Neutron Spectrometer

(device determining the energy of received free neutrons)

A Neutron Spectrometer measures the Kinetic Energy (KE) of received free neutrons. As such, it is a type of Particle Spectrometer. Some types are used in labs when probing molecular and subatomic structure with Neutron Scattering and some types are used in planetary probes to detect water at or below the body's surface, through the changes in KE due to neutron scattering by Hydrogen.

They are sometimes combined with Gamma-Ray spectrometers, I believe because they have related scientific goals: detection of various specific Elements at or below the surface.
