The R&D work on new scintillator materials produced several high performing scintillators with an energy resolution better than that of NaI (6-7% at 662 keV). The best known is LaBr3:Ce because of its excellent and unmatched properties in term of energy (3 % at 662 keV), time (< 500 ps) resolution and efficiency (density of 5.1 g/cm3) for gamma ray detection. However, very new materials as CLYC, CLLB, CLLBC, Co-Doped LaBr3:Ce are appearing together with the new but better known scintillators as SrI2:Eu and CeBr3:Ce. These detectors could compete with LaBr3:Ce and, in general, outclasses NaI in terms of performances. The Cs2LiYCl6:Ce (CLYC) scintillator, that belong to the Elpasolite family, is an interesting scintillator for its capability to measure and discriminate gamma rays and neutrons simultaneously with excellent resolution. A CLYC scintillator can measure thermal neutrons , (if 6Li is used) but it can be used as a clean fast neutron spectrometer (if 7Li is used), due to 35Cl ions. We have tested the properties of i) two 1" x 1" CLYC scintillators (one enriched with 6Li and one enriched with 7Li) using either standard  and neutron sources and monochromatic neutrons beams ii) a 2"x2" CLYC scintillators (enriched with 7Li) and iii) we will test a 3"x3" (enriched with 7Li) CLYC crystal. Here we will present some results of the measurements
