论文摘要
Cerro-Chajnantor Atacama望远镜Prime（CCAT-Prime）设施的Fred Young simbilimeter望远镜（FYST）将作为Prime-CAM作为一款有力的第一代摄像头托管Prime-Cam，其成像偏光仪具有多个波长和光谱仪器的成像偏振仪和光谱仪器，旨在在Ecoch epoch of Recoch ecoch of Recoch of Recoch ecoch of Recoch of Recoch ecoch ecoch ecoch ecoch eimapping中。在这里，我们介绍850 GHz（350微米）仪器模块。这将是Prime-CAM中最高的频率模块，也是天文和宇宙学调查最新颖的模块，它充分利用了Cerro Chajnantor上高5600米CCAT-PRIME位置的大气透明度。借助直径1.1度的场，850 GHz模块将用硅血小板Feedhorn偶联（均为NIST制造）部署约40,000个动力电感探测器（儿童），并提供前所未有的宽带强度和极化测量能力。 850 GHz模块将是解决有关我们自己的银河系中有关银河系，大爆炸宇宙学和星形组的迫切问题的关键。我们介绍了模块的动机和整体设计以及初始的实验室表征。
The Fred Young Submillimeter Telescope (FYST) at the Cerro-Chajnantor Atacama Telescope prime (CCAT- prime) Facility will host Prime-Cam as a powerful, first generation camera with imaging polarimeters working at several wavelengths and spectroscopic instruments aimed at intensity mapping during the Epoch of Reionization. Here we introduce the 850 GHz (350 micron) instrument module. This will be the highest frequency module in Prime-Cam and the most novel for astronomical and cosmological surveys, taking full advantage of the atmospheric transparency at the high 5600 meter CCAT-prime siting on Cerro Chajnantor. With a 1.1 deg diameter field, the 850 GHz module will deploy ~40,000 Kinetic Inductance Detectors (KIDs) with Silicon platelet feedhorn coupling (both fabricated at NIST), and will provide unprecedented broadband intensity and polarization measurement capabilities. The 850 GHz module will be key to addressing pressing astrophysical questions regarding galaxy formation, Big Bang cosmology, and star formation within our own Galaxy. We present the motivation and overall design for the module, and initial laboratory characterization.
