Coincidence/Multiplicity Photofission Measurements (original) (raw)

A series of experiments using the Idaho National Laboratory (INL) photonuclear inspection system and a Los Alamos National Laboratory (LANL) supplied, list-mode data acquisition method have shown enhanced performance utilizing pulsed photofission-induced, neutron coincidence counting between pulses of an up-to-10-MeV electron accelerator for nuclear material detection and identification. The enhanced inspection methodology has applicability to homeland security, treaty-related support, and weapon dismantlement applications. For the latter, this technology can directly support Department of Energy/NA241 programmatic mission objectives relative to future Rocky Ridgetype testing campaigns for active inspection systems.
