AbstractTime-encoded imaging could be useful for searching potential radioactive sources for preventing illicit trans-portation and trafficking of nuclear materials. A 2-D, dual-particle, time-encoded imager was developed for gamma-ray and neutron source imaging. The influence of central detector and coded mask rotation speed to imaging performance, such as angular resolution, signal-to-noise ratio and detection time, was investigated by Am-Be neutron source imaging experiments. The EJ276 plastic scintillator (Size: phi 5.08 cm x 5.08 cm) and CLYC scintillator (Size: phi 2.54 cm x 2.54 cm) couple to photomultiplier tubes was set as the central detector, respectively. Under the experiment conditions (Am-Be neutron source; 300 mCi; 1.8 m), for the neutron and gamma-ray images with EJ276 detector, the best horizontal and vertical angular resolution was (3.7 degrees, 4.8 degrees) and (5.9 degrees, 6.6 degrees), minimum detection time was 100 s and 600 s, respectively; for the neutron and gamma-ray images with CLYC detector, the best horizontal, vertical angular resolution was (3.1 degrees, 3.1 degrees) and (3.5 degrees, 3.3 degrees), minimum detection time was 2200 s and 1600 s, respectively. For different central detector, the results showed that the smaller volume of detector, the better angular resolution; the lower detection efficiency, the longer detection time. For different rotation speed, too fast rotation speed can lead to failure to locate the source.
