“…[11,12] In addition to maximizing high energy gamma detection probability, the detector design must minimize interference from low energy gammas (i.e. it must be able to reject low energy gammas without undue loss of the high energy gamma signal).…”

“…Prior work has shown that interference from gammas emitted between neutron pulse phases by non-SNM materials is low at gamma energies of 2.5 MeV and above. [12] Therefore the plastic scintillator configuration and signal readout and processing methods chosen should maximize gamma detection probability above 3 MeV while minimizing gamma detection probability below 2.5 MeV. As discussed earlier, the light collection efficiency for events in the scintillator bars varies with location in the bar, energy resolution will be poor.…”

“…These systems can be utilized to inspect cargo in shipping containers at seaports, border crossings, and air transport containers, or be deployed as mobile inspection systems. For the pulse-die away technique for locating SNM, pulsing with no neutrons between pulses, as demonstrated here, is important for detection of the resultant delayed fission neutrons [5].…”
