The IPERION HS proposal aims at establishing and operating an Integrating Activity for a distributed pan-European research infrastructure, opening key national research facilities of recognised excellence in heritage science. Heritage science is a young and cross-cutting scientific domain embracing a wide range of research disciplines enabling deeper understanding of the past and improved care for the future of heritage. Since 2016, heritage science is included in the ESFRI Roadmap as one of the strategic areas in the domain of Social Sciences and Humanities, where it is represented by the ESFRI Project E-RIHS (European Research Infrastructure for Heritage Science). IPERION HS will provide to the advanced community of heritage science - built and reinforced with the support of four EU projects spanning across four Framework Programmes, approaching 20 years of constant service to the heritage domain - a further level of pan-European integration, in view of the establishment of E-RIHS. IPERION HS is a further step towards a unified scientific approach to the most advanced European instruments for the analysis, interpretation, preservation, documentation and management of heritage objects in the fields of art history, conservation, archaeology and palaeontology. IPERION HS core activity will be offering Trans-National Access to a wide range of high-level scientific instruments, methodologies, data and tools for advancing knowledge and innovation in the domain. In addition, IPERION HS will contribute joint innovative research for a better interoperability not limited to data, but including sample materials, methods and instruments. The networking activities in the project aim at reinforcing the binding in the group and at creating a sense of belonging for heritage science researchers which will exploit the RI services. IPERION HS consists of partners from 22 Countries clustered around their national nodes.

Within the field of security, Customs and Border inspection have not had breakthrough technological developments in the last 20 years, since the introduction of X-ray screening. The limits of these current technologies are accentuated by the increasing diversity and novelty in trafficking materials, tools and methods. These limitations combined with the growing needs of inspection and control call for a disruptive innovative solution. Wanting to move a step up from the existing planar scanning methods with limited material identification results, several studies have identified potential solutions focused on: - High energy 3D X-ray tomography - Neutron interrogation/photofission - Nuclear resonance fluorescence (NRR) While these show good results and performances, they also have several important drawbacks, which limits their possible uses. Moreover, these solutions do not have common technological bricks meaning they can only lead to separate disposals. The proposed MULTISCAN3D investigates a new all-in-one system whose purpose is to become simultaneously a user-friendly, flexible, relocatable solution offering high-quality information for: - Fast high energy 3D X-rays tomography (as first line) - Neutron interrogation/photofission (as second line) - Narrow gamma ray beam based NRR (as second line) MULTISCAN3D will start by investigating and defining needs and requirements, in a technologically-neutral way, with Europe’s most prominent Customs Authorities which will be translated to technical specifications. The main body of the research will be focused on three parts, following which, lab validations and real-environment demonstration will be carried out. These three work areas are: - Laser-plasma based accelerators as X-ray sources - 3D reconstruction for multi-view configurations and data processing - Detectors and source monitoring At the same time complementary techniques with chemical and SNM identification capabilities will be investigated.

Nuclear astrophysics studies the origin of the chemical elements: from the Big Bang, to stellar burning, and to neutron star mergers. ChETEC-INFRA networks the three types of infrastructures that, together, provide the capabilities needed for this quest: astronuclear laboratories supply reaction data, supercomputer facilities perform stellar structure and nucleosynthesis computations, and telescopes and mass spectrometers collect elemental and isotopic abundance data. ChETEC-INFRA will overcome existing barriers to progress: Specifically, we will unify access to nuclear astrophysics research infrastructures using a novel integrated web portal. We will develop improved nuclear reaction targets and detectors, open-source nucleosynthesis software tools, and three-dimensional model atmospheres for stellar spectral analysis based on up to date physics. We will pioneer complementary techniques to address the same science case, and we will link telescopes to nuclear labs and supercomputers. ChETEC-INFRA provides the community with the tools needed to address key questions on solar fusion, neutron capture nucleosynthesis, and explosive stellar processes. In a combined approach designed to facilitate and boost accessibility, synergies and training, the large amount of transnational access provided will enable projects exploiting at least two different types of infrastructures. Within ChETEC-INFRA, data are archived and catalogued for long-term sustainability beyond the end of the project, ranging from evaluated nuclear reaction rates to detailed abundance data for a multitude of stars to tracer nucleosynthesis calculations. ChETEC-INFRA will reach out to PhD students, secondary school students, and to the detector industry. The ChETEC-INFRA community builds on the success of the ChETEC COST Action CA16117 (Chemical Elements as Tracers of the Evolution of the Cosmos). ChETEC-INFRA is networked with the nuclear astrophysics communities in the United States, China, and Japan.
