The Hybrid Spectrometer at SNS

Hybrid Spectrometer

Schematic of the HYSPEC instrument

Developed by a team from leading U.S. universities and national laboratories and an international group of neutron scattering experts, HYPSEC is a new concept in high-flux inelastic neutron spectrometry. It combines the time-of-flight technique used at pulsed sources, such as SNS, with the advantages of crystal spectrometers that use continuous neutrons.

HYSPEC is optimized for studying single-crystal samples in a broad variety of sample environments and allows for ground-breaking investigations of the low-energy, atomic-scale dynamical properties of crystalline solids. This instrument is equipped with a polarization analysis capability, making it the first world's first polarized beam inelastic instrument available at a pulsed spallation source.


HYSPEC's first users
