Mid-Infrared Array Camera for Astronomical Continuum and Line Imaging

该奖项将支持亚利桑那大学参与与亚利桑那大学、史密森天体物理天文台和海军研究实验室合作的中红外阵列相机的建造和天文学应用。该相机将使用休斯飞机公司20 x 64砷掺杂硅杂质带导混合阵列与电容跨阻放大器读出。该探测器特别适合在高背景通量地面观测条件下，在10和20um大气窗口提供高灵敏度。反射光学将提供衍射极限（0.7角秒/像素）和超分辨率（0.7角秒/像素）。34弧秒/像素)操作。相机电子和计算机提供高达5000帧/秒的操作，以防止在高滞后状态下检测饱和。最初的观测计划将集中于对银河系和其他星系中恒星形成区域的各种连续统和谱线观测。例如：低质量恒星的星周盘的热辐射，恒星形成区的激波气体，用NeII线成像的银河系中心的速度流，以及活动星系的核。

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.
