Collisional-radiative data for tokamak disruption mitigation modeling
Prashant Sharma, Christopher J. Fontes, Dmitry V. Fursa +6
Effective tokamak disruption mitigation is crucial for ensuring the safety and integrity of fusion power reactors. Accurate collisional-radiative (CR) modeling of a radiative plasm…
Hybrid collisional-radiative modeling for high-fidelity atomic kinetics
Prashant Sharma, Christopher J. Fontes, Mark Zammit +3
The fidelity of collisional-radiative (CR) models is critical for advancing our understanding of radiative properties and ionization balance in fusion plasmas. In this work, we pre…
An iterative deep learning procedure for determining electron scattering cross-sections from transport coefficients
Dale L Muccignat, Gregory G Boyle, Nathan A Garland +2
We propose improvements to the Artificial Neural Network (ANN) method of determining electron scattering cross-sections from swarm data proposed by coauthors. A limitation inherent…
Semi-empirical analysis of leptons in gases in crossed electric and magnetic fields, Part II: Transverse compression of muon beams
Malte Hildebrandt, Robert E Robson, Nathan A Garland
This article employs fluid equations to analyse muon beams in gases subject to crossed electric and magnetic fields, focussing in particular on a scheme proposed by D. Taqqu in 200…
Efficient training of artificial neural network surrogates for a collisional-radiative model through adaptive parameter space sampling
Nathan A. Garland, Romit Maulik, Qi Tang +2
Reliable plasma transport modeling for magnetic confinement fusion depends on accurately resolving the ion charge state distribution and radiative power losses of the plasma. These…
Neural network representability of fully ionized plasma fluid model closures
Romit Maulik, Nathan A. Garland, Xian-Zhu Tang +1
The closure problem in fluid modeling is a well-known challenge to modelers aiming to accurately describe their system of interest. Over many years, analytic formulations in a wide…
Impact of a minority relativistic electron tail interacting with a thermal plasma containing high-atomic-number impurities
Nathan A. Garland, Hyun-Kyung Chung, Christopher J. Fontes +6
A minority relativistic electron component can arise in both laboratory and naturally-occurring plasmas. In the presence of high-atomic-number ion species, the ion charge state dis…
