LaBr₃:Ce Detector Array (LABRA) for Active Nondestructive Assay of Special Nuclear Materials

抄録

LaBr₃:Ce detector array (LABRA) has been constructed to measure the nuclear resonance fluorescence (NRF) excitations from special nuclear materials (SNM). NRF is an active interrogation technique for assaying SNM that provides a unique signature to identify isotopic composition of an object nondestructively. At the meeting, we will present the performance of the LABRA to measure NRF excitation from ²³⁵U using quasi-mono-energetic g-ray beam at the HIgS facility.
