This figure presents the ToF spectra of neutrons leaking from natPb slabs after interaction with 3.2 MeV D-D neutrons. Similar to the D-T results, measurements were made at 60° and 120°.

The TOF is recorded for each neutron between the chopper and the detector and is used to calculate the wavelength: λ(Å)=3.956, where L=3.5 m is the chopper-to-detector distance. Hence, ( σ λ ...

The time-of-flight facility (n_TOF) facility for neutron measurements uses high-intensity neutron beams with a wide energy range to precisely measure neutron-related processes including ...

The measured ToF spectra shown here represent neutron leakage from natPb samples following exposure to 14.5 MeV D-T neutrons. Data were collected at both 60° and 120° scattering angles.
