Abstract

A multi-detector modular coincidence gamma-ay spectrometer is currently being designed and constructed for use at the UK's National Physical Laboratory (NPL) with the aims of being usd for direct measurement and metrological standardisation of nuclear decay activities. In the first generation the NPL-based NAtional Nuclear Array (NANA) will consist of 12 individual halide scintillation detectors placed in a high-efficiency geometry around a well-defined central point source position. This short conference paper provides some details of the measured detector module responsesfor potenial LaBr3(Ce) and CeBr3 detectors which may be used in the NANA array. Peliminary GEANT4 simulations of the array's full energy peak efficiency and expected gamma-ray coincidence response are presented.
