High-Speed Detection of X-ray Pulses Using a Digital Counter Coupled with Perovskite Composite Scintillators
/PMMA composite, with an amplification stage, enabled accurate pulse counting up to 5 MHz (200 ns spacing). With a dead time of ∼20 ns, the system resolved nanosecond-spaced pulses without pile-up, enabling reliable pulse-by-pulse readout from a few counts per second to multimegahertz bursts. These results demonstrate that inhomogeneous composite scintillator films, when integrated with FPGA-based digital processing, provide a compact and scalable pulse counter for high-frequency radiation detection, effectively addressing the limitations of conventional bulky crystal detectors.
