The 13th ITER International School (IIS) will be held from 9 to 13 December in Nagoya hosted by National Institute for Fusion Science (NIFS), Japan. The subject of the 2024 school is "Magnetic fusion diagnostics and data science," with a scientific program coordinated by Profs. M. Yokoyama and K. Tanaka (National Institute for Fusion Science) and Drs. M. Kocan and S. McIntosh (ITER Organization). Diagnostics are key to the achievement of ITER fusion power demonstration goals, and they require the application of a wide range of techniques. However, diagnostics are not enough to ensure ITER's success; only through the advanced analysis of the data they provide will it be possible to guide the experiments toward their fusion power goals. It is timely to address these multidisciplinary areas during the 13th ITER International School. The ITER International School aims to prepare young scientists and engineers for working in the field of nuclear fusion and in research applications associated with the ITER Project. The adoption of a "school" format was a consequence of the need to prepare future scientists and engineers on a range of different subjects and to provide them with a wide overview of the interdisciplinary skills required by ITER. https://lnkd.in/gUqUMMzE

HB11 recently collaborated on ‘Equations of State’ experiments at Prague Asterix Laser System (PALS) in the Czech Republic. Proton-boron fuel requires implosion to burn. In order to build a correct model of the implosion process driven by a high energy laser, we need to understand the material properties and behaviour of the boron fuel under extreme pressures and temperatures. This is no simple task as we’re talking about millions of atmospheric pressures and millions to billions of Kelvins (degrees), occurring after petawatts (1,000 trillion watts) of energy have passed through fuel no bigger than a millimetre in size.    This topic is called ‘The Equation of State’ and was part of HB11 Energy’s Collaborative Science Program this month. Scientists from HB11 Energy joined others from the Université de Bordeaux (France), the Institute of Plasma Physics and Laser Microfusion (Poland), GSI Helmholtz Centre for Heavy Ion Research (Germany), the Hellenic Mediterranean University (Greece) and the Soreq NRC (Nuclear Research Center, Israel), to participate in two experiments that were successfully finalised at PALS.   The aim of these experiments was to first prepare a platform to measure the Equation of State of materials in extreme conditions, obtained by laser-driven shock waves, and the study the Equation of State of boron nitride (BN) specifically. The platform prepared employed diagnostics including Streak Optical Pyrometry, Velocity Interferometer System for Any Reflector and Photonic Doppler Velocimetry. The platform was then applied to study the Equation of State of boron nitride (BN) in the Megabar pressure range. This material is interesting as a target material for proton boron fusion, but also, due to its mechanical and thermodynamical properties, it could be used as a candidate to replace synthetic diamond as an ablator for inertial confinement fusion targets. Boron nitride features the hardness of diamonds and a high tensile strength, and is therefore a good candidate for a thinner ablator to support higher implosion pressures.   Read the full story at: https://lnkd.in/gy6cCwE4 Note: a few participants in these experiments benefited from the financial support of the @European Union COST Action PROBONO (PROton BOron Nuclear fusion: from energy production to medical applications). #fusion #fusionenergy #renewableenergy #cleanenergy #sustainableenergy

Physics News: Toroidal Dipole Excitations Observed in Nickel-58 Nucleus Researchers have observed evidence of elusive toroidal dipole excitations in the nucleus of Nickel-58 (58Ni), a phenomenon long theorized but difficult to detect. These excitations involve unique toroidal (doughnut-shaped) distributions of currents that create vortex-like structures, resembling smoke rings. This discovery, detailed in Physical Review Letters, is a significant step in the study of nuclear physics and related fields. What Are Toroidal Dipole Modes? • Vortex-Like Currents: Toroidal dipole excitations are characterized by currents flowing in a toroidal (ring-shaped) pattern, forming vortex-like structures. • Cross-Disciplinary Phenomenon: These modes are predicted in various systems, including atomic nuclei, solid-state physics, metamaterials, and heavy-ion collisions, making their observation highly relevant across multiple scientific disciplines. Breakthrough Discovery in Nickel-58 • First Evidence in Nuclei: The researchers, from Technische Universität Darmstadt and the Joint Institute for Nuclear Research, identified potential candidates for toroidal dipole excitations in 58Ni, marking the first such observation in atomic nuclei. • Experimental Insights: Using advanced spectroscopy techniques, the team detected specific energy levels and current distributions consistent with the theoretical predictions of toroidal dipole modes. Significance of the Findings • Advancing Nuclear Physics: This breakthrough confirms a decades-old theoretical prediction and opens new avenues for studying exotic excitation modes in heavy nuclei. • Cross-Field Implications: Toroidal flows, common in other areas like solid-state physics and photonics, can now be explored further within the framework of nuclear systems, enabling new experiments and applications. What’s Next? The discovery of toroidal dipole excitations in Nickel-58 is expected to inspire further research into these modes in other nuclei and physical systems. Future studies may delve deeper into the dynamics of these vortex-like currents, potentially revealing novel quantum properties and broadening our understanding of nuclear and condensed matter physics.

Ion Implantation into Nonconventional GaN Structures | Review by Katharina Lorenz https://lnkd.in/g6kgnfqb ULisboa; INESC；MDPI #group III nitrides; #non-polar #GaN; #nanowires; #ion #implantation; #doping #physics This article belongs to the Special Issue: Selected Papers from Applied Nuclear Physics Conference 2021 https://lnkd.in/ghJdaRhH #Abstract Despite more than two decades of intensive research, ion implantation in group III nitrides is still not established as a routine technique for doping and device processing. The main challenges to overcome are the complex defect accumulation processes, as well as the high post-implant annealing temperatures necessary for efficient dopant activation. This review summarises the contents of a plenary talk, given at the Applied Nuclear Physics Conference, Prague, 2021, and focuses on recent results, obtained at Instituto Superior Técnico (Lisbon, Portugal), on ion implantation into non-conventional GaN structures, such as non-polar thin films and nanowires. Interestingly, the damage accumulation is strongly influenced by the surface orientation of the samples, as well as their dimensionality. In particular, basal stacking faults are the dominant implantation defects in c-plane GaN films, while dislocation loops predominate in a-plane samples. Ion implantation into GaN nanowires, on the other hand, causes a much smaller density of extended defects compared to thin films. Finally, recent breakthroughs concerning dopant activation are briefly reviewed, focussing on optical doping with europium and electrical doping with magnesium.
