论文摘要
描述了硬X射线，高速，高动态范围科学X射线成像仪。该成像仪基于混合模式像素阵列检测器（MM-PAD）读数芯片，该芯片耦合到750微米厚的telluride（CDTE）传感器。完整的成像仪是一个2 x 3瓷砖阵列的MM-PAD传感器/读取芯片混合体。与硅传感器相比，CDTE改善了高能X射线的检测，从而使有效的X射线成像扩展到> 100 keV。检测器能够进行1 kHz成像，并且已经设计了像素内电路，以允许大于4 x 10^{6} 80 kev X射线的深度。集成前端的电荷可以定量测量高通量X射线图像，超出了光子计数检测器的功能。总结了检测器性能，并提出了实验测量。
A hard x-ray, high-speed, high dynamic range scientific x-ray imager is described. The imager is based on the mixed-mode pixel array detector (MM-PAD) readout chip coupled to a 750 micron thick cadmium telluride (CdTe) sensor. The full imager is a 2 x 3 tiled array of MM-PAD sensor/readout chip hybrids. CdTe improves detection for high energy x-rays as compared to silicon sensors, enabling efficient x-ray imaging to extend to >100 keV. The detector is capable of 1 kHz imaging and in-pixel circuitry has been designed to allow for well depths of greater than 4 x 10^{6} 80 keV x-rays. A charge integrating front-end allows for quantitative measurement of high flux x-ray images beyond the capabilities of photon counting detectors. Detector performance is summarized and experimental measurements are presented.
