Development of an ultra-fast BaF₂-based detector
Abstract
BaF₂ is one of the fastest known scintillators, emitting at 220 nm with sub-nanosecond decay constant; Excellent for timing applications. 4.88 g/cm³ → High detection efficiency; At 15 cm thick, nearly 100% efficient for gammas up to 10 MeV. Problem: ~80% of the total light output consists of slower (600 ns decay constant) emission peaked at 310 nm; High count rate → pile up. Goal: develop a BaF₂-based detector that leverages the fast emission component for optimal timing characteristics; Suppression of slow component.
