The challenge of HighNESS is not one that can be met by any single scientific institution. For that reason, the project is a collaboration of world-leading experts in areas of science and technology ranging from condensed-matter research to fundamental physics, and from neutron behaviour to engineering.

Led by the European Spallation Source (ESS), the consortium represents the core of the neutron community in Europe, with seven other partners from seven European countries: the Institut Laue-Langevin in Grenoble, France, the Forschungszentrum Jülich in Germany, the Università degli Studi di Milano-Bicocca in Italy, the Danmarks Tekniske Universitet near Copenhagen, the Paul Scherrer Institut in Villigen, Switzerland, Mirrotron Ltd in Budapest, Hungary, and Stockkholms Universitet in Sweden.

Together, they will be able to provide the best outcome possible for the second ESS source, to maximise the potential for research with high-intensity cold neutrons.
