AI 中文摘要
激光驱动的X射线源产生具有大量逐次波动的宽带辐射，这需要校准的探测器响应模型来进行光子注量和光谱分布的定量测量。基于闪烁体的平板探测器最初主要用于医学和工业X射线成像，因其能提供大面积、空间分辨检测，越来越多地用于基于激光等离子体的X射线源诊断。本文报告了两个互补的X射线探测器系统的校准：一个基于CsI:Tl的平板探测器和一个用于光谱重建的塑料闪烁体滤光片堆栈光谱仪。两个探测器都使用明确的ISO 4037 N系列参考辐射特性进行了表征，提供可控的多色X射线场以建立其信号响应和信号与注量的转换。
英文摘要
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.
