High density, high Z low Gamma background CeBr3 Scintillator Detector

CeBr3 is characterized by its relatively high density, high Z, and its proportional response to gamma rays. The typical energy resolution provided by the material is 4% FWHM for 662 keV. Thanks to its fast light pulse rise time, CeBr3 detectors can provide sub-nanosecond time resolutions only slightly inferior to BaF2 detectors. In addition, the material exhibits fast decay times of 20 ns with negligible afterglow. With a background count as low as <0.001 c/cc/s in the Ac-227 complex, CeBr3 presents a distinct advantage over other high-resolution scintillators which suffer from this intrinsic activity. There are currently two versions of CeBr3 that are commercially available, standard background and low background (LB) CeBr3. The low background variety results in less activity in the Ac-227 peaks when compared to standard CeBr3. Standard: 0.025 c/s/cc and Low Background Background: 0.00125 c/s/cc in the Ac-227 complex.

Properties

Notes:
1.Detector signal exceeds this value, a truncation will occur.
