Description
SKADI [1] is a small-angle neutron scattering instrument being constructed at the European Spallation Source (ESS). This TOF instrument with 20 m collimation and 20 m sample detector distance will cover 3 orders of magnitude in Q-space simulateneously (10$^{-3}$ to 1 Å$^{-1}$), offer polarised scattering, as well as a versatile sample area of 3$\times$3 m $^2$. With a flux of approximately 8$\times 10^8$ n s$^{-1}$ cm$^{-2}$, due to a very efficient reflector-type neutron extraction, experiments with high flux requirements will be feasible, but also high resolution experiments with a more confined collimation. Thanks to a new scintillation-type detector [2], a semi-transparent beamstop allows measurements of very low Q-values. The large sample area, accessible from the top and by a side door, allows for very flexible, custom built sample environments for complex experimental setups, especially suited to in-situ experiments.
