本文介绍了用于快速时间分辨X射线衍射研究的92 × 100像素阵列探测器样机的X射线测试结果。这种集成检测器能够以微秒帧时间拍摄多达八张全帧图像。它由一个硅层组成，吸收X射线，凸点键合到一层CMOS电子器件上，其中每个像素都有自己的处理，存储和读出电子器件。测试表明，信号性能特征与基于磷光体的CCD X射线探测器相当，具有大大提高的时间分辨率、相当的线性度和增强的点扩展。这个原型是一个测试模块，正在前往一个适合专门操作的更大的探测器。讨论了需要改进的领域。
X-ray test results from a prototype 92 × 100 pixel array detector (PAD) for use in rapid time-resolved X-ray diffraction studies are described. This integrating detector is capable of taking up to eight full-frame images at microsecond frame times. It consists of a silicon layer, which absorbs the X-rays, bump-bonded to a layer of CMOS electronics in which each pixel has its own processing, storage and readout electronics. Tests indicate signal performance characteristics are comparable with phosphor-based CCD X-ray detectors, with greatly improved time resolution, comparable linearity and enhanced point spread. This prototype is a test module en route to a larger detector suitable for dedicated operation. Areas of needed improvement are discussed.
