AIRO: The Antarctic Infrared Observatory

最初的提案寻求资金来建设南极红外天文台(AIRO)，这是一台将部署在南极的直径为2米的新红外望远镜。南极洲为地面红外天文提供了独特的低热背景。南极洲的红外望远镜只需要一个中等的口径就可以达到非凡的灵敏度。AIRO打算利用这些独特的条件来测量红外天空并进行时间监测研究。然而，AIRO目前缺乏该望远镜及其拟议的第一台仪器--2色(K L和K M波段)广域成像相机的详细概念设计。开发这样的设计对Airo的成功至关重要。该设计将从科学要求出发，最大限度地从低南极热背景中获得科学回报。在修订工作所涉期间，提出者将(1)确定望远镜和相机的详细科学要求，(2)制定红外相机的光学和机械概念设计，(3)制定望远镜的光学概念设计，以及(4)获得相机和望远镜的可靠成本估算。这项工程研究将提高在南极洲建造整个望远镜的安全裕度并降低风险。此外，对技术和科学需求进行更切合实际的评估将产生更准确的费用估计。

The original proposal seeks funding to build an Antarctic Infrared Observatory (AIRO), a new 2-m diameter infrared telescope to be deployed at the South Pole. Antarctica provides a uniquely low thermal background for ground-based infrared astronomy. With only a modest aperture an infrared telescope in Antarctica can achieve extraordinary sensitivity. AIRO intends to exploit these unique conditions surveying the infrared sky and performing temporal monitoring studies. However, AIRO currently lacks a detailed conceptual design for the telescope and for its proposed first instrument, a 2 color (K + L, and K + M band) wide-field imaging camera. Developing such a design is critical to AIRO's success. The design will flow from the scientific requirements that maximize the scientific return from the low Antarctic thermal backgrounds. During the period covered by the revised effort, the proposers will (1) establish the detailed scientific requirements for the telescope and camera, (2) develop a conceptual optical and mechanical design for the infrared camera, (3) develop a conceptual optical design for the telescope, and (4) obtain robust cost estimates for the camera and telescope. This engineering study will increase the safety margin and mitigate risk in building the entire telescope in Antarctica. Moreover, a more realistic assessment of the technical and scientific requirements will result in a more accurate cost estimate.
