Combination of On-line Analysis with Collection of Multicomponent Spectra in an On-line Computer

A digital computer has been interfaced to four 256-channel analyzers. All functions of normal multichannel analyzers have been reproduced by suitable coding. In addition, a weighted least-squares method for estimating on line the contribution of individual radionuclides in a multicomponent pulse height spectrum has been incorporated. Details of the mathematics and coding methods, which include special modifications to an existing FORTRAN system for on-line use, are described.
