Summary
The presented work aims at a radiochemical analysis of the radionuclide inventory of a solid lead target irradiated with high energetic protons in the spallation neutron facility SINQ at Paul Scherrer Institute. Lead samples from the vicinity of the beam entry have been extracted. A detailed γ-analysis shows the radial distribution of selected radionuclides relative to the incoming beam. The concentrations of these nuclides are evaluated in dependence on the proton beam profile.
Keywords : Spallation neutron source; Radionuclide inventory; Lead target; γ-Spectroscopy; Radiochemistry
