Polymer-based cantilevers with integrated electrodes

Jürgen Brugger, Giovanni Boero, Radivoje Popovic, Schahrazede-Lila Mouaziz

An innovative release method of polymer cantilevers with embedded integrated metal electrodes is presented. The fabrication is based on the lithographic patterning of the electrode layout on a wafer surface, covered by two layers of SU-8 polymer: a 10-um-t ...

A high current density DC magnetohydrodynamic (MHD) micropump

Nico de Rooij, Albert van den Berg

This paper describes the working principle of a DC magnetohydrodynamic (MHD) micropump that can be operated at high DC current densities (J) in 75-μm-deep microfluidic channels without introducing gas bubbles into the pumping channel. The main design featu ...

The new TAE - Alfvén Wave Active Excitation System at JET

Ambrogio Fasoli, Laurent Villard, Duccio Testa, René Chavan, Robert Bertizzolo

After many years of successful operation, the JET saddle coil system will be dismantled during the 2004-2005 shutdown. A new antenna system has been designed and is being constructed to replace it and excite magneto-hydrodynamics modes in the Alfvén freque ...

Synergy of CP-DGPS, Accelerometry and Magnetic Sensors for recise Trajectography in Ski Racing

Jan Skaloud

This paper presents the conceptual and technical aspects of a system in development that precisely determines athlete's trajectory through a course. Carrier phase-based (CP-DGPS) positioning represents core of the system, while tri-acial accelerometer and ...

Model for humpback relaxation oscillations

Olivier Sauter, Timothy Goodman, Ivo Furno, Holger Reimerdes, Antoine Pochelon, Roland Behn

An interpretation of non-standard, central MHD events in the TCV tokamak during localized ECRH is presented. It is shown that the non-standard behaviour is a consequence of specific features in the electron temperature profile produced when ECRH power is d ...

High-power ECH and fully non-inductive operation with ECCD in the TCV tokamak

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Yves Martin, Jean-Marc Moret, Stefano Alberti, Ivo Furno, Minh Quang Tran, Patrick Blanchard, Holger Reimerdes, Jean-Philippe Hogge, René Chavan, Damien Fasel, Xavier Llobet, Pierre Lavanchy, Henri Weisen, Jonathan Bryan Lister, Richard Pitts, Antoine Pochelon, Kurt Appert, Roland Behn, Philippe Marmillod, Gilbert Tonetti, Albert Perez, Blaise Marlétaz, Pierre-François Isoz, Jean-Claude Magnin, Andrei Martynov, Petri Nikkola, Adriano Manini, Paolo Bosshard, Edgar Scavino

Experiments with high-power electron cyclotron heating (ECH) and current drive (ECCD) in the TCV tokamak are discussed. Power up to 2.7 MW from six gyrotrons is delivered to the tokamak at the second-harmonic frequency (82.7 GHz) in X-mode. The power is tr ...

Anomaly inflow and RR anomalous couplings

Claudio Scrucca

We review the anomaly inflow mechanism on D-branes and O-planes. In particular, we compute the one-loop world-volume anomalies and derive the RR anomalous couplings required for their cancellation. ...

Resistive interchange modes in negative central shear tokamaks with peaked pressure profiles

Olivier Sauter

Resistive interchange modes can be driven unstable by large pressure gradients in the negative central magnetic shear (NCS) region of advanced tokamaks. Localized stability analysis reveals that the resistive interchange stability criterion (D-R less than ...
