UppCANs: Bringing neutrons to the users — •Maximilian Wolff — Department for Physics and Astronomy, Uppsala University

Neutrons provide unique and essential tools for research across many disciplines ranging from basic sciences to engineering and studies of heritage artefacts. The present neutron facilities are currently decreasing in number. This overall shortage will not be compensated by ESS offering the best available brilliance but a limited total number of beam days.

Ultra-compact accelerator driven neutron sources (UCANS) can provide small facilities and enable easy accessibility by bringing neutron instruments close to the users. These use modest energy protons (~18 MeV) that impact on a light target. This allows an extremely compact design of the moderators. The small size and optimised source design provide good brilliance at reasonable cost. Dedicated instrumentation can compete in performance with current small to medium size facilities.

I will present a project for UppCANs in Uppsala. When built, this would provide neutrons for 5 to 7 beam ports and offer a broad range of modern capabilities in materials research allowing the community at modest cost to both complete straightforward measurements and prepare to exploit world leading instruments elsewhere.
