PSI is entirely responsible to build the polarised neutron reflectometer ESTIA at the European Spallation Source ESS in Lund, Sweden. The lead ESTIA scientist Artur Glavic (LNS/NUM) has now simulated a virtual tour of the neutrons travelling through the instrument from the focusing neutron guide to the detector.
ESTIA has been designed in particular for reflectometry on tiny samples. This animation takes you through the whole beamline from the moderator to the detector, following the neutron pulse through the functional components of the instrument such as choppers, apertures, polarisers and sample environment equipment.
