International Standards and Conformity Assessment for all electrical, electronic and related technologies

Removing resistance!

Nomination of a new Chairman for IEC TC 90

One of two IEC TC (Technical Committee) Chairmen who began his term of office on 1 April 2012 is an expert in an area that has tremendous future development possibilities and scope. His committee is IEC TC 90: Superconductivity, set to revolutionize electronics by removing resistance.


The Frenchman Christian-Eric Bruzek began his first term of office as the Chairman of IEC TC 90: Superconductivity, on 1 April 2012. His candidature was supported by the Japanese NC (National Committee), holder of the secretariat of the TC.


Bruzek holds a PhD in metallurgy from the University of Lille where his thesis was entitled Optimization of the manufacturing process of NbTi [niobium-titanium].


For over 15 years Bruzek has been involved in the industrial development and manufacture of LTS (low temperature superconductor) and HTS (high temperature superconductor) devices and cables for a number of world leading industries and organizations including Alstom, LNE (Laboratoire national de métrologie et d'essais), the French national metrology laboratory and Nexans where, today, he holds the position of Superconductivity Expert and Project Manager.

Big future for superconductivity applications

IEC TC 90 was established in August 1989 and is a particularly active committee with 9 International Standards developed over a period of 7 years and 10 projects that are currently active. Indeed, the TC is in the only body presently working on the standardization of superconductivity and the electromagnetic properties of superconductors that, with their wires, cables and magnets, form the basis for applications, for example in the fields of health care, particularly as far as MRI (magnetic resonance imaging) is concerned, of transportation, material processing and electric power. In the near future, superconducting microwave components are also expected to be used widely in the field of communication and the market for such applications is predicted to grow substantially over the next 10 years.


At present, TC 90 is working on defining the terms and measuring methods for superconducting wires and films that can be used in a great number of applications. Due to the nature of some of the highly specific requirements for the latest high performance superconductors, some of the aspects of their standardization cannot be developed in advance by the TC but will fall into its work patterns as the technology progresses.

State of the art nuclear energy projects

Bruzek has worked on low temperature superconducting equipment and on the design and production of the strands and cables made of type II superconductors NbTi and Nb3Sn (niobium-tin) that are particularly important for high field accelerator magnets.


He has been involved in high energy physical collider projects: the SSC (superconducting super collider) – a precursor to the LHC (Large Hadron Collider). He has participated in projects concerning the LHC dipoles and quadripoles, the ATLAS (A Toroidal LHC Apparatus) and CMS (Compact Muon Solenoid) detectors – two of the seven particle detector experiments constructed for the LHC at CERN (European Organization for Nuclear Research) in Geneva, Switzerland – and on fusion reactors such as ITER (International Thermonuclear Experimental Reactor), the international project on nuclear fusion that is taking place in Cadarache in the south of France, together with the W7X (Wendelstein 7-X) stellarator, an experimental project being built at the Greifswald branch of the Max Planck Institute for Plasma Physics, to test an optimized magnetic field using stellarator nuclear fusion.


Bruzek is a member of several professional scientific congresses and organizations, a regular contributor of articles, owner of several patents and an international presenter on superconductivity.
