Tokamaks

, 2005
Publisher Summary A team of British scientists was invited to go to Moscow the following year to measure the temperature with a new technique based on lasers. When these results were published, even the most skeptical fusion researchers were convinced. Thereafter tokamaks set the pace for magnetic-confinement fusion research.

Inferring the scrape-off layer heat flux width in a divertor with a low degree of axisymmetry

Nuclear Materials and Energy
Plasma facing components (PFCs) in the next generation of tokamak devices will operate in challenging environments, with heat loads predicted to exceed 10 MW/m2. The magnitude of these heat loads is set by the width of the channel, the ‘scrape-off layer’

Distinct turbulence saturation regimes in stellarators [PDF]

, 2017
In the complex 3D magnetic fields of stellarators, ion-temperature-gradient turbulence is shown to have two distinct saturation regimes, as revealed by petascale numerical simulations, and explained by a simple turbulence theory.

Presentation of the new SOLPS-ITER code package for tokamak plasma edge modelling

, 2016
We present in this paper the code package SOLPS-ITER, initially introduced by S. Wiesen et al. [J. Nucl. Mater. 463, 480 (2015)], dedicated to simulations of plasmas in the edge region of fusion devices.

Development of a Set of Synthetic Diagnostics for the Confrontation between 2D Transport Simulations and WEST Tokamak Experimental Data

Applied Sciences, 2022
Transport codes are frequently used for describing fusion plasmas with the aim to prepare tokamak operations. Considering novel codes, such as SolEdge3X-HDG, synthetic diagnostics are a common technique used to validate new models and confront them with ...

Neutral beam driven ion cyclotron instability of lower hybrid wave in a tokamak plasma

AIP Advances, 2022
The effect of dust grains on the parametric coupling of neutral beam driven ion–cyclotron wave instability with a lower hybrid pump wave is studied. A high amplitude lower hybrid pump, which is launched into a tokamak for heating purposes in the presence

Quantum Iterative Methods for Solving Differential Equations with Application to Computational Fluid Dynamics

Advanced Quantum Technologies, EarlyView.
Quantum algorithms for differential equations are developed with applications in computational fluid dynamics. The methods follow an iterative simulation framework, implementing Jacobi and Gauss–Seidel schemes on quantum registers through linear combinations of unitaries.

Superconducting Magnet Technology and Magnetically Confined Fusion

南方能源建设, 2022
[Introduction] Magnetically confined fusion is an effective way to solve the energy problem. To direct to quasi-steady state discharges and their relevant physics, the superconducting magnet (especially the high field HTS magnet) had become the first ...
