Spectroscopy

ORNL’s 11 spectroscopy instruments provide users the unprecedented ability to study excitations in materials over 8 orders of magnitude in energy transfer (from 10s of neV to ~1 eV). This naturally leads to a diverse scientific program covering areas such as quantum materials, energy- related materials, soft matter, complex fluids, and biology. The instrument suite is composed of four triple-axis spectrometers, four direct geometry spectrometers, two indirect geometry spectrometers, and one spin-echo spectrometer.
