Abstract
Isotopically enriched boron carbide 10B4C thin layers were deposited on Si substrates using pulsed DC sputtering technique. The surface density of 10B atoms vs. layer thickness was determined from SEM/EDS and proton backscattering spectrometry experiments. Good agreement was found between measured and calculated neutron absorption efficiencies when considering beam hardening of the poly-energetic cold neutron beam. The optimal layer thickness for maximum neutron absorption and ionoluminescence yield induced by the 10B(n α,)7Li reaction products in a scintillator was ascertained.
