Abstract

The feasibility of using highly pixelated light sensors as neutron detectors is the subject of a collaboration between ILL and ESS Bilbao. The fast paced development of camera sensors can meet the future challenges of neutron detection if an optical coupling able to increase the signal to noise ratio and enlarge the detection area is identified. Fiber optics tapers seem the best candidates, but issues about their radiation resistance and price make photographic objectives a more sensible choice. The performances of photographic optics have been tested as well as the light output of several thermal neutron scintillators. Thanks to the use of a highly transmissive optics, single neutrons could be observed in 6LiF/ZnS(Ag) for the first time.
