“…Resonances are observed by detecting the prompt-gamma radiation that is directly emitted after neutron capture as a function of the neutron energy. In recent years, attempts to measure both the neutron and gamma energies at the same time have been presented [65][66][67][68], in the so-called bi-parametric configuration, and one can foresee an ample range of applicability to Cultural-Heritage studies.…”

Advances in research in Cultural Heritage see increasing application of a multidisciplinary approach and the combined use of physical and chemical characterization of artefacts that can be used to define their structure and their state of conservation, also providing valuable information in selecting the most suitable microclimatic conditions for the exhibition environment. This approach provides a platform for a synergic collaboration amongst researchers, restorers, conservators, and archaeologists. Existing state-of-the-art technologies for neutron-based methods are currently being applied to the study of objects of historical and cultural interest in several neutron-beam facilities around the world. Such techniques are non-invasive and non-destructive and are, therefore, ideal to provide structural information about artefacts, such as their composition, presence of alterations due to the environmental conditions, inclusions, structure of the bulk, manufacturing techniques, and elemental composition, which provide an overall fingerprint of the object’s characteristics, thanks to the nature of the interaction of neutrons with matter. Here, we present an overview of the main neutron methods for the characterization of materials of interest in Cultural Heritage and we provide a brief introduction to the sensors and detectors that are used in this framework. We conclude with some case studies underlining the impact of these applications in different archaeological and historical contexts.

“…Arcidiacono et al reported the use of a neutron-based quantitative method entitled time-resolved prompt gamma activation analysis (T-PGAA) for the analysis of copper-based alloys. 29 This is a relatively new, technique developed by the authors and undertaken on an instrument designed and built in-house. A high purity germanium detector maintained at 77 K was used to acquire both the photon energy promptly emitted by the irradiated sample and the time at which the prompt gamma ray is detected.…”
