A compact system capable of determining the spectrum of incident neutrons from 25 meV to 5 MeV at high total detection efficiency based on the use of multi-element solid state neutron detectors embedded in hydrogenous neutron moderator.

Other uses include:

• Well logging for hydrocarbons or other resources.
• Fissile Materials Identification– fingerprint from passive detection of spontaneous fission neutrons.
• Source Identification– fingerprint specific active detection of prompt neutrons.
• Shielding/Transport– empirically determined spectra for MCNP feedback.

• The ability to collect a full neutron spectra from a single configuration.
• The ability to resolve a neutron spectra without unfolding(i.e., faster and more accurate).
• Detectors that thin and are weakly perturbing (i.e., relative to volume hungry 3He or scintillator-based detectors).
