Observation of lobes near the X-point in resonant magnetic perturbation experiments on MAST

, 2012
The application of non-axisymmetric resonant magnetic perturbations (RMPs) with a toroidal mode number n=6 in the MAST tokamak produces a significant reduction in plasma energy loss associated with type-I Edge Localized Modes (ELMs), the first such ...

Time-dependent full-radius integrated modeling of the DTT tokamak main plasma scenarios

Nuclear Fusion
We use an integrated modeling workflow with the transport code ASTRA coupled with the quasi-linear transport model TGLF-SAT2, the neoclassical model NCLASS, the FACIT model for the neoclassical impurity transport and the IMEP routines for the pedestal ...

Drift-Kinetic Modeling of Particle Acceleration and Transport in Solar Flares

, 2010
Based on the drift-kinetic theory, we develop a model for particle acceleration and transport in solar flares. The model describes the evolution of the particle distribution function by means of a numerical simulation of the drift-kinetic Vlasov equation,

May 12 1997 Cme Event: I. a Simplified Model of the Pre-Eruptive Magnetic Structure

, 2007
A simple model of the coronal magnetic field prior to the CME eruption on May 12 1997 is developed. First, the magnetic field is constructed by superimposing a large-scale background field and a localized bipolar field to model the active region (AR) in ...

Impact of spatially varying transport coefficients in EMC3-Eirene simulations of W7-X and assessment of drifts

Nuclear Fusion
Modelling the scrape-off layer of a stellarator is challenging due to the complex magnetic 3D geometry. The here presented study analyses simulations of the scrape-off layer (SOL) of the stellarator Wendelstein 7-X (W7-X) using spatially varying ...

Experiment-modeling studies comparing energy dissipation in the DIII-D SAS and SAS-VW divertors

Nuclear Materials and Energy
Recent DIII-D experiments on Small Angle Slot (SAS) divertors have confirmed that a combination of divertor closure and target shaping can enhance cooling across the divertor target and increase energy dissipation, but with significant dependence on BT ...

Testing magnetofrictional extrapolation with the Titov-D\'emoulin model of solar active regions

, 2010
We examine the nonlinear magnetofrictional extrapolation scheme using the solar active region model by Titov and D\'emoulin as test field. This model consists of an arched, line-tied current channel held in force-free equilibrium by the potential field ...

A Laser Beam Welding Process and Its Microstructural Thermoelastoplastic Analysis

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Laser beam welding has emerged as an advanced, contactless joining technique in recent years. This is primarily due to its high feed rates and low thermal distortion compared to conventional welding processes. These advantages stem from the focused energy input of the laser, enabling precise and controlled process execution.

Elongation of a Solar Filament and its Three-dimensional Numerical Reconstruction for Magnetic Structures

The Astrophysical Journal
Quiescent filaments are prominent features of the solar atmosphere, and their evolution reflects the coronal magnetic field’s response to photospheric magnetic activity.
