GAMMA RAY SPECTROMETER DATA PROCESSING PROGRAMS,

Two computer programs have been written to analyze and display plot the spectral output of two different gamma-ray spectrometers. These spectrometers are the anti-Compton spectrometer currently in use in NOLs Van de Graaff facility and the Deep Underwater Nuclear Counter DUNC. Both programs have been written for use with an IBM 7090 computer. The program for the anti-Compton spectrometer adds subtracts in variable amounts spectra which are stored in one half of a multichannel analyzer to those stored in the other half. It also performs necessary energy or total count normalization, calculates statistical errors and displays the processed data on linear or semi-logarithmic plots. The DUNC program is used to prepare magnetic tape from a paper punch tape output of a multichannel analyzer. It also searches the magnetic tape for spectra to be normalized, operated upon arithmetically and displayed in printed, punched card or graphic form on the CalComp plotter. Author
