Abstract :
One of the essential requirements of the tagged neutron inspection system, which is the principle of the EURITRACK project, is an efficient and inexpensive gamma ray detector. For this purpose properties of cylindrical 3"times3" and 5"times5" BGO, and 3"times3", two different 5"times5", and a rectangular 5"times5"times10" NaI(Tl) scintillators were explored. In this communication we report on light yield, energy and time resolution of the investigated crystals at high energies of gamma-rays. Additionally, results of Monte Carlo simulations of the crystals´ efficiencies are compared to peak-to-total ratios obtained experimentally for various combinations of PMTs and the scintillators
