Abstract
In the present work, selected dense rare-earth (RE) based scintillators such as gadolinium tantalate (GdTaO4), gadolinium tantalo-niobates Gd(Ta0.8Nb0.2)O4, lutetium based LuF3:Ce, LuAP:Ce, Lu2O3:Yb and Yb2O3 have been investigated for their gamma-ray sensing efficacy. The gamma-ray sensing properties of these RE scintillators have been confronted with modern lead tungstate (PWO) and lead fluoride (PbF2) scintillators being employed recently in high energy physics (HEP) experiments. The attenuation parameters namely linear attenuation coefficient (μ), half value layer (HVL) are compared for these rare-earth scintillators over wide energy range 1keV - 100GeV using Photon Shielding and Dosimetry (PSD) software toolkit. We also attempted to estimate build-up factors (BF’s) of these scintillation materials computed using the online platform Py-MLBUF. Our calculations depicted that scintillators containing high-Z rare earth elements exhibited better gamma-ray detection capabilities when compared with standard lead based PWO and PbF2 scintillators.
