The three-axis group operates seven three-axis spectrometers, instruments in which the monochromator, sample and analyser can each be aligned independently.
Inelastic scattering experiments on these instruments determine the dynamics of microscopic matter waves in arrays of atoms in single crystals and the analogous waves of magnetic spins in exotic materials.
