| الوصف: | International audience; In the framework of homeland security, the Nuclear Measurements Laboratory of CEA Cadarache is studying the detection of Special Nuclear Materials hidden in sea-going cargo containers. Proof of principle experiments done in the DANAIDES facility of CEA Cadarache shows the feasibility of detecting some dozen of grams of highly enriched uranium by means of neutron interrogation with a 14 MeV D-T pulsed neutron generator and an array of EJ-200 plastic scintillators. We show that uranium can be detected by measuring correlated induced-fission prompt neutrons and gamma rays in coincidence, which is a first attempt with such detectors without neutron-gamma PSD capabilities, or more classically by detecting fission-induced delayed gamma rays. |
