Testing of the PARIS LaBr3-NaI phowich detector with high energy gamma-rays

Abstract : We report on tests of LaBr3:Ce-NaI:Tl phoswich detectors with $\gamma$-rays at various $\gamma$-ray energies, up to 22.56 MeV, using radioactive sources and nuclear reactions induced by proton beams delivered by accelerators at IFJ PAN Kraków and PLF Mumbai. Two-dimensional analysis of complex waveforms recorded with digital electronics is compared to analog discrimination methods. Both approaches allow to resolve the LaBr3:Ce and NaI:Tl signal components, and to construct clean associated $\gamma$-ray spectra. A digital algorithm to be implemented for the PARIS scintillator array is investigated.
