About the speaker
After getting a master degree from Ecole Superieure d Electricite (major: electrical engineering), Arnaud Devred got a PhD from Institut National Polytechnique de Lorraine in applied superconductivity (quench propagation study along superstabilized conductors). Then, he did several postdocs in the USA (SSC Laboratory) and in Japan (KEK) related to superconducting accelerator magnets, before joining CEA Saclay (France) to lead a Nb3Sn development program.
In the meantime, Dr. Devred has been collaborating for more than 10 years with CERN (Switzerland), where he contributed to the production monitoring of superconducting magnets for LHC. In 2002, he became leader of a European Joint Research Activity on high field accelerator magnets.
Since 2007 he is leader of the Superconductor Systems & Auxiliaries Section at the ITER International Organization, where he is responsible of the 1 billion dollar in-kind procurement of superconductors for the ITER magnet system. Since 2016 he is deputy leader of the ITER Magnet Division.
Abstract
The International Thermonuclear Experimental Reactor (ITER) project is a worldwide collaboration involving 7 parties (China, EU, India, Japan, Korea, RF and USA) to build a large superconducting tokamak aimed at demonstrating the feasibility of fusion for energy. It is based in Cadarache, in the South of France, where civil engineering work has already started.
After recalling the basic principles of a tokamak, we detail the superconducting magnet system that is at the heart of the machine and we present a status of the ongoing activities in the six parties manufacturing the 200 km (worth nearly US$ 1 billion) of Cable in Conduit Conductors needed for the coils.
