Our first excellence domain is the characterization of high-Tc superconductors, AC losses measurement. quench experiments with normal zone propagation velocities measurements are made on coated conductors
Our second domain of excellence is the numerical modelling of high temperature superconductors, the goal is to find and propose to manufacturers the optimal conductor and device configurations.
This group belongs to the School of Computer & Communications Sciences at EPFL. Formerly it was part of the Laboratory of Nonlinear Systems (LANOS) under the supervision of Professor Martin Hasler. Our main research fields are the measurements, modelling and characterization of high-Tc superconductors. This kind of materials can carry very large electrical currents with very low energy dissipation (compared to traditional copper or aluminum conductors) and they can be, therefore, used in new generation power systems for devices such as fault current limiters, electric cables, transformers, motors and generators. Among the main impediments to an immediate large scale industrial utilization of the high-Tc superconductor technologies are the AC losses occuring in the presence of alternating transport currents and/or magnetic fields.

The IEEE Council on Superconductivity sponsors the Van Duzer Prize, awarded to the best contributed paper published in IEEE Transactions on Applied Superconductivity during each volume year
The award is restricted to regular submissions to the IEEE Transactions on Applied Superconductivity to encourage authors to prepare well written and comprehensive contributions which may have exceptional archival values and are likely to be cited frequently by other authors. Papers submitted for publication through scientific conference special issues are not eligible.
Candidates for the Prize may be nominated by the Editors of the Transactions and judged by the Editor in Chief. Papers are scored on the following criteria:
