Neutrons with energies between 0.1 and 1 eV slightly above the typical thermal spectrum of a research reactor, often-called hot neutrons, are valuable probes for different scientific applications. Their use in the neutron diffraction, spectroscopy, absorption or irradiation experiments often provides results of superior quality in comparison to thermal neutrons or even results unreachable by the use of the latter. At FRM II, hot neutrons are generated by a dedicated secondary source in the moderator tank, which shifts the spectrum of the moderated neutrons towards higher energies. A beamline with two channels pointing to the centre of the hot source extracts the re-moderated neutrons towards the two dedicated experimental installations POLI and HEiDi. Here, we present the design of the hot neutron source and related instrumentation. In addition, a few representative examples of their use from the fields of crystallography, magnetism and nuclear physics are shown to demonstrate their usefulness. |
