Simultaneous measurements of unstable and stable Alfven eigenmodes in JET
Ambrogio Fasoli, Mario Ludovico Podesta
In this paper, we report the novel experimental observation of both unstable and stable toroidicity-induced Alfven eigenmodes (TAEs) measured simultaneously in a JET tokamak plasma. The three-ion-heating scheme (D-DNBI-He-3) is employed to accelerate deute ...
IOP Publishing Ltd2022The high-power helicon program at DIII-D: gearing up for first experiments
Helicon current drive (CD), also called fast wave CD in the lower hybrid range of frequencies, has long been regarded as a promising CD tool for reactor grade plasmas. A newly installed MW-level system at DIII-D will be the first test of this technology in ...
IOP Publishing Ltd2021Operational-Driven Optimal-Design of a Hyperloop System
We present an operational-driven optimal-design framework of a Hyperloop system. The novelty of the proposed framework is in the problem formulation that links the operation of a network of Hyperloop capsules, the model of the Hyperloop infrastructure, and ...
2021Wireless Electrohydrodynamic Actuators for Propulsion and Positioning of Miniaturized Floating Robots
Autonomous soft robots require compact actuators generating large strokes and high forces. Electro-fluidic actuators are especially promising, they combine the advantages of electroactive polymers (low-power consumption, fast response, and electrical power ...
WILEY2021Helicon wave plasma generated by a resonant birdcage antenna: magnetic field measurements and analysis in the RAID linear device
Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne, Rémy Jacquier, Riccardo Agnello
This paper describes a helicon-wave-sustained plasma generated by a novel birdcage antenna with cosine azimuthal current distribution. The resonant birdcage source maintains a stable intense plasma column from low (300 W) to high (10 kW) steady-state RF po ...

This work presents a quantitative test of SOLPS-ITER simulations against tokamak a configuration variable (TCV) L-mode experiments. These simulations account for drifts, currents, kinetic neutrals, and carbon impurities providing the most complete edge tra ...
AMER INST PHYSICS2021Propulsion and energetics of a minimal magnetic microswimmer
In this manuscript we describe the realization of a minimal hybrid microswimmer, composed of a ferromagnetic nanorod and a paramagnetic microsphere. The unbounded pair is propelled in water upon application of a swinging magnetic field that induces a perio ...
ROYAL SOC CHEMISTRY2020Influence of Battery Models on the Optimal Design of the Propulsion System of a Hyperloop Capsule
The paper assesses the influence of equivalent circuit battery models on the optimal design of the propulsion system of an energy-autonomous Hyperloop capsule. By knowing a pre-determined payload to be transported along pre-determined trajectories, the pro ...
IEEE2020Design and development of the efficient anguilliform swimming robot- MAR
Auke Ijspeert, Peter Eckert, Anouk Looijestijn
Propulsion of swimming robots at the surface and underwater is largely dominated by rotary propellers due to high thrust, but at the cost of low efficiency. Due to their inherently high speed turning motion, sharp propeller blades and generated noise, they ...
IOP PUBLISHING LTD2020Buckling instabilities and spatio-temporal dynamics of active elastic filaments
Biological filaments driven by molecular motors tend to experience tangential propulsive forces also known as active follower forces. When such a filament encounters an obstacle, it deforms, which reorients its follower forces and alters its entire motion. ...
