The Usage of ROOT in Analyzing Gamma-rays with Covell and Total Peak Area Methods

Abstract

ROOT is a framework for a physicist to save data, to access the data, to mine the data and to publish results in a graphical interface. As a gamma ray spectroscopist, one of the most useful features of it is to estimate and to calculate the integral of a peak area. When this is done, not always these peaks can be isolated easily. Also, the methods differ the results of the total counts under the peak areas. Regardless of the detector types, the written C++ codes for ROOT can be easily implemented and adjusted for any peak situation. As an example, Maestro, which is a multichannel analyzer (MCA) emulation software package, is one of the most common software for NaI detector type. However, the users of this package mostly do not know the details of its procedure to collect and integrate the total counts for each individual gamma-ray. For that reason, it will be useful to indicate the comparisons for an experimental data by using Covell and Total Peak Area (TPA) methods between ROOT and Maestro.
