CCAT-prime: Design and status of the Prime-Cam and Mod-Cam receivers and the first light 280 GHz MKID array for the Fred Young Submillimeter Telescope

The CCAT-prime Project's wide-field, six-meter aperture Fred Young Submillimeter Telescope (FYST) is currently under construction at 5600 m on Cerro Chajnantor in the Chilean Atacama Desert. CCAT-prime will address a suite of science goals, from Big Bang cosmology to star formation and galaxy evolution over cosmic time. Prime-Cam, a first-generation science instrument for FYST, will deliver over ten times greater sub-mm mapping speed than current and near-term facilities for unprecedented mm and sub-mm broadband and spectroscopic measurements with kinetic inductance detectors (KIDs). Mod-Cam, a first light and commissioning instrument for FYST, is now being integrated with the first 280 GHz instrument module and KID arrays for first light in 2024. Mod-Cam will be used to commission instrument modules for Prime-Cam, which can house up to seven instrument modules, each targeting unique science goals. We present the design and status of the Fred Young Submillimeter Telescope and the Prime-Cam and Mod-Cam instruments.
