CCAT will be a 25 m telescope for submillimeter astronomy located at
5600 m altitude on Cerro Chajnantor in 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.
