Abstract (en)
[origin: WO9622550A2] The assay of a drum is performed by treating the drum as a collection of virtual subvolumes, each separately treated in the system response. Then, neutron measurements are made so as to include azimuthal orientation and time relative to a generator pulse in the data stream. An external matrix probe provides a detailed measure of neutron transmission through a drum, so that scans of mock-up drums can be compared to the scan of a target drum, so that appropriate system response functions can be determined.
