Feasibility of Interfacing a Microcomputer with a Multichannel Analyzer to Perform Gamma Ray Spectroscopy

摘要

Interfacing a microcomputer to a Nuclear Data Series 2200 multichannel analyzer has been demonstrated. Programs for data transfer, peak detection, peak net area integration, peak centroid location, and energy calibration were written. Data transfer and peak detection scan were demonstrated on 4096 channel spectra in less than 5 minutes. Multibyte integer arithmetic routines for the 8080 microprocessor were written to conserve space and time. A proposed system for gamma ray spectrum analysis is described in hardware and software terms. The hardware for the proposed system would cost less than $9000 while commercial multichannel analyzers with the same capabilities would cost in excess of $23,000.
