Slicing a white neutron bunch via time-of-flight measurement for fast neutron resonance radiography and nucleus identification

Le résumé fourni par la source

The under-construction white neutron beam line at the China Spallation Neutron Source will be used mainly for nuclear data measurements. It will be characterized by its high flux and broad energy spectra. To exploit the beam line as a neutron imaging source, we propose a liquid scintillator fiber array for fast neutron resonance radiography (FNRR). The fiber detector unit has an extremely small exposed area, which will limit the event counts and separate the events in time, thus satisfying the requirements for single-event time-of-flight (SEToF) measurement. The current study addresses the physical design criteria for ToF measurement, including flux estimation and detector response. Future development and potential application of the technology are also discussed.
