VESUVIO: a novel instrument for performing spectroscopic studies in condensed matter with eV neutrons at the ISIS facility

The VESUVIO project aims to provide unique prototype instrumentation at the ISIS-pulsed neutron source and to establish a routine experimental and the oretical program in neutron scattering spectroscopy at eV energies. This in strumentation will be specifically designed for high momentum, (20 Angstrom (-1) < q < 150 Angstrom(-1)), and energy transfer ((h) over bar w > I eV) i nelastic neutron scattering studies of microscopic dynamical processes in m aterials and will represent a unique facility for EU researchers. It will a llow to derive single-particle kinetic energies and single-particle momentu m distributions, n(p), providing additional and/or complementary informatio n to other neutron inelastic spectroscopic techniques.
