Abstract:

The application of digital computer techniques to the analysis of pulse height spectra is one of the important areas of development of gamma ray scintillation spectrometry. As a result, an increasing interest has developed in techniques for coupling the pulse height analyzer to the computer. An IBM-523 Gang Summary Punch, in conjunction with a specially built buffer unit is used to provide punched card readout from a 256-channel pulse height analyzer. Complete readout is accomplished in 12 seconds. The use of punched cards contributes the additional advantages of an easily organized data file and ready accessibility to the data. The card-punch buffer unit is capable of converting binary coded decimal notation BCD to binary notation. It has an eight-word AND gate matrix which allows the insertion of seven record-identification and information words into the punch card readout, along with the 256 words of pulse height data.
