论文摘要
MOD-CAM是CCAT PRIME项目的六米孔弗雷德·弗雷德（FYST）的首个灯光和调试工具，目前正在智利阿塔卡马沙漠（Atacama Desert）的Cerro Chajnantor上建造5600 m的望远镜（FYST）。 Prime-CAM是一种用于FYST的第一代科学工具，其映射速度将比当前和近期设施的映射速度高10倍，用于前所未有的280-850 GHz宽带和微波动力学感应探测器（MKIDS）的光谱测量。 CCAT-Prime将解决一系列科学目标，从大爆炸宇宙学到宇宙时间的星系和银河发展。计划在2024年以早期科学观测来使用包含280 GHz仪器模块的FYST上的Mod-Cam部署。MOD-CAM将用于测试Prime-CAM的仪器模块，该模块可容纳多达七个仪器模块。我们讨论了直径为0.9 m，长长的mod-cam接收器和直径40厘米280 GHz仪器模块的设计和状态，在40 K，4 K，1 K和100 MK处冷阶段。我们还描述了仪器模块的低温读数设计，以实现在18个网络中超过10,000个MKID的读数。
Mod-Cam is a first light and commissioning instrument for the CCAT-prime project's six-meter aperture Fred Young Submillimeter Telescope (FYST), currently under construction at 5600 m on Cerro Chajnantor in Chile's Atacama Desert. Prime-Cam, a first-generation science instrument for FYST, will deliver over ten times greater mapping speed than current and near-term facilities for unprecedented 280-850 GHz broadband and spectroscopic measurements with microwave kinetic inductance detectors (MKIDs). CCAT-prime will address a suite of science goals, from Big Bang cosmology to star formation and galaxy evolution over cosmic time. Mod-Cam deployment on FYST with a 280 GHz instrument module containing MKID arrays is planned for early science observations in 2024. Mod-Cam will be used to test instrument modules for Prime-Cam, which can house up to seven instrument modules. We discuss the design and status of the 0.9 m diameter, 1.8 m long Mod-Cam receiver and 40 cm diameter 280 GHz instrument module, with cold stages at 40 K, 4 K, 1 K, and 100 mK. We also describe the instrument module's cryogenic readout designs to enable the readout of more than 10,000 MKIDs across 18 networks.
