Re-design of EU DEMO with a low aspect ratio
The design point that had been chosen for EU DEMO in 2016 is reviewed here and a modification is proposed with a lower aspect ratio. Previously the same aspect ratio, A, was chosen for EU DEMO as in major tokamak experiments including ITER (A = 3.1), and, ...
2024A machine-learning-based tool for last closed-flux surface reconstruction on tokamaks
Olivier Sauter, Alessandro Pau, Xiaojuan Liu, Chenguang Wan
Tokamaks allow to confine fusion plasma with magnetic fields. The prediction/reconstruction of the last closed-flux surface (LCFS) is one of the primary challenges in the control of the magnetic configuration. The evolution in time of the LCFS is determine ...
IOP Publishing Ltd2023Maple leaf antiferromagnet in a magnetic field
Frédéric Mila, Pratyay Ghosh, Ronny Thomale
We analyze the quantum antiferromagnet on the maple leaf lattice in the presence of a magnetic field. Starting from its exact dimer ground state and for a magnetic field strength of the order of the local dimer spin-exchange coupling, we perform a strong-c ...
College Pk2023Perspective Aware Road Obstacle Detection
Pascal Fua, Mathieu Salzmann, Krzysztof Maciej Lis, Sina Honari
While road obstacle detection techniques have become increasingly effective, they typically ignore the fact that, in practice, the apparent size of the obstacles decreases as their distance to the vehicle increases. In this letter, we account for this by c ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Information-driven transitions in projections of underdamped dynamics
Daniel Maria Busiello, Giorgio Nicoletti, Amos Maritan
Low-dimensional representations of underdamped systems often provide useful insights and analytical tractability. Here, we build such representations via information projections, obtaining an optimal model that captures the most information on observed spa ...
AMER PHYSICAL SOC2022Fast Projection Onto Convex Smooth Constraints
Maryam Kamgarpour, Andreas Krause, Ilnura Usmanova
The Euclidean projection onto a convex set is an important problem that arises in numerous constrained optimization tasks. Unfortunately, in many cases, computing projections is computationally demanding. In this work, we focus on projection problems where ...
PMLR2021Joint Angular Refinement and Reconstruction for Single-Particle Cryo-EM
Michaël Unser, Laurène Donati, Emmanuel Emilien Louis Soubies, Mona Zehni
Single-particle cryo-electron microscopy (cryo-EM) reconstructs the three-dimensional (3D) structure of bio-molecules from a large set of 2D projection images with random and unknown orientations. A crucial step in the single-particle cryo-EM pipeline is 3 ...
2020Scale-invariant magnetic anisotropy in RuCl(3)at high magnetic fields
Philip Johannes Walter Moll, Maja Deborah Bachmann
Scale-invariant magnetic anisotropy in RuCl(3)has been revealed through measurements of its magnetotropic coefficient, providing evidence for a high degree of exchange frustration that favours the formation of a spin liquid state. In RuCl3, inelastic neutr ...
2020Side emissions during EC injection for PDI studies in FTU tokamak
Cristian Galperti, Gabriele Grosso
The evidence of Parametric Decay Instabilities (PDI) excited by the ECH power injected in O-Mode has been explored in FTU Tokamak, using the Collective Thomson Scattering (CTS) diagnostic. The experiments show evidences to support the hypothesis of low-thr ...
E D P SCIENCES2019MHD Stability and Energy Principle for Two-Dimensional Equilibria without Assumption of Nested Magnetic Surfaces
Laurent Villard, Andrei Martynov
Abandoning the assumption of nested magnetic surfaces in tokamak plasma expands the field of research and opens up new approaches for both theoretical and experimental plasma physics. The computer code KINX for calculations of the ideal MHD stability was d ...
