本文介绍了为智利在建FYST研制的Prime-Cam仪器的设计、测试与部署进展,该仪器将大幅提升亚毫米波段测绘能力,计划2026年末集成后开展早期科学观测以探索宇宙相关问题。
AI 中文摘要
Prime-Cam是CCAT天文台6米口径弗雷德·杨亚毫米波望远镜(FYST)的第一代科学仪器,该望远镜正在智利阿塔卡马沙漠查南托山海拔5600米处建造。Prime-Cam在亚毫米波段的测绘速度将比现有设备高10倍以上,可在1.4-0.3毫米(220-850吉赫兹)波段实现前所未有的宽带和光谱测量。当完全配置时,Prime-Cam将在7个独立优化的仪器模块中部署超过10万个动力学电感探测器。CCAT合作组将借助Prime-Cam解决一系列科学目标,从大爆炸宇宙学到宇宙时间内的星系演化和恒星形成。Prime-Cam计划于2026年末集成到FYST中,随后利用280和350吉赫兹仪器模块开展为期一年的早期科学观测。我们讨论了直径1.8米的Prime-Cam接收机和280吉赫兹仪器模块的设计与实验室测试情况,并提供了部署状态和早期科学计划的最新进展。
英文摘要
Prime-Cam is a first-generation science instrument for the CCAT Observatory's six-meter aperture Fred Young Submillimeter Telescope (FYST), under construction at an elevation of 5600 m on Cerro Chajnantor in Chile's Atacama Desert. Prime-Cam will deliver over ten times greater mapping speed at submillimeter wavelengths than current facilities for unprecedented broadband and spectroscopic measurements in windows between 1.4 -- 0.3 mm (220 -- 850 GHz). When fully populated, Prime-Cam will field over 100,000 kinetic inductance detectors across seven independently optimized instrument modules. With Prime-Cam, the CCAT Collaboration will address a suite of science goals, from Big Bang cosmology, to galaxy evolution and star formation over cosmic time. Prime-Cam is scheduled for integration in FYST in late 2026, followed by a year of early science observations with the 280 and 350 GHz instrument modules. We discuss the design and in-lab testing of the 1.8-m diameter Prime-Cam receiver and 280 GHz instrument module, and give an update on deployment status and early science plans.
