论文摘要
Prime-Cam是Cerro Chajnantor Atacama望远镜Prime(CCAT-PRIME)设施的第一代工具。用于Prime-Cam的850 $〜$ GHz模块将探测所有仪器模块中最高的频率。我们描述了F $λ$间距,梁大小,像素灵敏度和检测器计数之间的850 $〜$ GHz光学系统的参数空间。我们介绍了针对CCAT PRIME的850 $〜$ GHz仪器模块的光学设计的优化。我们进一步描述了低温RF链设计的开发,以容纳$> $ 30的读取线,以读取低温测试床内的41,400个动力学电感探测器(儿童)。
Prime-Cam is a first-generation instrument for the Cerro Chajnantor Atacama Telescope-prime (CCAT-prime) Facility. The 850$~$GHz module for Prime-Cam will probe the highest frequency of all the instrument modules. We describe the parameter space of the 850$~$GHz optical system between the F$λ$ spacing, beam size, pixel sensitivity, and detector count. We present the optimization of an optical design for the 850$~$GHz instrument module for CCAT-prime. We further describe the development of the cryogenic RF chain design to accommodate $>$30 readout lines to read 41,400 kinetic inductance detectors (KIDs) within the cryogenic testbed.
