ORTEC LABR
LaBr₃(Ce) scintillation detectors with better resolution than NaI(Tl)
Lanthanum bromide, LaBr₃(Ce), scintillation detectors with high light output and a fast decay time. Compared with NaI(Tl) they give better energy resolution and stability and higher throughput at high count rates; the resolution varies little over a wide range of count rates. Four crystal sizes from 1 × 1 to 3 × 3 in, used with the ORTEC digiBASE, digiDART or NIM electronics.
- Detector type
- LaBr₃(Ce) scintillator with 14-pin photomultiplier1
- Energy resolution
- Per the ordering information: LABR-1x1 3.5% guaranteed; LABR-1.5x1.5 3.0% (target); LABR-2x2 and LABR-3x3 3.5% (target)1
