该奖项将支持亚利桑那大学的参与 在亚利桑那大学史密森尼分校的合作下， 天体物理观测站和美国海军研究实验室 中红外线天线阵的建造和天文用途 相机 这台相机将使用休斯飞机公司20 x 64 掺砷硅杂质带传导混合阵列 a电容跨阻抗放大器读数。 该检测器 特别适合于在两个方面提供高灵敏度， 高本底通量下的10和20 μ m大气窗口 地面观测条件。 反射光学器件将 提供衍射极限（0.7弧秒/像素）和 超分辨率（.34弧秒/像素）操作。 相机 电子设备和计算机提供高达5000的操作 帧/秒，以防止在高欠序时检测饱和。 最初的观测计划将集中在各种 星星形成区的连续谱线和谱线观测 在银河系和其他星系。 一些例子是：热 来自低质量恒星的星周盘的辐射，冲击气体 在星星形成区，速度在银河系中心流动 和活动星系的核心。

This award will support the University of Arizona participation in a collaboration of the University of Arizona, Smithsonian Astrophysical Observatory, and Naval Research Laboratory in the construction and astronomical use of a mid-infrared array camera. This camera will use a Hughes Aircraft Company 20 x 64 Arsenic Doped Silicon Impurity Band Conduction Hybrid Array with a Capacitance Transimpedances Amplifier readout. This detector is particularly suited to providing high sensitivity in both the 10 and 20um atmospheric windows under high background flux ground-based observing conditions. Reflective optics will provide both diffraction limited (0.7 arc seconds/pixel) and superresolution (.34 arc seconds/pixel) operation. The camera electronics and computer provide for operation up to 5000 frames/second to prevent detect saturation at high backorder. The initial observing program will focus on a variety of continuum and spectral line observations of star forming regions in the Milky Way and other galaxies. Some examples are: thermal emission from circumstellar disks of low-mass stars, shocked gas in star formation regions, velocity flows in the galactic center with NeII line imaging, and the nuclei of active galaxies.
