The full strength of the VESUVIO+ beamline on the Target Station 1 (TS1) will be exploited to globally tackle the local phenomenon of the tuneable thermal expansion in two samples, (i) a negative thermal expansion (NTE) exhibiting (Sc,Fe)F3; and (ii) a positive thermal expansion (PTE) exhibiting Lix(Sc,Fe)F3; x ~0.4, by concurrently measuring neutron transmission, neutron powder diffraction, neutron Compton scattering, in a mass-selective mode (MANSE), enabling distinct separation of Li recoil peak and partial separation of Sc, Fe and F recoil peaks, and neutron Gamma Dopplerimetry as applied to the Scandium neutron-Gamma resonance. Using the combination of information obtained concurrently from these four techniques, spanning the entire incident neutron spectrum accessible on TS1, will shed a light on the thermal expansion tuneability of framework framework materials
