LAGRANGE (Large Area GRaphite ANalyser for Genuine Excitations)

This neutron spectrometer is dedicated studies of high energy dynamics in condensed matter

IN1-Lagrange will be a universal instrument oriented to studies of lattice and molecular excitations in complex materials in the form of phonon density of states (PDOS). Unique at ILL by the combination of high energy range and unrestricted temperature interval for samples. Unique in the world by the combination of high resolution and high count rate flexible resolution variation in a broad range the highest sensitivity.

• The highest performance in the case of hydrogen-containing materials
  • e.g. Life science: H-bonding, its role in biological function of proteins
• Dynamics and bonding: functional abilities of materials; ground step in developments
• Structure of complex molecular compounds
• Location in the host matrix of molecular groups active in selectivity processes
• Materials and compounds
  • hydrides of metals and intermetallic compounds (future energy storage)
  • zeolites and metallic catalysts (molecular sensitivity mechanisms)
  • nano-crystalline materials for industry and applications (fullerenes, nanotubes, polymers, amorphous materials and composites, surfaces and porous media)
  • industrially used stainless steels (mechanisms of embrittlement in aggressive environment)
  • high-Tc superconducting ceramics (highly efficient electric and magnetic devices)
  • geochemistry matters for earth science (large-scale processes related to water and hydro-carbons)
• Magnetism (rare-earth based compounds, inter-multiplet transitions)
