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

AST-0505379/Lubin，加州大学圣巴巴拉分校该奖项是设计，建造和表征一个大型探测器阵列，其特点是超导体-绝缘体-普通金属隧道结作为微测辐射热计。这些器件可以在300毫开尔文或以下的温度下工作时实现背景限制灵敏度。该器件也可以完全单片地制造而无需微机械加工。这代表了比其他技术更大的优势，因为制造和设计的简单性应该使用于频谱的毫米和亚毫米区域的千像素尺寸阵列的目标变得可行。

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.
