Description
The China Spallation Neutron Source (CSNS) is the first accelerator-based neutron facility in China, situated in Dongguan, the core of the Guangdong-Hong Kong-Macao Greater Bay Area. It provides intense pulsed neutron beams for basic and applied scientific research using neutron scattering, including material science, life science, environmental resources, new energy, and cultural heritage, among others. Thanks to the advantage of neutrons to penetrate deeply into objects, neutron techniques have been applied to study cultural heritage artefacts non-invasively. This presentation will introduce the main neutron techniques at CSNS suitable for the characterization of cultural heritage materials and artifacts. The analytical techniques will include conventional neutron radiography and tomography, Bragg-edge neutron imaging, neutron grating imaging, neutron resonance imaging, neutron diffraction, and complementary X-ray tomography, etc. The talk also includes case studies highlighting the impact of these applications in cultural heritage research area related to manufacturing processes, state of degradation, authenticity and provenance.
