THE EUROPEAN SPALLATION SOURCE

I will present an update on the European Spallation Source. The ESS is Europe’s next-generation neutron scattering facility, and is under construction in Lund, with the data management and software centre hosted in Copenhagen. It will be the world’s most powerful accelerator driven neutron source offering capabilities an order of magnitude beyond what currently exists. It is being built by a partnership of 13 European nations and has a total cost of roughly 2 billion Euros. Civil construction is nearing completion and operation of the first accelerator components is now starting. The initial suite of user instruments has been defined and we are making significant progress towards bringing the first three online in 2023. I’ll describe progress on the project, outline the technical challenges and some of the science opportunities that ESS will offer. I’ll also give an update on the work being done to understand and prepare for the start of operation of the facility in the coming decade.
