The Origins Space Telescope (Origins) will have a 5.9-m diameter primary mirror cooled to 4.5 K and will be equipped with three instruments, two of which will cover the far-IR (λ = 25 to 588 μm). These far-IR instruments will require large arrays (∼104 detectors) of ultrasensitive detectors, with noise equivalent powers (NEPs) as low as 3 × 10 − 20 W Hz − 1/2. Kinetic inductance detectors (KIDs) have already demonstrated the array format, modularity, and readout multiplexing density requirements for Origins; the only aspect that requires improvement is the per-pixel sensitivity. We show how KIDs can meet the sensitivity target, focusing on two existing architectures that together demonstrate the key necessary attributes. Arrays of antenna-coupled coplanar waveguide resonators have achieved NEPs of 3 × 10 − 19 W Hz − 1/2 in laboratory demonstrations at 350 μm; they demonstrate excellent material properties as well as array-level integration and performance. Lumped element detectors such as those under development for balloon-borne spectroscopy at 10 to 350 μm demonstrate flexibility in coupling to shorter-wavelengths, reducing active volume, and providing a means for suppressing capacitor noise. A straightforward combination of the elements of these already-demonstrated devices points to a low-volume design that is expected to meet the Origins sensitivity targets.

起源太空望远镜的动电感检测器

Origins太空望远镜（原产地）将具有一个直径为5.9 m的主镜，冷却至4.5 K，并将配备三台仪器，其中两台将覆盖远红外（λ= 25至588μm）。这些远红外仪器将需要大型阵列（约104个探测器）的超灵敏探测器，其噪声等效功率（NEP）低至3×10-20 W Hz-1/2。动力学电感检测器（KID）已经证明了Origin的阵列格式，模块性和读出多路复用密度要求。唯一需要改进的方面是每像素灵敏度。我们将重点介绍两个现有的体系结构，它们一起展示关键的必要属性，从而说明KID如何满足敏感度目标。在实验室演示中，以天线耦合的共面波导谐振器阵列在350μm处实现的NEP为3×10 − 19 W Hz − 1/2。它们展示了出色的材料特性以及阵列级的集成和性能。集总元件检测器（例如正在为10-350μm的气球型光谱仪开发的检测器）在与较短波长耦合，减小有效体积并提供抑制电容器噪声的手段方面表现出灵活性。这些已经演示过的设备的元素的直接组合指向了一种小批量设计，有望满足Origins灵敏度目标。集总元件检测器（例如正在为10-350μm的气球型光谱仪开发的检测器）在与较短波长耦合，减小有效体积并提供抑制电容器噪声的手段方面表现出灵活性。这些已经演示过的设备的元素的直接组合指向了一种小批量设计，有望满足Origins灵敏度目标。集总元件检测器（例如正在为10-350μm的气球型光谱仪开发的检测器）在与较短波长耦合，减小有效体积并提供抑制电容器噪声的手段方面表现出灵活性。这些已经演示过的设备的元素的直接组合指向了一种小批量设计，有望满足Origins灵敏度目标。
