摘要：

At the reactor FRM at Technical University of Munich energy-selective neutron radiography and tomography experiments were performed. For an energy separation of the neutrons from the primary beam a mechanical velocity selector was used. The radiography images show a different contrast of the investigated elements for neutron energies below and above their Bragg-cutoff energy. A comparison between the standard and energy-selective neutron tomography is presented. In spite of a reduction of the neutron intensity due to the velocity selector technique a realistic experimental time in order of some hours for the tomography experiment was achieved.
