The European research consortium EUROfusion has had more than 100 fusion facilities in its member states independently assessed. The facilities of the Max Planck Institute for Plasma Physics (IPP) were consistently categorised in the best ‘Indispensable’ category. How important are the European nuclear fusion research facilities on the way to a fusion power plant? An independent panel of experts investigated this question on behalf of the European consortium EUROfusion. Between autumn 2023 and spring 2024, the panel evaluated more than 100 facilities. It consisted of five EU experts who are not involved in fusion research and six fusion experts who work for organisations outside the EU. In their final report ‘EUROfusion Facilities Review 2023’, the experts recognised the leading role of European fusion research in several areas. The experts categorised the existing research facilities according to their importance as ‘Indispensable’, ‘Very Important’ and ‘Important’. The panel categorised the four IPP facilities examined in the best category. ‘Indispensable’ are therefore  • ASDEX Upgrade – The experts describe the IPP facility as the current ‘flagship facility’ of the EUROfusion Tokamak programme. • Wendelstein 7-X – the largest and most powerful stellarator in the world. • GLADIS – according to the panel an indispensable high heat flux test facility for ITER and DEMO divertor and first wall components.  • BATMAN Upgrade and ELISE – “unique test facilites for negative-Ion Neutral Beam Injection (NNBI) sources, embedded in the size scaling route for ITER NNBI.” Photos: MPI für Plasmaphysik / Jan Hosan (2), Frank Fleschner, Volker Rohde #nuclearfusion #fusionenergy

In many ways, a fusion reactor is passively safe; most off-normal events within such a device produce a naturally occurring behavior that leads to the calm shutdown of the fusion reaction without operator intervention. One outlier off-normal event is the formation of a relativistic electron beam, which is a very high-energy electron beam capable of causing significant damage to reactor walls. A concept to passively disperse these high-energy electrons before they build up a large beam is to perturb their orbits by applying a magnetic field. To make this response passive, a conducting coil can be installed inside the reactor. Without any power supply connection, this coil is energized by the initial relativistic electrons during early formation of the beam. The resulting magnetic field then disturbs the electron orbits, causing them to be lost before the beam reaches appreciable energy levels. In this newly published work from Alexander Battey and colleagues, they unveil a new modeling tool for designing these coils. Taking into account the vacuum vessel of the device, the appropriate positioning and winding path of the coil can be determined. Furthermore, the expected effect on relativistic electron beams is simulated, ensuring that the optimum coil has been designed. Over the next few years, we will see these coils installed in both the DIII-D tokamak and the SPARC tokamak of Commonwealth Fusion Systems. Experimental demonstration in research devices is an important step to designing a Fusion Pilot Plant and the reactors that follow. This work was led by Columbia University with co-authors from the Plasma Science and Fusion Center at MIT, General Atomics, and Commonwealth Fusion Systems. A.F.

A new MITEI-funded study is advancing technologies required for fusion energy. The neutrons in fusion reactors are much more kinetic than in fission reactors, meaning these neutrons can react with the atomic structure of the reactor itself. Led by Professor Ju Li, MIT engineers have found a way to address this problem by making the structural materials last longer under the harsh conditions inside a fusion reactor.

MeanField4Exp, a Virtual Access Facility (a part of the Theo4Exp initiative in the EURO-LABS project), was recently opened for the users. It can be access via meanfield4exp.ifj.edu.pl and by login using the ORCID or eduGAIN. This website is based on an extensive research program developed over many years by J. Dudek (IPHC and University of Strasbourg) and his collaborators from IFJ PAN Krakow; it allows to explore elementary structure properties of atomic nuclei, including shapes, symmetries and excitations, using Realistic Phenomenological Nuclear Mean Field Theory Calculations. The services in this website are focused on providing numerical results which are organised in suitable formats to maximise the efficient transfer of theoretical information to experimentalists, principally associated with research projects at the European nuclear accelerator centres. Our theory services are expected to be especially helpful in the interpretation of existing experimental data and the development of new experimental proposals at these major facilities. The theoretical diagrams and other forms of results discussed here, such as single-particle energy diagrams, potential energy surfaces showing the shape evolution and coexistence in nuclei, and many other options, have become de-facto standards in the field, and are easy to follow and apply.
