论文摘要
微波动力电感探测器（MKID）是高度可扩展的探测器，在来自高空气囊伸缩望远镜和太空样实验室环境的远红外，表现出几乎背景限制的灵敏度。此外，探测器具有丰富的设计空间，具有许多优化的参数，可以在广泛的动态范围内进行高度敏感的测量。由于这些原因，选择了MKID进行低温大量强度映射的实验（Apaim），这是一种气球传播的望远镜，在420-540 GHz的高海拔大气环境中靶向几乎背景限制的性能。我们描述了MKID在呼吸的特定背景下的优化，并提供适用于更广泛应用程序的一般结果。扩展了既定的音调频率跟踪方法，我们表明读数功率优化可以在动态范围内进一步改进。
Microwave Kinetic Inductance Detectors (MKIDs) are highly scalable detectors that have demonstrated nearly background-limited sensitivity in the far-infrared from high-altitude balloon-borne telescopes and space-like laboratory environments. In addition, the detectors have a rich design space with many optimizable parameters, allowing highly sensitive measurements over a wide dynamic range. For these reasons, MKIDs were chosen for the Experiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM), a balloon-borne telescope targeting nearly background-limited performance in a high-altitude atmospheric environment from 420-540 GHz. We describe MKID optimization in the specific context of EXCLAIM and provide general results that apply to broader applications. Extending the established approach of tone frequency tracking, we show that readout power optimization enables significant, further improvement in dynamic range.
