旗舰天文台需要具有超快读出、亚电子噪声性能和可扩展大幅面架构的单光子探测器。斯坦福大学的X射线天文学与观测宇宙学小组与麻省理工学院卡夫利研究所和麻省理工学院林肯实验室合作，正在为下一代探测器开发读出技术。采用单电子敏感读出（SiSeRO）放大器的原型通过重复无损读出（RNDR）展现出出色的读出噪声和光谱性能，在57个周期内实现了0.5 e$^-$噪声。我们对更长RNDR周期的噪声进行了建模，探索了热泄漏和碰撞电离等概率机制。在此展示模型结果，包括类似暗电流信号的统计极限。SiSeRO技术的成熟将提高软X射线能量下探测器的性能，填补未来X射线和紫外/可见光/近红外天文台的技术空白。
英文摘要
Flagship observatories require single-photon detectors with ultra-fast readout, sub-electron noise performance, and scalable large-format architectures. The X-ray Astronomy and Observational Cosmology group at Stanford, in collaboration with the MIT Kavli Institute and MIT Lincoln Laboratory, is developing readout technologies for next-generation detectors. Prototypes employing Single-electron Sensitive Readout (SiSeRO) amplifiers demonstrate excellent read noise and spectral performance using repetitive non-destructive readout (RNDR), achieving 0.5 e$^-$ noise in under 57 cycles. We have modeled noise for longer RNDR cycles, exploring probabilistic mechanisms such as thermal leakage and impact ionization. Here we present our model results, including statistical limits on dark current-like signals. Maturation of SiSeRO technology will improve detector performance at soft X-ray energies, addressing technology gaps for future X-ray and UV/visible/near-IR observatories.
