Calibration of scintillator-based X-ray detectors for broadband laser-driven X-ray radiation
Abstract
Laser-driven X-ray sources produce broadband radiation with substantial shot-to-shot fluctuations, requiring calibrated detector-response models for quantitative measurements of photon fluence and spectral distribution. Scintillator-based flat-panel detectors, originally developed primarily for medical and industrial X-ray imaging, are increasingly being adopted for diagnostics of laser-plasma-based X-ray sources because they provide large-area, spatially resolved detection. We report the calibration of two complementary X-ray detector systems: a CsI:Tl-based flat-panel detector and a plastic-scintillator filter-stack spectrometer intended for spectral reconstruction. Both detectors were characterized using well-defined ISO 4037 N-series reference radiation qualities, providing controlled polychromatic X-ray fields for establishing their signal response and signal-to-fluence conversion.
