Global 'zero particle flux-driven' gyrokinetic analysis of the density profile for a TCV plasma

Olivier Sauter, Stephan Brunner, Gabriele Merlo, Alberto Mariani

The tokamak `a configuration variable (TCV) is a small-sized tokamak, where finite size effects (often called 'rho-star' or 'global' effects) could significantly impact the heat and particle fluxes, leading to discrepancies between gyrokinetic flux-tube re ...

The Alfvenic nature of chromospheric swirls

Aleksi Antoine Bossart, Andrea Francesco Battaglia

Context. Observations show that small-scale vortical plasma motions are ubiquitous in the quiet solar atmosphere. They have received increasing attention in recent years because they are a viable candidate mechanism for the heating of the outer solar atmos ...

A Disk Asymmetry in Motion Around the B[e] Star MWC158

Ferréol Arnaud Marie Soulez

Context. MWC158 is a star with the B[e] phenomenon that shows strong spectrophotometric variability (in lines and in UV and visible continuum) attributed to phases of shell ejection. The evolutionary stage of this star was never clearly determined. Previou ...

Rayleigh-Taylor instability under an inclined plane

François Gallaire, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun, Pierre Rieu

We revisit the canonical Rayleigh-Taylor instability and investigate the case of a thin film of fluid upon the underside of an inclined plane. The presence of a natural flow along the plane competes with the conventional droplet forming instability. In par ...

Communication-based Leashing of Real Flying Robots

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert, Severin Leven

Aerial robots are often required to remain within the communication range of a base station on the ground to exchange commands, sensor data or as a safety mechanism. For this purpose, we propose a minimal control strategy for steering flying robots using o ...

Understanding sawtooth activity during intense electron cyclotron heating experiments on TCV

Timothy Goodman, Ivo Furno, Holger Reimerdes, Henri Weisen, Antoine Pochelon, Roland Behn

Different types of central relaxation oscillations are observed in the presence of ECH depending on the location of the deposited power. In the TCV tokamak, normal sawteeth, i.e. triangular sawteeth similar to ohmic sawteeth, and saturated sawteeth are obs ...
