Francesco Romanelli (2006-2014)

Francesco Romanelli was nominated as ‘EFDA Associate Leader for JET’ in 2006. Following the organisational union of EFDA and EFDA JET, he became additionally EFDA Leader in 2009, and held both positions until 2014, the year in which the EFDA Agreement was substituted by the EUROfusion Agreement.

Francesco Romanelli graduated in Physics and started his career as researcher at the ENEA Research Centre in Frascati. He started his scientific collaboration with JET in 1994. In 1996 he was appointed Deputy Director of the Fusion Department in Frascati. Since then he has been a member of several European Fusion Committees. From 2003 to 2006 he was Chairman of the EFDA-STAC. In this role Francesco Romanelli was involved in the negotiations for ITER and the Broader Approach. Since 2007 he has been the European standing expert in the ITER-STAC.

With Francesco Romanelli the row of ‘JET Directors’ and ‘EFDA Associate Leaders’ ends. In 2014 the European research programme has been profoundly re-structured when EUROfusion came into force and succeeded EFDA. Since then the position ‘JET Leader’ and ‘EFDA Associate Leader’ is not anymore part of the organisational chart of EUROfusion.

Jérôme Paméla (2000-2006)

Jérôme Paméla was born in France, in 1955. He graduated from the “Ecole Polytechnique” in Paris in 1977 and finished his PhD at the DESY laboratory in Hamburg in 1984. After his PhD he changed his field of research from High Energy Physics to Thermonuclear Fusion. In 1984 Paméla joined the French Atomic Energy Agency (CEA) Controlled Thermonuclear Fusion Department in Fontenay-aux-Roses near Paris, and then moved to Cadarache in southern France in 1986. In his role as physicist he was involved in the development of negative ion based neutral beam heating, and later as group leader and European Task Area Leader. For several years he was responsible for collaborations with Japan in that field. In 1995-96 he was involved in and ultimately led a first phase of studies preparing Cadarache to bid for siting ITER. In 1996 the physicist was appointed Head of the Controlled Thermonuclear Fusion Department of the CEA and Head of the Euratom-CEA Association. In 1999 he was seconded to Culham, UK, as EFDA Associate Leader for JET followed by a second secondment to Garching as EFDA leader. Jérôme Paméla took on the role of Director at Agence ITER France (CEA) in January 2010. He currently serves as the chair of the EUROfusion General Assembly, the highest decision-making body in EUROfusion.

Jean Jacquinot, June to September 1999

Jean Jacquinot, a physicist, has devoted his entire career to magnetic fusion. He has worked in JET for 18 years and became its director 1n 1999. A member of the ITER advisory committee as early as 1992, he led the CEA activities in fusion from the year 2000 to 2004 while taking part in the ITER international negotiations. Jean Jacquinot is presently a scientific advisor to the French High Commissioner for atomic energy.

Martin Keilhacker (1992-1999)

Martin Keilhacker, born in Königsberg/Ostpreussen in 1934, studied physics at the Technical University of Munich and finished with a doctor’s degree in 1959. He started his career in 1960 as a member of the scientific staff at Max-Planck-Institut für Plasmaphysik (IPP) at Garching near Munich, Germany. During this period he worked on theta pinches (1960-1965) and collisionless shockwaves (1965-1973) and led, as Project Head, the tokamak experiment ASDEX (1973-1985). In this period fall the successful test of the divertor concept and, in 1982, the discovery of the H-mode with improved energy confinement.
In 1986 Keilhacker was appointed as Associate Director and two years later as Deputy Director of JET Joint Undertaking with responsibility for the Experimental Department and Theory Division. In 1992 he took over the post of Acting Director and in 1993 Keilhacker was appointed as Director of the JET Project. Under his direction JET produced in 1997 a record fusion power of 16 MW. He retired in 1999. In February 2016, Keilhacker passed away, leaving behind his legacy of important contributions to the fusion community.

Paul Henri Rebut (1985-1992)

Paul-Henri Rebut, born in 1936, started his career in 1958 as research scientist at the CEA, French Commissariat à l’Energie Atomique. From this time already, his researches were on plasma physics and thermonuclear controlled fusion.

After having built the French Tokomak of Fontenay-aux-Roses, TFR, he conceived and directed the European Tokamak, JET from 1985 to 1992 as director. Under his direction in November 1991 JET produced for the first time a significant amount of fusion power from a magnetically confined thermonuclear plasma.

In 1992 he was appointed Director of ITER and in charge of its conception. Back to France in 1998 he was advisor to the Haut Commissaire for Atomic Energy (until 2004) and to l’International Science and Technology Center (2000 to 2004). Currently he serves as a regular consultant for the ITER Organisation.

Hans-Otto Wüster (1978-1985)

Hans-Otto Wüster was born in Wuppertal, Germany, in 1927. He studied physics at the University of Cologne, where he finished his PhD. From 1949 to 1956 he worked in the Institute of Theoretical Physics, Cologne. Afterwards he moved into the field of high-energy nuclear physics and for the following 15 years was concerned with Deutsches Elektronen-Synchrotron in Hamburg (DESY). It was there where he was successively head of the theory group, head of data processing and chief scientist, director of operations, and a member of the management committee.
In 1971, he joined the European Organization for Nuclear Research (CERN), Geneva, Switzerland, as the deputy to the director general (Sir John Adams) during construction of the 400-GeV Super Proton Synchrotron. On completion of the task in 1975, CERN was reorganized and Dr Wüster became a member of the directorate and the management committee with responsibility for programs, budgeting and planning. In June 1978, Wüster was appointed director of the JET Joint Undertaking. He died suddenly in 1985. As a token of the gratitude JET owes its first director, his widow Dr Gisela Wüster is still invited to all official ceremonies.
