A preliminary rendering of the CCAT-prime telescope.

CCAT-prime will be a 6-meter diameter telescope operating at submillimeter to millimeter wavelengths, with a mirror surface accuracy of 10 microns. The novel crossed-Dragone optical design will deliver a high-throughput wide-field-of-view telescope capable of illuminating >100,000 (sub)millimeter wavelength detectors so that large areas of the sky can be scanned rapidly.

The telescope is being designed and built by Vertex Antennentechnik GmbH. It will be roughly 12 meters tall, 23 meters wide, 8 meters deep, and weigh 200 metric tons. First light is expected in mid-2021.

View from the summit.

CCAT-prime will be located near the summit of Cerro Chajnantor in the Atacama Desert in Chile. The extremely high elevation (5600 meters) will allow observation of most northern and southern skies through all seasons due to the extremely dry atmosphere.

The CCAT consortium is a partnership of Cornell University, the Universities of Cologne and Bonn in Germany and CATC, a consortium of 10 Canadian academic institutions.
