Neutron scattering is a powerful technique to reveal structure and dynamics in condensed matter, espacially in hydrogen containing materials. For these systems, the experimental investigations are often done by using different instruments to achieve a full set of information on a given, such as structure and dynamics accessing different regions of the kinematic space (Q, w). The possibility of exploit a large interval of neutron energy in neutron scattering to access simultaneously wide ranges of Q and w is not well exploited at present. Indeed, in principle, a time of flight diffractometer-spectrometer, the spectrometer operating in the inverse geometry configuration can be set-up to access complementary (Q,w) regions, allowing for simulatenous structural and dynamical studies on the same gauge volume of sample and thermodynamic and enviromental backgorund conditions.
