Improved Computerized Acquisition and Analysis of Gamma Ray Spectra

A new minicomputer based gamma spectroscopy system supports concurrent operation of up to four detectors, with 8k channels per detector. The minicomputer employs 896 kilobytes of RAM and a 25 megabyte hard disk, and runs under a multiuser operating system. Spectral analyses use algorithms adapted from the GAUSS V computer code and optimized for use on a minicomputer. Major improvements include peak location, baseline determination and background correction functions. Nuclide identification uses a library of up to 300 nuclides with up to 24 gamma lines for each nuclide. Upper limit values can be calculated for operator specified nuclides which are not detected by the measurement. Utilities available include nuclide library editing, energy calibration, efficiency calibration and graphic display of selected energy ranges from one or two spectra.
