CCAT-prime is a new 6 m crossed Dragone telescope designed to measure the Sunyaev-Zel’dovich effects of galaxy clusters, the CMB polarization and foregrounds, and the [CII] emission from the Epoch of Reionization. CCAT-prime will observe from a 5600 m altitude site on Cerro Chajnantor in the Atacama Desert. The novel optical design of the telescope combined with a high surface accuracy, and the exceptional atmospheric conditions of the site will enable sensitive broadband, polarimetric, and spectroscopic surveys at sub-mm to mm wavelengths. Prime-Cam, the first light instrument for CCAT-prime, consists of a large cryostat that can house seven individual instrument modules that use multichroic transition edge sensors, kinetic inductance detectors, and Fabry-Perot interferometers. Prime-Cam is currently being developed, and the telescope is under construction to achieve first light in 2021. CCAT-prime is also a potential telescope platform for the CMB Stage-IV observations.
*CCAT-prime funding has been provided by Cornell University, the Fred M. Young Jr. Charitable Fund, the German Research Foundation through grant number INST 216/733-1 FUGG, the Univ. of Cologne, the Univ. of Bonn, the Max Planck Institute for Astrophysics, and the Canadian Atacama Telescope Consortium.
