16. Periodic Report Summary - NEUTRONSOURCEESS (The European spallation neutron source (ESS))

Abstract: The ESS preparatory phase (NEUTRONSOURCEESS) had the overall goal to pave the way to and to facilitate a site decision and a final decision to construct and to operate the ESS. Work on technical and scientific aspects where on a very high standard already from the previous ESS project and only specific investigation (especially target material) was needed. Therefore the major effort was to cover more political, societal and environmental aspects in this ESS-PP project.

One of the goals - i.e. to reach a site decision - could be reached with (besides others) the help of this project. After the site decision in spring 2009, we re-adjusted the project to this new boundary condition by eliminating still open site-specific work which became redundant and by focusing on question of major significance for ESS in Lund. We did this by writing an amendment (dated 17 November 2009), which was approved by EU on 8 March 2010.

At the end of this reporting period which also is the end of the whole preparatory phase project a wealth of information has been collected, compiled and assessed (total of 33 deliverables with a total of several thousand pages) which will help the ESS project to realise the facility in Sweden.

ESS in Lund will be the brightest source of neutrons that will be used for experiments to look inside the materials. It will be the best neutron source worldwide for practically all classes of instruments. ESS will provide much more intensity than the present neutron sources, brighter neutrons beams that, with a suite of more than 40 neutron scattering instruments, will enable scientist of all disciplines to investigate materials in situ, in vivo, in real time and for real life applications. This will have enormous positive consequences for society, industry and technology. It will also retain and strengthen Europe's lead in neutron science in quality and quantity.
