AI中文摘要：
未来的战略X射线任务，如由大天文台成熟计划（GOMaP）所针对的任务，需要快速、低噪声的X射线成像光谱仪。为实现此类计划所需的速度和噪声性能，斯坦福团队与麻省理工学院卡夫利研究所（MKI）和麻省理工学院林肯实验室（MIT - LL）合作，正在开发增强型X射线电荷耦合器件（CCD）和利用定制专用集成电路（ASIC）的读出系统。本文报告了使用一些最新的MIT - LL CCD与斯坦福开发的多通道读出芯片（MCRC）ASIC所实现的能量分辨率和噪声性能。此外，提出了一种新的采样方法，用于同时优化输出栅极（OG）、复位栅极（RG）和复位漏极（RD）偏置，结合新的集成快速求和阱（SW）和RG时钟操作模式，可实现未来X射线望远镜所需的数据速率和噪声。最后，介绍了噪声功率谱密度（PSD）和波形分析方法，并提出了一个用于表征和理解输出级噪声行为的物理模型。
英文摘要：
Future strategic X-ray missions, such as those targeted by the Great Observatories Maturation Program (GOMaP), require fast, low-noise X-ray imaging spectrometers. To achieve the speed and noise capabilities required by such programs, our Stanford team, in collaboration with the MIT Kavli Institute (MKI) and MIT Lincoln Laboratory (MIT-LL), is developing enhanced X-ray charge-coupled devices (CCDs) and readout systems that leverage tailored application-specific integrated circuits (ASICs). Here, we report the energy resolution and noise performance achieved using some of the latest MIT-LL CCDs in conjunction with Stanford-developed Multi-Channel Readout Chip (MCRC) ASICs. Additionally, we present a new sampling method for simultaneous optimization of the output gate (OG), reset gate (RG), and reset drain (RD) biases which, in combination with new integrated fast summing well (SW) and RG clock operation modes, enables the data rates and noise required for future X-ray telescopes. Finally, we present noise power spectral density (PSD) and waveform analysis methods and posit a physical model for characterizing and understanding output stage noise behavior.
