Development of Superconductor-Insulator-Normal Metal Tunnel Junction Detectors for Large Submillimeter Arrays

AST-0505379/加州大学圣巴巴拉卢宾该奖项旨在设计、建造和表征以超导-绝缘体-普通金属隧道结作为微测辐射热计的大型探测器阵列。这些器件在300毫升或以下的温度下工作时，可以实现背景受限的灵敏度。这种器件也可以完全单片制造，不需要微机械加工。与其他技术相比，这代表了一个巨大的优势，因为制造和设计的简单性应该使千像素大小的阵列用于毫米和亚毫米光谱区域的目标成为可能。

AST-0505379/Lubin, UC Santa BarbaraThe award is to design, build, and characterize a large format detector array featuring Superconductor-Insulator-Normal metal tunnel junctions as microbolometers. These devices can achieve background-limited sensitivity while operating at a temperature at or below 300 millikelvin. The devices can also be fabricated completely monolithically with no micromachining. This represents a great advantage over other technologies in that the simplicity of fabrication and design should make feasible the goal of kilo-pixel size arrays for use in the millimeter and submillimeter region of the spectrum.
