Randomized trial demonstrates improved energy resolution in X-ray photon counting using CsPbBr3, suggesting practical applications for material discrimination.

Key Points

The aim is to evaluate the performance of CsPbBr3 perovskite detectors for spectrally resolved X-ray photon counting.
Investigated single-crystal CsPbBr3 detectors for photon counting.
Measured electric field resilience, incident photon count rates, and energy resolution under specific conditions.
Compared results to previous studies to assess improvements in detector quality and performance.
Achieved incident photon count rates of 230 kcps at 10% dead-time loss and 420 kcps at 30% dead-time loss.
Demonstrated energy resolutions of 5.2% at 59.5 keV and 2.9% at 122 keV for 241Am and 57Co isotopes, respectively.
Resolved K-edge features in X-ray spectra for indium, barium, and lead, indicating effective material discrimination.
