Abstract

For the validation of differential cross section data neutron spectrum measurements in deep penetration single material benchmarks are of great value. At the Euracos facility consisting of a highly enriched 235-U disk of 80 cm diameter thermal neutrons from a 250 Kw Triga reactor are converted into fission neutrons which are in turn used to irradiate large blocks of iron (145x145x130 cm**3) or sodium (145x145x400 cm**3). In these assemblies the neutron spectra were measured as a function of the penetration depth in the energy range 15 KeV to 10 MeV using a combination of proton recoil spectrometers (proportional gas counters of different pressures and a liquid scintillator).
