The INAA-INRIM software version 3: presentation and validation of results

Abstract Automation in Instrumental Neutron Activation Analysis is present in almost every aspect of the measurement process, from the irradiation, to counting, to the elaboration of results. For the latter task a lot of dedicated software were developed over the years; among them, the k0-INRIM allowed to produce GUM-compliant uncertainty budgets. However, modeling and design limitations hampered its usability in routine analysis. This paper presents the main features of the newly released INAA-INRIM software, which expands the functionalities of k0-INRIM (introduction of model for direct comparator, multiple counting positions, multiple spectra for same sample, managing of multiple measurements) while keeping the focus on the uncertainty from its predecessor. Notable updates are described and results of an analyzed reference material are reported as evidence supporting software validation.
