Utilizing parametric instabilities to diagnose edge density fluctuations in TCV

Two-plasmon decay instabilities (TPDIs) are a class of parametric instabilities where a gyrotron beam, polarized in X-mode, decays nonlinearly into two upper hybrid waves at approximately half frequency. Here, we present the design of a simple radiometer t ...

Plasma profile reconstruction supported by kinetic modeling

Pedro Andres Molina Cabrera

Combining the analysis of multiple diagnostics and well-chosen prior information in the framework of Bayesian probability theory, the Integrated Data Analysis code (IDA Fischer et al 2010 Fusion Sci. Technol. 58 675-84) can provide density and temperature ...

Experimental characterization of the TCV dual-frequency gyrotron and validation of numerical codes including the effect of After Cavity Interaction

Timothy Goodman, Stefano Alberti, Jean-Philippe Hogge, Damien Fasel, Jérémy Genoud, Ugo Siravo, Jérémie Dubray, Matthieu Toussaint, Falk Hans Braunmüller, François Jean Gaston Legrand

A dual-frequency gyrotron has been developed within the context of the recent Tokamak à Configuration Variable (TCV) upgrade. The gyrotron is designed to generate a 1 MW, 2 seconds RF wave at 84 or 126 GHz. Before integrating the gyrotrons in the TCV tokam ...

An interpretable isoflux-based observer for plasma shape control errors in tokamaks

Stefano Coda, Federico Alberto Alfredo Felici, Antoine Pierre Emmanuel Alexis Merle, Adriano Mele

In tokamaks, plasma shape control is often achieved through a so-called isoflux approach that regulates the poloidal flux differences between a reference point and a set of control points and magnetic field values at suitable locations to obtain the desire ...

Representation learning algorithms for inferring machine independent latent features in pedestals in JET and AUG

Yoeri Renier Johannes Poels

Variational autoencoder (VAE)-based representation learning algorithms are explored for their capability to disentangle tokamak size dependence from other dependencies in a dataset of thousands of observed pedestal electron density and temperature profiles ...

Highlights of recent SPIDER results and improvements

Riccardo Agnello, Basile Marie Jacques Pouradier Duteil

Three years of experiments on SPIDER allowed characterization of the main features of the source plasma and of the negative ion beam, in the original design configuration. For the large dimensions of the source chamber, and of the extraction area, the inve ...

A splitting method for the numerical simulation of free surface flows with sediment deposition and resuspension

Marco Picasso, Arwa Mrad

We present a numerical model for the simulation of 3D sediment transport in a Newtonian flow with free surfaces. The Navier-Stokes equations are coupled with the transport, deposition, and resuspension of the particle concentrations, and a volume-of-fluid ...

A Kirchhoff-like theory for hard magnetic rods under geometrically nonlinear deformation in three dimensions

Pedro Miguel Nunes Pereira de Almeida Reis, Matteo Pezzulla

Magneto-rheological elastomers (MREs) are functional materials that can be actuated by applying an external magnetic field. MREs comprise a composite of hard magnetic particles dispersed into a nonmagnetic elastomeric (soft) matrix. Hard MREs have been rec ...

Mott versus Hybridization Gap in the Low-Temperature Phase of 1T-TaS2

Oleg Yazyev, Diego José Pasquier

We address the long-standing problem of the ground state of 1T-TaS2 by computing the correlated electronic structure of stacked bilayers using the GW + EDMFT method. Depending on the surface termination, the semi-infinite uncorrelated system is either band ...

Bootstrapping the a-anomaly in 4d QFTs

João Miguel Augusto Penedones Fernandes, Biswajit Sahoo, Jan Krzysztof Marucha

We study gapped 4d quantum field theories (QFTs) obtained from a relevant deformation of a UV conformal field theory (CFT). For simplicity, we assume the existence of a Z(2) symmetry and a single Z2-odd stable particle and no Z(2)-even particles at low ene ...
