Abstract
A wellbore inspection apparatus and a corresponding method of operation are described. The wellbore inspection apparatus comprises a neutron generator that produces, by a fusion reaction, a neutron and a corresponding charged particle. An associated particle imaging (API) detector comprises a particle detector array that detects the corresponding charged particle. The particle detector array comprises a plurality of particle detector elements that facilitate determining a trajectory of the neutron based upon a detection, by a particular one of the plurality of particle detector elements, of the corresponding charged particle. A gamma-ray detector assembly comprises a set of gamma-ray detector elements, and a set of collimating structures, where adjacent pairs of the set of collimating structures define a gamma-ray path for a gamma-ray arising from an inelastic collision of the neutron.
