| Zusammenfassung | The neutron time-of-flight facility nELBE at the radiation source ELBE (Electron Linear accelerator with high Brilliance and low Emittance) of the Forschungszentrum Dresden-Rossendorf produces neutrons by bremsstrahlung photons through (γ, n)-reactions when electron pulses are impinging on a liquid lead target. The liquid lead is circulated by an electromagnetic pump and cooled by a heat exchanger far from the neutron source, thus reducing the amount of material close to the neutron source leading to less scattering of neutrons. The nELBE has been in operation for 1.5 years. The neutrons from the lead are going through a 2.4 m thick concrete wall to the measuring room via a collimator. The measurements of energy resolved neutron cross sections by a time-offlight arrangement are performed with a flight path of only 6 meters. This is possible since the electron beam has a pulse width less than 10 ps and the volume of the irradiated lead is only 1 cm³ resulting in a sharp temporal distribution without moderation of the neutrons. MCNP simulation of the beam profile compare well to the experimental beam profile scans, however more scattered neutrons and gamma rays in the beam halo are observed then simulated. The amount of neutrons which are scattered inside of the collimator was studied using an extra scattering shielding wall. Proceedings available online: dx.doi.org/10.2787/23116 |
