Analysis of the Karlsruhe Neutron Transmission experiment using MCNP with various beryllium nuclear data

Analysis of the KANT experiment on beryllium using TRIPOLI-4 Monte Carlo code

“…Neutron leakage spectra were recorded from the spherical beryllium shells between the source energy and 10 eV [6,9,10].…”

“…Fig. 1 shows the KANT experiment configurations and the beryllium shell dimensions used in this study [9].…”

“…Various detectors were employed to cover, in separate runs, the wide energy range: an NE-213 liquid scintillator detector for energies above 3.2 MeV, several different proton recoil proportional counter tubes for the range from 3.2 MeV down to 100 keV, and the time-of-flight (TOF) technique for energies below 100 keV [9].…”

“…Ref. [9]. The 2-D view of the deuteron ion beam tube and tritium target configuration is helpful to understand the internal structures but detail dimensions of these structures are not described.…”

“…Clearly calculation models for internal structures of beryllium shells in Refs. [6] and [9] are different.…”
