AI 中文摘要
宾夕法尼亚州立大学高能天体物理探测器与仪器实验室与Teledyne成像传感器公司合作，研发出了下一代事件驱动型X射线混合CMOS探测器。该探测器是一款混合电荷器件（HCD），拥有1024×1024阵列、21微米间距的像素，每个像素内集成了比较器以实现事件驱动型读出。该探测器的全帧操作读出速度最高可达150Hz，而事件驱动型操作仅读出超过用户设定电荷阈值的像素，有效读出速率最高可达10kHz。本文报告了宾夕法尼亚州立大学过往的探测器研发工作，并描述了这些新型探测器及其预期的性能提升。
英文摘要
The Penn State University High Energy Astrophysics Detector and Instrumentation Lab, in collaboration with Teledyne Imaging Sensors, has developed a next-generation event-driven X-ray hybrid CMOS detector. This detector is an HCD with a 1,024x1,024 array of 21-micron pitch pixels, featuring a comparator in each pixel to enable event-driven readout. While the full frame operation of this detector can reach readout speeds of up to 150 Hz, this event-driven operation allows readout of only those pixels that surpass a user-set charge threshold, enabling effective rates of up to 10 kHz. Here we report on the past detector development efforts at Penn State and describe these new detectors and expected performance improvements.
