The Cerro Chajnantor Atacama Telescope (CCAT) is a proposed 25 metres (82 ft) telescope that is intended to reveal the cosmic origins of stars, planets, and galaxies with its submillimeter cameras and spectrometers enabled by superconducting detector arrays.[1][2] The telescope was originally called the Cornell Caltech Atacama Telescope.
The collaboration is building a smaller 6 metre submillimeter/millimeter telescope, the CCAT-prime (CCAT-p) as a first step before pursuing the 25 metre CCAT at some (unknown) time in the future. CCAT-p will be located at the same site and share similar mission as the full sized CCAT, but naturally with reduced capabilities compared to the CCAT.
Site
The planned site is at an altitude of 5,612 metres (18,412 ft), on Cerro Chajnantor of the volcanic Purico Complex, in the Atacama Desert of northern Chile. CCAT would be one of the highest permanent, ground-based telescopes in the world.[3]
Description
Submillimeter is a type of microwave radiation that is closest to infrared in the light spectrum. The telescope is to be outfitted with a wide-field camera that is expected to map the sky 1000 times faster and with better resolution than the SCUBA-2 camera installed on the James Clerk Maxwell Telescope in Hawaii.[4]
Construction
The CCAT consortium participating in the project includes: Cornell University; Associated Universities, Inc., University of Colorado at Boulder, University of Cologne, University of Bonn, University of British Columbia, and other universities in the U.S. and Canada. [5][4]
Construction was at one time projected to begin in 2015. The telescope is intended to complement the Atacama Large Millimeter Array (ALMA), by discovering new sources that ALMA will follow up with highly detailed imagery.[6]
In January 2014 the Chilean government granted the use of land on Cerro Chajnantor to the CCAT consortium for the telescope and the road to the mountain summit. [7] Also in January 2014, the Atacama Astronomy Park was inaugurated by the Chilean government, to coordinate activities between the current and upcoming observatories in the Chajnantor region. [8]
The project has had trouble finding funding, and construction of CCAT has not materialized (as of 2019).[9]
The CCAT-p telescope construction started 2017 (signing of construction contract) with first light expected 2021.[10] The fabrication of telescope components started late 2018.[11]
