰计数的测量,获得了有关能谱半高宽、谱峰道位和谱峰计数对测量系统主要参数(主放大器放大倍数和主放大器整形时间)响应的大量数据,在对这些数据分析的基础上,给出了该测量系统主要参数的最佳选择范围和最佳选择值. |

| The influence of parameters of 8180 model MCA measuring system on energy Spectra measure was studied. By measuring the full width at half-maximum(FWHM),the position and count of peak in the energy spectra of γ-ray with energy range from 0.66MeV to 1.33 MeV and electron beam with energy range from 0.48MeV to 1.05 MeV,a great number of data in answer to amplifier gain and shaping time were obtained. Based on these data,optimum measuring parameters of the MCA system were proposed. |
