FISH: A thermal neutron imaging station at HOR Delft

Abstract We report on the development of a thermal neutron imaging station FISH at the nuclear research reactor HOR, Delft University of Technology. FISH will serve as a unique new imaging facility within The Netherlands and also within at least 400 km radius, for national and international users from science and industry. This paper gives an overview on the characteristics and performance of the beamline and instrument, as determined in a collaboration with the Paul Scherrer Institut in Switzerland.
