高强度的X射线源与高效、高速的X射线成像仪相结合，为高速时间分辨实验开辟了新的可能性。硅像素阵列探测器(PAD)是一种非常灵活的技术，目前正在作为一种快速成像器开发。我们描述了康奈尔垫的结构，它能够以亚微秒的帧时间工作。这种100×92 像素原型焊盘由一个像素化的硅二极管层和一个相应的像素化的互补金属氧化物半导体电子层组成，前者用于将X射线直接转换为电荷载流子，后者用于处理和存储产生的电荷。每个像素二极管都被焊料凸点连接到它自己的像素电子设备上，该像素电子设备由一个电荷积分放大器、一个八个存储电容器阵列和一个输出放大器组成。该体系结构允许快速连续存储8个完整帧，最小积分时间为每帧150 ns，帧间死区时间为600 ns。我们描述一下..。
Intense x-ray sources coupled with efficient, high-speed x-ray imagers are opening new possibilities of high-speed time resolved experiments. The silicon pixel array detector (PAD) is an extremely flexible technology which is currently being developed as a fast imager. We describe the architecture of the Cornell PAD, which is capable of operating with submicrosecond frame times. This 100×92 pixel prototype PAD consists of a pixelated silicon diode layer, for direct conversion of the x rays to charge carriers, and a corresponding pixellated complementary metal–oxide–semiconductor electronics layer, for processing and storage of the generated charge. Each pixel diode is solder bump bonded to its own pixel electronics consisting of a charge integration amplifier, an array of eight storage capacitors and an output amplifier. This architecture allows eight complete frames to be stored in rapid succession, with a minimum integration time of 150 ns per frame and an interframe deadtime of 600 ns. We describe the ...
