Abstract

We developed detection system based on LaBr₃(Ce) scintillators. The system consisted of 1.5øx3" LaBr₃(Ce) detector, 3.5øx4" LaBr₃(Ce) detector and 110% Ge detector. The system was tested with top energy of 2.2 MeV quasi-monochromatic gamma-ray beam from the Laser Compton Backscattering (LCBS) at AIST. We could clearly detect the NRF excitation level from ¹¹B at 2.12 Mev.
