Monitoring of neutron fields and innelastic neutron scattering

Abstract

In the diploma thesis two experiments are described and analysed, namely fast neutron emission in the interaction of heavy charged particles (129Xe and 86Kr) at approximately 50 MeV/A with a natural copper target performed at GANIL, and measurement of secondary gamma radiation released in inelastic neutron scattering on an iron sphere using a 252Cf neutron source performed at RC Rez. In the first experiment, an organic liquid scintillation detector EJ309 for measuring neutrons with energies of up to tens of MeV, and in the second experiment a coaxial germanium GC4019 gamma spectrometer were used. GC4019 detector internals were characterized based on X-ray images and detection efficiencies measured for different standards and geometries to prepare a full MCNP detector model and to completely evaluate the measured data in the future.
