The structure of 3-D collisional magnetized bow shocks in pulsed-power-driven plasma flows
(Cambridge University Press, 2022-12)We investigate 3D bow shocks in a highly collisional magnetized aluminum plasma, generated during the ablation phase of an exploding wire array on the MAGPIE facility (1.4 MA, 240 ns). Ablation of plasma from the wire array ... -
Data augmentation for disruption prediction via robust surrogate models
(Cambridge University Press, 2022-05)The goal of this work is to generate large statistically representative datasets to train machine learning models for disruption prediction provided by data from few existing discharges. Such a comprehensive training ... -
Towards Fast and Accurate Predictions of Radio Frequency Power Deposition and Current Profile via Data-driven Modeling
(Cambridge University Press, 2022-04)Three machine learning techniques (multilayer perceptron, random forest, and Gaussian process) provide fast surrogate models for lower hybrid current drive (LHCD) simulations. A single GENRAY/CQL3D simulation without radial ...
