The Paul Scherrer Institut (PSI) is the largest Swiss Federal research Laboratory. The staff totals about 1200 and the turnover 150 M. PSI has build and operate a 750 kW accelerator driven CW neutron source SINQ. From late 1997 this facility has served as an International neutron scattering user facility (55% Swiss users, 40% EU users and 5% others) with 14 state of the art neutron instruments. SINQ is to date the highest power spallation facility world wide, and has 10 years of experience with solid water cooled Pb targets. For the 2006 operation cycle a liquid metal Pb/Bi target was designed, fabricated and licensed. The liquid Pb/Bi target was run at 750 kW as our production target during the second half of 2006, during which emissions and operational experience was gathered. The performance of the target was above expectation and the operation smooth and very reliable. After a cool down period the target will be examined for materials damage or corrosion to beam windows and other target components and for the radioactive inventory in the Pb/Bi. Finally the target will be disposed of. This will be the first liquid metal spallation target that has been through the whole process from design, through licensing and an extensive period of high power operation to final disposal. As ENSA as an institution has no employees and a very small financial turnover, both EC and the Board agreed in changing coordination from ENSA to PSI. The coordinator will be Peter Allenspach, present chairman of ENSA but employed by the PSI.

was founded in 1666. With eight faculties and a multitude of research centers and specialized institutes, it is today the largest unit for research and higher education in Sweden with 40,600 students and 5,500 staff. ESS Scandinavia Secretariat was set up as an independent unit within Lund University by the Swedish Government in July 2007. A consortium of 21 interested bodies from Scandinavia - academic, industrial and administrative - whose goal is to obtain the decision in favour of building ESS in Lund together with VR and Vinnova support the aim of building up neutron scattering competence and industrial relevance in Sweden, Denmark and Norway. The Swedish government announced its candidature to host ESS in February 2007.

is one of the largest universities in the UK and is ranked in the top ten universities in the UK for research excellence and for its market share of UK university research funding. It currently has over 7300 staff, 26000 students, an annual turnover of over £380M and an annual research income of £80M. Leeds University, together with York and Sheffield Universities, is a member of the research alliance known as the White Rose University Consortium which has collaborated closely with the regional development agency, Yorkshire Forward, in the Yorkshire- ESS (YESS) venture. YESS has worked to promote ESS nationally and within Europe as a necessary European neutron facility and also as a flagship facility at the core of Yorkshire's science and innovation strategy. Although YESS does not have legal status, it has been responsible for coordinating and executing Yorkshire and Humberside's regional scientific, technical, political and socioeconomic evaluation of the ESS and dealing with all issues pertaining to siting the ESS in Yorkshire.

is one of the 15 Helmholtz Research Centres in the Federal Republic of Germany, with 4.300 members of staff being one of the largest research institutions in Europe. In Jülich, scientist of the disciplines of physic, chemistry, biology and medicine and the engineering sciences base their cooperation on key competences in physics and scientific computing.
The FZ- Jülich has played a key role in the former ESS project which let to the ESS project proposal now being part of the ESFRI list. At present being not a site contender, Jülich is prepared to contribute to the preparations for the ESS project bringing in particular its competences in the field of project organization (costing), health, safety and environment issues as well as in technical areas relating to the target.

is a consortium of 38 Universities in Italy with a status of legal entity. The purpose of CNISM is the promotion of condensed matter research within the network of the associated Universities, also supporting the collaboration with the major national research bodies. The number of associated researchers ranges around 1500 people with a full coverage of the research areas relevant to condensed matter, atomic physics and optics. A large number of neutron users from different fields are associated to CNISM and technical capabilities in several areas of neutron scattering, including neutron sources and neutron instrumentation are available from CNISM groups. A contribution to the construction of the former ESS technical case was given by groups now active under CNISM.

is recognized as one of the oldest and largest worldwide centres in the field of fundamental and applied magnetohydrodynamics (MHD) research.The employees of the Institute of Physics (about 90 employees) carry out complex investigations of the electrodynamic, hydrodynamic and heat/mass transfer phenomena occurring in liquid conducting media subject to the influence of electromagnetic fields of different types, in particular, with respect to the problems of engineering physics and liquid metal technologies. Numerous versions of electromagnetic pumps and other specific devices for alloys transport, stirring, pouring, and conditioning have been developed for ferrous and non-ferrous metallurgy, for the technologies of composite material production and growth of semiconductor single crystals and so on. The wide experience of the Institute of Physics in the field of work with liquid metal media, the appropriate experimental equipment and developed specific methods and procedures of measurements in molten metals and alloys allow to perform physical and numerical simulations of different technological processes in order to work out new original MHD methods for controlling the hydrodynamic and heat/mass transfer characteristics of melts in metallurgy and single crystal growth from the melt.
