Variability of MHD instabilities in benign termination of high-current runaway electron beams in the JET and DIII-D tokamaks

Benign termination, in which magnetohydrodynamic (MHD) instabilities deconfine runaway electrons (REs) following hydrogenic injections, is a promising strategy for mitigating dangerous RE loads after disruptions. Recent experiments on the Joint European Torus (JET) have explored this scenario at higher pre-disruptive plasma currents than are achievable on other devices, revealing challenges in obtaining benign terminations at I p ≥ 2.5 MA. This work analyzes the evolution of these high-current RE beams and

Power performance of a model floating wind turbine subjected to cyclic pitch motion: A wind tunnel study

Offshore floating wind turbines (OFWTs) are becoming increasingly popular due to their ability to exploit deep-sea wind resources. However, since wind turbines are installed on floaters instead of solid foundations, the dynamic response of an OFWT due to the wind-wave-structure coupled effects can bring structure safety concerns and affect the power performance. The dynamic response of an OFWT can be described by motions in six different degrees of freedom (DOFs) or directions, which are surge, sway, heave

Undo - Workshop at Future of Construction 2024

UNDO introduces an innovative workflow that leverages human-robot interaction (HRI) to facilitate dynamic and reconfigurable fabrication processes. Construction, like any act of making, can be unpredictable and require on-the-fly adjustments. Human-in-the-loop workflows combine human flexibility with robotic precision to overcome fabrication bottlenecks and increase on-site agility. This partnership between humans and robots is powerful, yet the interaction modalities and intervention protocols are still in

Cyclic Hypervalent Iodine Reagents for Azidation: Safer Reagents and Photoredox-Catalyzed Ring Expansion

Thierry Meyer, Jérôme Waser, Stefano Nicolai, Annik Nanchen, Raphaël Michel Henri Simonet-Davin, Sébastien Pierre Louis Alazet, Johannes Preindl

Azides are building blocks of increasing importance in synthetic chemistry, chemical biology, and materials science. Azidobenziodoxolone (ABX, Zhdankin reagent) is a valuable azide source, but its safety profile has not been thoroughly established. Herein, ...

Towards self-consistent plasma modelisation in presence of neoclassical tearing mode and sawteeth: effects on transport coefficients

Olivier Sauter, Antoine Pierre Emmanuel Alexis Merle

The neoclassical tearing modes (NTM) increase the effective heat and particle radial transport inside the plasma, leading to a flattening of the electron and ion temperature and density profiles at a given location depending on the safety factor q rational ...

A BVLOS UAV for Lake Surface Imagery

Ulrich Lemmin

We describe the development of a BVLOS (Beyond Visual Line-Of-Sight) model aircraft (UAV). The broad design requirements included: 1. BVLOS Legal authorization by the Swiss Federal Aviation authority 2. Suitable for land and water take-offs/landing 3. More than 60 minutes flight autonomy 4. Modularity of the imaging package 5. Real-time IR/RGB imagery Requirements 1 to 3 are driven by the goal of improving estimates of lake surface energy flux, since such fluxes have a major impact on long-term lake tempera
