Title Perspectives for electronvolt neutron spectroscopy at long pulse spallation neutron sources
Contributors
Abstract Pulsed neutron sources open up new fields of investigation in condensed matter, as the intense fluxes of epithermal neutrons (above 500 meV) allow for achieving unique energy and wave vector transfers. The investigation of matter at small time and space scales provides an insight into atomic momentum distribution n(p) and mean kinetic energy through the deep inelastic neutron scattering (DINS) technique. On the other hand, epithermal neutrons allow access to the kinematical region characterised by > 1 eV and q < 10 Å-1, i.e. the high energy inelastic neutron scattering (HINS) regime. HINS enables experimental studies on the dispersion relations of high-energy excitations in metals, semiconductors and insulators, high-lying molecular rotational– vibrational states, molecular electronic excitations, and the electronic level in solids. The neutron spectrum at Long (LPSS) and Short (SPSS)- Spallation Sources also contains a large amount of high-energy neutrons (above 1 MeV). This special feature may be well exploited for electronic chip irradiation for the study of the so-called Single Event Effects (SEE). The measurement of SEEs is very important for the electronic industries to assess the robustness of their products, especially those featuring nanometric sizes that represent the new generation electronic components.
