ABSTRACT
We have measured time resolutions of a cylindrical CeBr3 scintillator of 1-inch in height and 1-inch in diameter coupled to two different fast photomultiplier tubes, Hamamatsu R9779 and Photonis XP20D0, as a function of applied high voltages and different settings of a Constant Fraction Discriminator ORTEC 935. The time resolution was measured using a time-delayed coincidence set-up involving a fast reference detector. The best result of 119(2) ps at 60Co energies was obtained for the CeBr3 crystal coupled to the Hamamatsu PMT. This result is comparable to the resolution of 107 ps reported for a LaBr3(Ce) crystal of the same size. For the coupling of the CeBr3 scintillator to the Photonis PMT we got the time resolution of 146(2) ps.
