Measurements and calculations of the neutron emission spectra from materials used in fusion-fission reactors

Description

Spherical assemblies of copper with radii (R) equal to 1.0, 3.0, and 5.0 mean-free-paths (mfp) for 14-MeV neutrons, niobium (R.0.9 and 3.2 mfp), /sup 232/Th (R.1.0 mfp), and /sup 238/U (R.1.0 and 3.1 mfp) have been bombarded with a centered nominal 14-MeV neutron source. The neutron leakage spectra have been measured from 0.8 to 14 MeV using a stilbene scintillator, time-of-flight techniques, pulse-shape discrimination and about 10-m flight paths. The measured spectra are compared with calculations carried out with TARTNP, a coupled neutron-photon Monte Carlo transport code
