Purpose

CCAT is a groundbreaking submillimeter telescope that will be located at 5600 m altitude on Cerro Chajnantor in the Andes mountains of northern Chile. CCAT will combine high sensitivity, a wide field of view, and a broad wavelength range to provide an unprecedented capability for deep, large area multicolor submillimeter surveys. Science objectives include galaxy formation and evolution throughout the history of the Universe; the hot gas pervading clusters of galaxies; star formation, protoplanetary disks, and debris disks in the Milky Way galaxy; and Kuiper belt objects in the outer reaches of the Solar system. Instrumentation will include bolometer cameras, direct detection spectrometers, and heterodyne receiver arrays.
