This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project is for the design and construction of a sideband-separating Superconductor-Insulator-Superconductor mixer receiver for the 380 to 500 GHz band. The receiver, whose design will mimic that used for the Atacama Large Millimeter/submillimeter Array (ALMA) 210 to 275 GHz receiver developed by the National Radio Astronomy Observatory, would be deployed on the Arizona Radio Observatory's Sub-Millimeter Telescope on Mt. Graham, Arizona. The receiver would be used to study known molecular spectral lines in this region, as well as likely discover many new ones. The advantage of this design over the ALMA design is that the balanced system allows the use of much lower local oscillator power, which can be important in some instances (such as array feeds, for example) where sufficient local oscillator power is difficult to achieve.

该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。该项目用于设计和构建侧带分开的超导体 - 启发器 - 渗透器搅拌器接收器，用于380至500 GHz频段。接收器的设计将模仿用于Atacama大毫米/亚毫米阵列（ALMA）210至275 GHz接收器由国家射电天文台开发的，将部署在亚利桑那州格拉厄姆山上的亚利桑那射电天文台的亚利桑那州射电视台的亚毫米型望远镜上。接收器将用于研究该区域的已知分子光谱线，并可能发现许多新的分子光谱线。这种设计比ALMA设计的优点在于，平衡系统允许使用较低的本地振荡器功率，在某些情况下（例如，阵列提要）很难实现足够的本地振荡器功率，这在某些情况下可能很重要。
