Title: New scintillator materials for future and present facilities

In the recent years LaBr3:Ce crystals started a new generation of high performing scintillator detectors. In fact, a large number of different, new and promising scintillators are now becoming commercially available, as for example CeBr{sub 3}, CLYC, SrI{sub 2}. Some others, like GYGAG:Ce, CLLB, CLLC, will be available in the near future. The CLYC crystal enriched with {sup 6}Li provides extremely high efficiency for thermal neutron identification and detection with performances comparable to {sup 3}He tubes. The CLYC enriched with {sup 7}Li can provide the direct measurement of the neutron kinetic energy from the energy pulse signal. The most recent R and D activity shows that ‘co-doping’ technique has the effect to improve the crystal proportionality and the mechanical properties thus significantly increasing the reliability and energy resolution of LaBr{sub 3};Ce and CeBr{sub 3} scintillators. Such a new generation of detectors can be the backbone for the detectors array of the future accelerator facilities as for example ELI-NP which will provide very intense high-energy γ-ray beam with very low bandwidth.
