Temporal Response of Ultrafast Inorganic Scintillators for Future HEP Applications
Abstract
Future high energy physics experiments require ultrafast inorganic scintillators. Our previous investigation measured temporal response for various inorganic scintillators to pico-second X-rays at APS of ANL. In this paper we report temporal response of ultrafast inorganic scintillators to 511 keV γ-rays and 5.49 MeV alpha-rays from a 22Na source and an 241Am source respectively by using an MCP-PMT based test bench. 0.5 and 1.1 ns decay time is observed from BaF₂ and Lu₂O₃:Yb respectively. The BaF₂ result is also compared to 1.2 ns decay time observed at APS. Temporal response of other ultrafast inorganic scintillators, such as ZnO:Ga, Ga₂O₃, YAP:Yb, YAG:Yb and Cs₂ZnCl₄ etc., are also reported.
