Abstract and subjects
Ultrafast inorganic scintillators with excellent radiation hardness are required for future HEP experiments at the energy and intensity frontiers as well as GHz hard X-ray imaging for the proposed MaRIE project. In this paper, we present an investigation on temporal response of fast and ultrafast inorganic scintillators. Temporal response of BaF2:Y, BaF2, YAP:Yb, YAG:Yb, ZnO:Ga, Ga2O3, YAP:Ce, LYSO:Ce, LuYAP:Ce, LuAG:Ce, YSO:Ce and GAGG:Ce was measured by ultrafast MCP-PMTs using cosmic rays and 510 keV γ-rays from a Na-22 source at Caltech, and by 30 keV X-ray bunches of 27 and 50 ps length at the Advanced Photon Source facility of Argonne National Laboratory. Their application for future HEP experiments and GHz hard X-ray imaging is discussed.
