论文摘要
未来的远红外天文学任务将需要大量的探测器，具有异常低的噪声等效功率（NEP），其中一些任务概念要求成千上万的探测器，NEP的NEP低于几美元$ \ times 10^{-20} $ w/$ w/$ \ sqrt {\ sqrt {\ sqrt {\ mathrm {hz}} $。尽管在实现这一目标方面取得了很大进展，但今天的探测器系统并不存在。在这项工作中，我们提出了一种提供引人注目的前进路径的设备：纵向接近效应（LOPE）过渡边缘传感器（TES）。我们设计，制造和表征的倾斜度也表现出前所未有的敏感性，并具有测量的电气NEP为$ 8 \ times 10^{ - 22} $ w/$ w/$ \ sqrt {\ Mathrm {hz}} $。这代表了最先进的> 100倍的进步，将TES探测器推向了该政权，即使是最雄心勃勃的大型和最寒冷的未来太空工具的目标。
Future far-infrared astronomy missions will need large arrays of detectors with exceptionally low noise-equivalent power (NEP), with some mission concepts calling for thousands of detectors with NEPs below a few $\times 10^{-20}$ W/$\sqrt{\mathrm{Hz}}$. Though much progress has been made toward meeting this goal, such detector systems do not exist today. In this work, we present a device that offers a compelling path forward: the longitudinal proximity effect (LoPE) transition-edge sensor (TES). With a chemically-stable and mechanically-robust architecture, the LoPE TES we designed, fabricated, and characterized also exhibits unprecedented sensitivity, with a measured electrical NEP of $8 \times 10^{-22}$ W/$\sqrt{\mathrm{Hz}}$. This represents a >100x advancement of the state-of-the-art, pushing TES detectors into the regime where they may be employed the achieve to goals of even the most ambitious large and cold future space instruments.
