Preliminary design of the ITER ECH Upper Launcher

Olivier Sauter, Timothy Goodman, René Chavan, Jean-Daniel Landis, Francisco Sanchez, Hartmut Zohm, Emanuele Poli

The design of the ITER electron cyclotron launchers recently reached the preliminary design level - the last major milestone before design finalization. The ITER ECH system contains 24 installed gyrotrons providing a maximum ECH injected power of 20 MW thr ...

Thinking Penguin: Multi-modal Brain-Computer Interface Control of a VR Game

Robert Leeb

We describe a multi-modal brain-computer interface (BCI) experiment, situated in a highly immersive CAVE. A subject sitting in the virtual environment controls the main character of a virtual reality game: a penguin that slides down a snowy mountain slope. ...

Quotient method for stabilising a ball-on-a-wheel system – Experimental results

Dominique Bonvin, Philippe Müllhaupt, Killian Mark Daly

This paper extends the quotient method proposed in [1] and applies it to stabilize a “ball-on-a-wheel” system. The quotient method requires a diffeomorphism to obtain the normal form of the input vector field and uses canonical pro- jection to obtain the q ...

Joint Detection and Localization of Multiple Speakers using a Probabilistic Interpretation of the Steered Response Power

Detection and localization of multiple speakers in a noisy and reverberant environment is a fundamental and difficult task. In the literature, steered response power (SRP) based techniques are typically used to accomplish this task which can be computation ...

Modelling and stability analysis of the 155 mm spin-stabilised projectile equipped with steering fins

Yannick Morel

The presented work concerns the modelling and stability analysis of 155 mm spin-stabilised projectiles equipped with steering fins. While a large roll rate provides the projectile with interesting stability properties, it also renders the steering control ...

Progress on the ITER H&D EC Upper Launcher Steering-Mirror Control System

Timothy Goodman, René Chavan, Federico Alberto Alfredo Felici, Jean-Daniel Landis, Frédéric Dolizy, Francisco Sanchez, Robert Bertizzolo

The ITER Heating and Current Drive Upper Launcher (H&CD EC UL) uses a pneumomechanical steering-mirror assembly (SMA) to steer the RF beams for their deposition in the appropriate location in the plasma to control magnetohydrodynamic activity (neoclassical ...

Insect Vision: A Few Tricks to Regulate Flight Altitude

Dario Floreano, Jean-Christophe Zufferey

A recent study sheds new light on the visual cues used by Drosophila to regulate flight altitude. The striking similarity with previously identified steering mechanisms provides a coherent basis for novel models of vision-based flight control in insects an ...

Flexure-based pointing mechanism with sub-microradian resolution for the Laser Interferometer Space Antenna

Simon Nessim Henein, Philippe Schwab

The Point Ahead Angle Mechanism (PAAM) for ESA’s Laser Interferometer Space Antenna (LISA) mission will compensate the out-of-plane point-ahead angle between three satellites flying 5 million kilometres apart. The PAAM consists of a mirror supported by fle ...

Finalization of the conceptual design of the remote steering ECH launcher for ITER

René Chavan

The design of a remote steering (RS) variant of the electron cyclotron heating (ECH) upper port launcher (UPL) for neo-classical tearing mode (NTM) stabilization in ITER is being finalised. The RS variant is the fall-back option for the reference design, w ...
