On the accessibility of stable reactor operating regimes in quasi-symmetric stellarators
Adelle M. Wright, Benjamin J. Faber
Maximising particle and energy confinement is crucial for achieving the sustained burning plasma conditions necessary to realise fusion energy. For stellarator reactors, one propos…
Fast prediction of plasma instabilities with sparse-grid-accelerated optimized dynamic mode decomposition
Kevin Gill, Ionut-Gabriel Farcas, Silke Glas +1
Parametric data-driven reduced-order models (ROMs) that embed dependencies in a large number of input parameters are crucial for enabling many-query tasks in large-scale problems.…
On the effect of flux-surface shaping on trapped-electron modes in quasi-helically symmetric stellarators
M. J. Gerard, M. J. Pueschel, B. Geiger +5
Using a novel optimization procedure it has been shown that the Helically Symmetric eXperiment (HSX) stellarator can be optimized for reduced trapped-electron-mode (TEM) instabilit…
Walking on Spheres and Talking to Neighbors: Variance Reduction for Laplace's Equation
Michael Czekanski, Benjamin Faber, Margaret Fairborn +2
Walk on Spheres algorithms leverage properties of Brownian Motion to create Monte Carlo estimates of solutions to a class of elliptic partial differential equations. We propose a n…
Advancing technologies for high-resolution spatial and temporal measurements of macroscopic stellarator flows
A. M. Wright, D. J Den Hartog, B. Geiger +3
Stellarators, together with tokamaks, represent the two mainstream approaches to realizing fusion energy via toroidal magnetic confinement of highly ionized gases - plasmas - at ex…
Introduction to the Diffusion Monte Carlo Method
Ioan Kosztin, Byron Faber, Klaus Schulten
A self-contained and tutorial presentation of the diffusion Monte Carlo method for determining the ground state energy and wave function of quantum systems is provided. First, the…
