Characterization of the neutron beam at nELBE

The neutron time-of-flight setup nELBE at the Helmholtz-Zentrum Dresden-Rossendorf uses an intense electron beam impinging on a liquid-lead target to produce neutrons in the energy range from about 10 keV to 10 MeV. This neutron source will be used to measure fast-neutron induced reactions with relevance for future nuclear transmutation facilities and nuclear waste management. The spatial profile, the intensity, the energy distribution and the time structure of the nELBE neutron beam have been investigated and the techniques how they were measured are explained in this work.
