Reducing Turbulent Transport in Tokamaks by Combining Intrinsic Rotation and the Low Momentum Diffusivity Regime

Stephan Brunner, Justin Richard Ball, Haomin Sun

Based on the analysis of a large number of high-fidelity nonlinear gyrokinetic simulations, we propose a novel strategy to improve confinement in spherical tokamak plasmas by combining up-down asymmetric flux surface shaping with the Low Momentum Diffusivi ...

Investigation of triangularity effects on tokamak edge turbulence through multi-fidelity gyrokinetic simulations

Paolo Ricci, Antoine Cyril David Hoffmann, Alessandro Balestri

This paper uses the gyro-moment (GM) approach as a multi-fidelity tool to explore the effect of triangularity on tokamak edge turbulence. Considering experimental data from an L-mode DIII-D discharge, we conduct gyrokinetic (GK) simulations with realistic ...

Structure and Magnetic Properties of a Series of Uranium Bis-Siloxide Complexes

Marinella Mazzanti, Ivica Zivkovic, Farzaneh Fadaei Tirani, Luciano Barluzzi

Despite their synthetic interest and potential attractive properties, the preparation of heteroleptic U(III) complexes containing monodentate ligands remains challenging. Here we report the synthesis, structure and magnetic properties of three heteroleptic ...

Overview of T and D-T results in JET with ITER-like wall

Olivier Sauter, Holger Reimerdes, Duccio Testa, Benoît Labit, Umar Sheikh, Olivier Claude Martin Février, Eduardo José Lascas Neto, Cristian Sommariva, Alessandro Pau, Matteo Vallar, Gino Marceca, Cassandre Ekta Contré, Mackenzie Peter-Fulford Van Rossem, Samuele Mazzi, Carl Mathias Paul Hoppe

In 2021 JET exploited its unique capabilities to operate with T and D-T fuel with an ITER-like Be/W wall (JET-ILW). This second major JET D-T campaign (DTE2), after DTE1 in 1997, represented the culmination of a series of JET enhancements-new fusion diagno ...

Electronic excitations and spin interactions in chromium trihalides from embedded many-body wavefunctions

Oleg Yazyev, Ravi Yadav

Although chromium trihalides are widely regarded as a promising class of two-dimensional magnets for next-generation devices, an accurate description of their electronic structure and magnetic interactions has proven challenging to achieve. Here, we quanti ...

Cosmic evolution of the Faraday rotation measure in the intracluster medium of galaxy clusters

Yoan Rappaz, Salim Bennouna, Abhijit Bhausaheb Bendre

Context. Radio observations have revealed magnetic fields in the intracluster medium (ICM) of galaxy clusters, and their energy density is nearly in equipartition with the turbulent kinetic energy. This suggests magnetic field amplification by dynamo proce ...

Compact fusion blanket using plasma facing liquid Li-LiH walls and Pb pebbles

Sabine Elodie Ogier-Collin

Liquid plasma facing walls allow for increased neutron-wall loading expanding the design space of fusion power-plants and experimental devices towards compact high-field reactors. This study presents the design of a compact radial build blanket for fusion ...

An asymptotic-preserving semi-Lagrangian algorithm for the anisotropic heat transport equation with arbitrary magnetic fields

Giovanni Di Giannatale

We extend the recently proposed semi-Lagrangian algorithm for the extremely anisotropic heat transport equation [Chacón et al., J. Comput. Phys., 272 (2014)] to deal with arbitrary magnetic field topologies. The original scheme (which showed remarkable num ...

Kinetic plasma-wall interaction using immersed boundary conditions

Emily Louise Bourne

The interaction between a plasma and a solid surface is studied in a (1D-1V) kinetic approach using immersed boundary conditions and penalization to model the wall. Two solutions for the penalized wall region are investigated that either allow currents to ...

Time warping between main epidemic time series in epidemiological surveillance

Jean-David Horacio Morel

The most common reported epidemic time series in epidemiological surveillance are the daily or weekly incidence of new cases, the hospital admission count, the ICU admission count, and the death toll, which played such a prominent role in the struggle to m ...

Source identification via contact tracing in the presence of asymptomatic patients

Patrick Thiran, Gergely Odor, Miguel-Angel Sanchez Ndoye

Inferring the source of a diffusion in a large network of agents is a difficult but feasible task, if a few agents act as sensors revealing the time at which they got hit by the diffusion. One of the main limitations of current source identification algori ...

Aircraft Departures Management for Low Altitude Air City Transport based on Macroscopic Fundamental Diagram

Nikolaos Geroliminis

Low-altitude aircraft is being developed as a new mode of urban transport. This will give rise to new urban air transport systems, called low-altitude air city transport (LAAT) systems. Recent works show that the Macroscopic Fundamental Diagram (MFD) is a ...

64-kB 65-nm GC-eDRAM With Half-Select Support and Parallel Refresh Technique

Andreas Peter Burg, Robert Giterman, Emmanuel Nieto Casarrubias

Gain-cell-embedded DRAM (GC-eDRAM) is an attractive alternative to traditional 6T SRAM, as it offers higher density, lower leakage power, and two-ported functionality. However, its refresh requirement also results in power consumption and memory access lim ...
