Investigation of Superconducting Fabrication Techniques, Materials, and Mixer Circuits for Astronomical Receivers

这项工作将提高实验室在严格控制的条件下使用新材料制造超导外差混频器元件的能力。弗吉尼亚大学的这个实验室是美国两个专门研究射电天文学超导设备的实验室之一， 该奖项将允许对设施进行现代化改进。 在过去几年中，该实验室为阿尔马3和6波段生产了3毫米和1毫米混频器，为Taeduk射电天文台生产了2毫米设备;此外，它正在与马萨诸塞州大学和亚利桑那大学合作设计新的热电子测辐射热计设备。

This work will upgrade laboratory capabilities for use of new materials under carefully controlled conditions for fabricating superconducting heterodyne mixer elements. This University of Virginia laboratory is one of two in the country that specializes in superconducting devices for radio astronomy, and the award will allow modernizing improvements to the facility. Over the past few years the lab has produced 3mm and 1mm mixers for ALMA bands 3 and 6, and 2mm devices for the Taeduk Radio Observatory; in addition, it is collaborating with the University of Massachusetts and the University of Arizona on the design of new hot electron bolometer devices.
