The CCAT Sub-millimeter Telescope Project in the Chilean Andes

Eduardo Hardy (AUI Chile)

CCAT is a 25m diameter submillimeter telescope to be located at 5600 m altitude on Cerro Chajnantor above the ALMA plateau. CCAT main characteristics are high sensitivity, a wide field of view, and a broad wavelength range to provide an unprecedented capability for deep, large area (up to 1 sq. degree) multicolor submillimeter surveys. In this, CCAT is, among other things, the perfect complement to the exceptional image resolution ALMA offers on the same spectral range but over small fields of view. A description of the science objectives, panoramic detector technologies (which include bolometer cameras, direct detection spectrometers, and heterodyne receiver arrays), as well as the construction challenges at such high altitude will be presented.
