论文摘要
在亚毫米和远红外（FIR）波长的天文数据中包含大量重要科学信息，包括有关尘土星系，星系簇和恒星形成区域的信息；但是，由于这些研究涉及的技术困难，这些波长是天文学最少的领域之一。在过去的20年中，已大量的努力致力于开发亚毫米和毫米波长的天文仪器和望远镜。 检测器的数量是此类工具的重要特性，并且是当前研究的主题。未来的望远镜将需要多达数十万探测器来满足视野，扫描速度和解决方案的必要要求。大型像素计数是使用动力学检测器（KID）技术的多重检测器开发的好处之一。 本文介绍了基于儿童仪器的读数电子设备的各个方面的开发，该仪器能够在亚毫米/毫米波长成像阵列中获得的最大检测器计数之一：总计2304个检测器。本文介绍的工作是在2013年至2015年之间的Caltech Imbilimeter Persvoration（CSO）的多波长亚毫升电感摄像头（Music）实施的。
A substantial amount of important scientific information is contained within astronomical data at the submillimeter and far-infrared (FIR) wavelengths, including information regarding dusty galaxies, galaxy clusters, and star-forming regions; however, these wavelengths are among the least-explored fields in astronomy because of the technological difficulties involved in such research. Over the past 20 years, considerable efforts have been devoted to developing submillimeter- and millimeter-wavelength astronomical instruments and telescopes. The number of detectors is an important property of such instruments and is the subject of the current study. Future telescopes will require as many as hundreds of thousands of detectors to meet the necessary requirements in terms of the field of view, scan speed, and resolution. A large pixel count is one benefit of the development of multiplexable detectors that use kinetic inductance detector (KID) technology. This paper presents the development of all aspects of the readout electronics for a KID-based instrument, which enabled one of the largest detector counts achieved to date in submillimeter-/millimeter-wavelength imaging arrays: a total of 2304 detectors. The work presented in this paper had been implemented in the MUltiwavelength Submillimeter Inductance Camera (MUSIC), a instrument for the Caltech Submillimeter Observatory (CSO) between 2013 and 2015.
