The Cerro Chajnantor Atacama Telescope (CCAT) Project: Design of the Telescope and its Enclosure

Cerro Chajnantor阿塔卡马望远镜(CCAT)计划是一个25米长的望远镜，工作波长从毫米到短亚毫米，位于智利北部靠近阿塔卡马大毫米/亚毫米阵列(ALMA)的地方。在海拔18,500英尺的高度，望远镜将利用异常干燥的空气进行高频观测。包含先进探测器阵列的仪器将利用望远镜的大视场来测量大片天空，以探测丰富的高红移星系，成像附近的星系和分子云，并发现和研究太阳系天体。CCAT是在国家科学院被召唤的吗？2010年天体十年调查被认为是十年最优先的中型项目。CCAT将是一种公私伙伴关系，来自康奈尔大学、加州理工学院、科罗拉多大学、加拿大大学财团、德国波恩大学和科隆大学以及潜在的其他国内外合作伙伴的大量机构和私人投资。Astro2010估计CCAT的总建设成本为1.4亿美元(联邦投资为3700万美元)，年度运营成本为1100万美元(750万联邦投资)。该项目利用机构和私人资金为大西洋金枪鱼养护委制定了一个概念设计。通过这项奖励获得的资金将把望远镜及其外壳的设计和开发推进到施工就绪的水平。大西洋金枪鱼养护委的合作伙伴打算提供持续的机构捐助，使项目的所有其他要素达到可比的设计成熟度水平。

The Cerro Chajnantor Atacama Telescope (CCAT) is planned as a 25-meter telescope operating at millimeter to short sub-millimeter wavelengths and located in northern Chile close to the site of the Atacama Large Millimeter/submillimeter Array (ALMA). At an elevation of 18,500 feet the telescope would take advantage of the exceptionally dry air for high frequency observations. Instrumentation containing advanced detector arrays would exploit the telescope's large field of view for surveying wide areas of sky to detect an abundance of high redshift galaxies, to image nearby galaxies and molecular clouds and to discover and study Solar System bodies. CCAT was called out in the National Academies? Astro2010 Decadal Survey as the highest priority medium-scale project for the decade. CCAT would be a public-private partnership with significant institutional and private investments from Cornell University, the California Institute of Technology, the University of Colorado, a consortium of Canadian universities, the German universities of Bonn and Cologne and potentially other domestic and foreign partners. Astro2010 estimated the total construction cost of CCAT to be $140 million ($37 million as the Federal investment) and annual operating costs of $11 million ($7.5 million Federal). The project has developed a conceptual design for CCAT using institutional and private funds. Funding through this award advances the design and development of the telescope and its enclosure to the level of construction readiness. The CCAT partners intend to provide ongoing institutional contributions to move all other elements of the project to a comparable level of design maturity.
