Back to Who is who in neutrons
On 7th October at the ENSA General Assembly Hannu Mutka was nominated Chairman of ENSA. He starts now a task that requires a large amount of time and effort. Mutka's progress in neutron scattering during his working life demonstrates that he is prepared to meet any challenge. He and his team will surely fulfil the expectative.

	Dr. Hannu Mutka Could you send me some personal data? Where are you coming from... Where did you study ... HM - I was born and had my school education in Joensuu (Finland). After finishing my thesis (not in neutron scattering) I returned to Finland and worked in the field of neutron scattering, participating in a collaboration - construction of a diffractometer - with Gatchina (present St. Peterburg Nuclear Physics Institute). Then after a short stay in Toulouse (France), involved with electron microscopy, I came to Grenoble.
	Alpine skiing My youth's passion and a durable source of joy is alpine skiing, I'm actively involved in the life of 'Club de Ski Alpin de Villard de Lans'. Racing is now too fast for me but last year I took the exam of 'juge régional' with the Fédération Française de Ski. Organising races for young and also experienced skiers is an refreshing outdoor activity and a good way of making friends.
	Post-graduate Studies and Degrees At Helsinki University of Technology and University of Helsinki, Finland, 1976-77 At Université de Paris-Sud, Orsay, France, 1978-82 Docteur de Troisième Cycle (Solid State Physics), Université de Paris-Sud, Orsay 1980 Docteur-ès-Sciences Physiques, Université de Paris-Sud, Orsay 1982
ILL	ILL scientist since 1986 Hannu Mutka is is a member of of the Time-of-Flight & High Resolution Spectrometers Group (TOF/HR) at ILL. He is responsible (together with John Stride) for the Instrument IN4 - Thermal neutron TOF spectrometer. The IN4 is a time-of-flight spectrometer used for the study of excitations in condensed matter.
SFN	Vice-Président - Société Francaise de la Neutronique Since May 1997 Hannu Mutka (ILL) is part of the Administration Board of the French Neutron Society. The society represents the French neutron users, the professionals working in the French neutron sources, and the potential industrial partners interested in neutron methods. On June 2004, at the General Assembly in Praz sur Arly, it was established that the society will continue to benefit from his leadership in his position as vice chairman.
ENSA Web page	Chairman of ENSA and ENSA French delegate The European Neutron Scattering Association, ENSA, is an affiliation of national neutron scattering societies and committees which directly represents neutron beam users. Hannu Mutka is the French delegate in representation of the French users through the "Société Française de la Neutronique". Now he has been nominated as the Chairman of the Association, substituting Prof. Fabrizio Barocchi.
Influence of defects and impurities on Charge Density Wave Systems	Publications Hannu Mutka's work and work done in collaboration have been published in the most prestigious magazines: Physica, Inorganic Chemistry, Applied Physics, Polyhedron, Physical Review and Physical Review Letters, Canadian Journal of Physics, Europhysics Letters, Nature etc. His review chapter in the book 'Advances in the Crystallographic and Microstructural analysis of Charge Density Wave Modulated Crystals' (eds. Boswell and Bennet, Kluwer) deals with the earlier work he did before involvement with neutron scattering. His long-standing collaborations with the swiss ETHZ-PSI-Bern groups have produced several high impact papers, as for example : "Large isotope effect on the pseudogap in the high-temperature superconductor HoBa2Cu4O8 Rubio Temprano D, Mesot J, Janssen S, Conder K, Furrer A, Mutka H, Muller KA. Phys. Rev. Lett. 84, 1990–1993 (2000)
	ECNS-Guest editor He was member of the organisation committee of the European Conference for Neutron Scattering in Montpellier, with the special task as guest-editor for the proceedings of ECNS'03 ( in collaboration with R. Vacher, F. Leclercq and E. Courtens), published by Physica B, 2004.
'Highly Frustrated Magnetism 2003'	Conference Chairman He was the chairman of the international conference 'Highly Frustrated Magnetism 2003' in Grenoble, a highly successful meeting organised with support from the Neutron Round Table (FP5) (Proceedings published in J. Phys.Condens. Matter vol 16 number 11, 2004)
ESS	Designing and promoting ESS He is one of many scientists from all over Europe that had joined together to elaborate the technical design and to work on the realization of the European Spallation Source Project. (ESS) He was part of the ESS Instrumentation Task Group team (Direct Geometry Spectrometers). He was involved in the SFN effort to promote ESS, the TRESSES meeting at Saint-Rémy-lès-Chevreuse in 2001.
nmi3	Participating in Integration activities Participation in the Neutron Round Table meetings (FP5) and NMI3 (FP6) meeting as an invited ENSA representative.
