Dynamics of scrape-off layer filaments in detached conditions
David Schwörer, Nick R. Walkden, Benjamin D. Dudson +3
The here presented work studies the dynamics of filaments using 3D fluid simulations in the presence of detached background profiles. It was found that evolving the neutrals on the…
Fast modeling of turbulent transport in fusion plasmas using neural networks
Karel Lucas van de Plassche, Jonathan Citrin, Clarisse Bourdelle +7
We present an ultrafast neural network (NN) model, QLKNN, which predicts core tokamak transport heat and particle fluxes. QLKNN is a surrogate model based on a database of 300 mill…
Stabilisation of short-wavelength instabilities by parallel-to-the-field shear in long-wavelength flows
M. R. Hardman, M. Barnes, C. M. Roach
Magnetised plasma turbulence can have a multiscale character: instabilities driven by mean temperature gradients drive turbulence at the disparate scales of the ion and the electro…
Increasing the accuracy of laser flash analysis using numerical algorithms robust to noise and systematic errors
Artem Lunev, Robert Heymer
The laser flash method is highly regarded due to its applicability to a wide temperature range, from cryogenic temperatures to the melting point of refractory metals, and to extrem…
Classification of chaotic time series with deep learning
Nicolas Boullé, Vassilios Dallas, Yuji Nakatsukasa +1
We use standard deep neural networks to classify univariate time series generated by discrete and continuous dynamical systems based on their chaotic or non-chaotic behaviour. Our…
Dependence on ion temperature of shallow-angle magnetic presheaths with adiabatic electrons
Alessandro Geraldini, Felix I Parra, Fulvio Militello
The magnetic presheath is a boundary layer occurring when magnetized plasma is in contact with a wall and the angle between the wall and the magnetic field is oblique…
