Abstract
A neutron source illuminates suspect material leading to emission of gamma rays characteristic of the isotopes present. The system measures Compton scattering of emitted gamma rays using detectors with three dimension event localization capability. Detection does not require full energy deposition. A spatial correlation of projection vectors is computed by a reconstruction that searches for solutions that generate spatial correlation. Identification and location for contraband material is determined from solutions that generate spatial correlation.
