Calibrated Adaptive Teacher for Domain-Adaptive Intelligent Fault Diagnosis

Olga Fink, Florent Evariste Forest

Intelligent fault diagnosis (IFD) based on deep learning can achieve high accuracy from raw condition monitoring signals. However, models usually perform well on the training distribution only, and experience severe performance drops when applied to a diff ...

Dissipative magnetic structures and scales in small-scale dynamos

Salim Bennouna

Small-scale dynamos play important roles in modern astrophysics, especially on galactic and extragalactic scales. Owing to dynamo action, purely hydrodynamic Kolmogorov turbulence hardly exists and is often replaced by hydromagnetic turbulence. Understandi ...

Validation of 2D T e and n e measurements made with Helium imaging spectroscopy in the volume of the TCV divertor

Basil Duval, Patrick Blanchard, Holger Reimerdes, Christian Gabriel Theiler, Cedric Kar-Wai Tsui, Artur Perek, Hugo De Oliveira, Filippo Bagnato, Lorenzo Martinelli, Sophie Danielle Angelica Gorno, Claudia Colandrea, Nicola Offeddu, Dmytry Mykytchuk

Multi-spectral imaging of helium atomic emission (HeMSI) has been used to create 2D poloidal maps of T-e and ne in TCV's divertor. To achieve these measurements, TCV's MANTIS multispectral cameras (Perek et al 2019 Rev. Sci. Instrum. 90 123514) simultaneou ...

Chiral magnetohydrodynamics with zero total chirality

Salim Bennouna

We study the evolution of magnetic fields coupled with chiral fermion asymmetry in the framework of chiral magnetohydrodynamics with zero initial total chirality. The initial magnetic field has a turbulent spectrum peaking at a certain characteristic scale ...

Surface DBD degradation in humid air, and a hybrid surface-volume DBD for robust plasma operation at high humidity

Ivo Furno, Alan Howling, Fabio Avino, Alexandra Waskow, Lorenzo Ibba, Jia Han

Surface dielectric barrier discharge performance deteriorates in humid air, with permanent and/or reversible degradation of its components. Plasma operation in a humid environment is unavoidable when humid air or water-containing materials are treated. Exp ...

Fast ion generation with ICRF waves and beams in the Wendelstein 7-X stellarator

Mike Machielsen

The largest operating stellarator, Wendelstein 7-X, is of the quasi-isodynamic type. For this design to scale up to a fusion reactor, several criteria must be met, one of them being good fast ion confinement. The latter still has to be tested experimentall ...

Conceptual study for velocity space resolved thermal ion loss detection in tokamaks

Jesús Poley Sanjuán

A new concept for velocity space thermal ion loss detection is presented. This diagnostic provides pitch angle resolved measurements that are unfeasible with current diagnostics. It uses the same detection principle as the Fast-Ion Loss Detector with a sci ...
