Second version of the open-source software GSA for gamma-ray spectrum analysis

Abstract

The collaboration among the PRESN team, LaMCScI laboratory and CNESTEN center made it possible to implement the first version of the GSA software. Its first version is already available to the public; it is not only free but also an open source, demonstrating the developers' commitment to promoting the open sharing of scientific knowledge. This first version is characterized by its flexibility and non-commerciality, and it is available without any conditions on the following website: https://www.github.com/LAHCEN-EL-AMRI/Gamma-Spectra-Analysis, allowing users to add personal options, making it a particularly adaptable tool to the different requirements of scientific research. This article deals with the second version of GSA, which focuses on a core and complementary feature: the calculation of isotope activity. In order to accomplish this goal, instead of implementing a single efficiency formula, as is often the case in most software, four formulas were integrated. The users can therefore select the one they want to implement. To ensure the accuracy and reliability of this new feature, a validation was performed on GSA. The results obtained with GSA v2 were carefully studied by comparing them to those obtained with the renowned Genie 2000 software. Owing to this comparison step, it was possible to verify and confirm the accuracy of the results of GSA version 2. This second version of GSA is available as a free and open source software on the following site: https://www.github.com/LAHCEN-EL-AMRI/GSA-v2/tree/master.
