Central solenoid winding pack design for DEMO

Pierluigi Bruzzone, Kamil Sedlák, Davide Uglietti, Boris Stepanov, Rainer Wesche

The present study aims to reduce the outer radius of the central solenoid (CS) with respect to its nominal size specified by EUROfusion for a maintained CS magnetic flux. A reduced outer CS radius would allow the reduction of the overall size and cost of t ...

Stabilization of electrodynamic bearings with active magnetic dampers

Qingwen Cui

Electrodynamic Bearings (EDBs) are a kind of passive magnetic bearings that exploits the interaction between the induced eddy currents in a conductor and a magnetic field to provide re-storing forces. They have been regarded as an appealing alternative to ...

Modeling and evaluation of damping coefficient of eddy current dampers in rotordynamic applications

Eddy current dampers (ECD) can be used to introduce damping in rotordynamic applications. ECD5 are contactless in nature and can be made to introduce negligible drag force, thus being a perfect match for passive magnetic bearings such as permanent magnet b ...

Magnetic microrobots with addressable shape control

Mahmut Selman Sakar

Shape shifting soft microrobots are generated from self-folding hydrogel bilayer structures. The folding conditions are analyzed to develop an optimal strategy for producing desired three-dimensional shapes. We present two different methods for programming ...

Magnetic and Magnetoelectric Measurements on Ba2CoGe2O7

Thanh Phong Kevin Lê

Multiferroic materials show, in a single phase, at least two ferroic properties. The latter are are (anti-)ferroelectricity, (anti-)ferromagnetism or (anti-)ferroelasticity. Interesting applications can use the properties of multiferroics, especially with ...

Magnetic Hysteresis in Er Trimers on Cu(111)

Harald Brune, Stefano Rusponi, Marina Pivetta, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Fabio Donati, Aparajita Singha, Romana Baltic

We report magnetic hysteresis in Er clusters on. Cu(111) starting from the size-of three atoms. combining Xray magnetic circular dichroism, scanning tunneling microscopy, and mean-field nucleation theory, we determine the size dependent magnetic properties ...

LTCC and thick-film ceramic magnetic sensors for tokamak nuclear fusion

Duccio Testa, Peter Ryser, Christian Schlatter, Matthieu Toussaint, Lucas Güniat, Thomas Maeder, Caroline Jacq, Adrien Aymeric Thibault Corne, Martin Stöck, Philipp Windischhofer, Xinyue Jiang

The present contribution gives an overview of our work on non-conventional magnetic coil sensors for diagnostics and plasma stability control of nuclear fusion experiments in tokamaks. Instead of wire wound around a core, these devices consist of printed c ...

A Novel Flexible PCB Conductive Structure for Electrodynamic Bearings and Measurement in its Induced Voltage

Hannes Bleuler, Guoping Ding

This paper proposes the concept of FlexPCB(flexible Printed Circuit Board) conductive structure for electrodynamic bearings. It has three main advantages: easy "printing" of considerably thin conductive wires, resulting in potential reduction in stray eddy ...

Closed-loop magnetic bearing and angular velocity control of a reaction sphere actuator

Yves Perriard, Leopoldo Rossini

This article presents the first closed-loop magnetic bearing and angular velocity experimental results of a reaction sphere actuator for satellite attitude control. The proposed reaction sphere is a permanent magnet spherical actuator whose rotor is suppor ...
