Modélisation de matériaux supraconducteurs : application à un limiteur de courant

This thesis is focused on the modelling of superconducting materials, and in particular, high-temperature superconducting materials. This work is divided in two parts: first, the dynamic magnetic field mapping obtained by measurements is used in order to r ...

3D Finite Element Simulations of strip lines of a YBCO/Au Fault Current Limiter

Bertrand Dutoit, Bertrand Dutoit, Joseph Duron, Francesco Grilli

Geometrical aspects of the design of fault current limiters (FCL) have a great impact on their performance. Recently, the University of Geneva have presented optimized geometries obtained by splitting the FCL into many small dissipative lengths in order to ...

Finite-element modelling of superconductors in over-critical regime with temperature dependent resistivity

Bertrand Dutoit, Bertrand Dutoit, Joseph Duron, Francesco Grilli

In this paper, we present a new numerical model, in which both the thermal and the electromagnetic aspects of the over-critical current regime of HTS materials are taken into account. The electromagnetic and thermal equations have been implemented in finit ...

Dynamic field mapping for obtaining the current distribution in high-temperature superconducting tapes

Bertrand Dutoit, Bertrand Dutoit, Joseph Duron, Francesco Grilli

The magnetic field profile on the surface of Bi-2223/Ag tapes has been dynamically measured across the width of the samples. The experimental technique uses a Hall-probe array with 7 sensors connected to a multiple channel lock-in amplifier especially prog ...

Thermally Assisted Transition in Thin Film Based FCL: A Way to Speed Up the Normal Transition Across the Wafer

Bertrand Dutoit, Bertrand Dutoit, Joseph Duron

The adjunction of constrictions along the meander of a superconducting Fault Current Limiter (FCL) greatly improves its behavior thanks to a better distribution of the dissipative zones at the occurrence of a short circuit. This design works perfectly for ...

Computer Modeling of YBCO Fault Current Limiter Strips Lines in Over-Critical Regime With Temperature Dependent Parameters

Bertrand Dutoit, Bertrand Dutoit, Joseph Duron, Francesco Grilli

We present the results of an advanced numerical model for fault current limiter (FCL) based on HTS thin films in which both thermal and electromagnetic aspects are taken into account. This model allows simulating the behavior of FCL in the over-critical cu ...

Design status of ITER ECH upper launcher mirrors

René Chavan, Francisco Sanchez, Jean-Daniel Landis, Joseph Duron

The ITER ECH upper launcher is devoted to directing up to 8 2NM beams per port plug over half of the plasma cross section. A focusing mirror is used to achieve a very narrow deposition profile to stabilize MHD activity such as the neoclassical tearing mode ...
