"Symmetry-broken self-interstitial defects in chromium, molybdenum and tungsten"

• Pui-Wai Ma
• S. L. Dudarev

For several decades, the striking contradiction between the Huang diffuse scattering experiments, resistivity recovery data, and predictions derived from density functional theory (DFT) remained one of the mysteries of defect physics in molybdenum. Since the nineteen seventies, observations of Huang X-ray diffuse scattering appeared to indicate …

During edge localised modes (ELMs) high heat fluxes are incident on divertor targets, which future fusion devices will not withstand [1]. A solution to reduce the heat fluxes could be the new Super-X divertor, which will be tested on the MAST-U tokamak. The divertor has an increased connection length, magnetic flux expansion and is designed to reta…

The presence of Error Fields (EFs) in magnetic fusion devices can affect energy confinement and plasma stability by braking plasma rotation, by inducing fast particle losses and being amplified when exploring high-b regimes. The resulting EF Locked Modes (LMs) can be stabilized by NBI injection through the rotation shielding mechanism. However, …

"DEMO First Wall misalignment study by 3D field line tracing"

Within the framework of EUROfusion DEMO First Wall and limiter design activities, the protection of the First Wall against power deposition peaks is being considered. During steady-state operation, the radiative power from the plasma could be considered uniformly spread on plasma-facing components. However, the presence of openings (i.e. g…

An understanding of the plasma edge and divertor is essential for predicting the performance of next-step machines such as ITER. Transport codes used to study the divertor behaviour [1] employ atomic physics data in two applications. The first is to predict the power radiated by the fuel and impurity atoms, which is carried out as a post-processing…

"Building Trust in Automated Vehicles – The Role of Fenced Test Sites"

• Garry Staunton

One of the primary benefits from automated/autonomous vehicles (AV) is the promise of increased road safety through reductions in the number of driver error-induced accidents, where an often-cited statistic is that around 90% of all motor vehicle crashes are caused by human error. The flip-side of this is that one of the greatest barriers to the wi…

"Could Connected and Autonomous Vehicles Transform Asset Inspection?"

• David J Trousdale
• Garry M Staunton

Whilst Connected and Autonomous Vehicles (CAV) hold the promise of relegating the driver to passenger by transforming vehicles into intelligent platforms able to ‘read’ and ‘sense’ their environment. A corollary of this is that not only will these vehicles transform how people get from A-to-B, they will be a major source of information whic…
