Correcting for Emission-Time Effects in Neutron Time-of-Flight Data Using Multiple Time Spectra

An analytical method has been developed whereby neutron time-of-flight spectra may be corrected for emission-time dispersion without requiring a priori knowledge of the source time distribution or employing time-dependent spectral measurements. The method relies on time-of-flight spectra only, obtained experimentally at several flight-path distances, rather than the customary measurement at a single detector position.
