Abstract
- Because of its fast scintillation component with subnanosecond decay time, BaF2 crystals are considered as a candidate for ultrafast crystal calorimeters for future high energy physics experiments at the energy and intensity frontiers. Undoped BaF2, however, has a slow scintillation component with 600 ns decay time, which causes pile-up. In the part I of this paper, we report investigations on La doping in BaF2 crystals to suppress the slow component. While typical fast/slow (F/S) ratio observed in undoped BaF2 is 1/5, La-doped BaF2 crystals were found to improve this ratio to about 1/1. The overall F/S ratio, however, is considered not sufficient for pile-up suppression. [ABSTRACT FROM AUTHOR]
