1 引言多道分析器(Multichannel Analyzer 下称MCA)是核物理实验室的常规设备,更是穆斯堡尔谱仪的基本仪器,它除可做一般的脉冲幅度分析外,还可做波形分析、多定标分析和时间分析.目前常用MCA 的存贮单元数目多为512、1024道或4096道等,一般不具备完善的数据处理功能,测量到的数据往往需先用打印机打印出来,再进行人工计算和分析,这不仅耗费许多时间,而且很难得到精确结果.因此将MCA 所采集的数据直接送入计算机进行处理是很必要的.本文给出一种采用EIA(RS232)串行接口,用计算机软件实现MCA 与计算机数据通信的方法,可克服上述不足之处.
1 Introduction Multi-channel analyzer (Multichannel Analyzer MCA) is a conventional equipment in nuclear physics laboratory, it is the basic instrument of Mossbauer spectrometer, it can do in addition to the general pulse amplitude analysis, but also do waveform analysis , Multi-scale analysis and time analysis.Currently used MCA storage unit number mostly 512,1024 Road or 4096 Road, generally do not have a sound data processing functions, the measured data often need to be printed out with a printer, and then Therefore, it is necessary to send the data collected by MCA directly to the computer for processing.This paper presents a method using EIA (RS232) serial interface , With computer software to achieve MCA and computer data communication methods to overcome these shortcomings.
