CCAT-prime: Prime-Cam on the Fred Young Submillimeter Telescope

Prime-Cam will be a first-generation science instrument for the CCAT Observatory's new six-meter aperture Fred Young Submillimeter Telescope (FYST). The FYST is currently under construction for first light in 2023 at an exceptional 5600 m elevation site on Cerro Chajnantor in Chile's Atacama Desert. Prime-Cam on the FYST will deliver over 10 times greater mapping speed than current and near-term facilities with unprecedented 210--860 GHz broadband and spectroscopic measurements using kinetic inductance detector arrays. Prime-Cam's 1.8 meter diameter cryostat will house up to seven independent instrument modules, including broadband polarization-sensitive modules and imaging spectrometer modules equipped with Fabry-Perot interferometers. CCAT-prime will complement upcoming cosmic microwave background surveys and address a suite of science goals including Big Bang cosmology, the formation of the first galaxies during the Epoch of Reionization, star formation within the Milky Way, Sunyaev–Zel'dovich observations of galaxy clusters, galaxy evolution over cosmic time, galactic magnetic fields, and transient astronomy. We present the science goals as well as telescope and instrument designs for Prime-Cam on the FYST.
