Widefield Upgrade for the Spartan Infrared Camera

斯巴达相机是由密歇根州立大学建造的，用于智利的2.5米SOAR望远镜。斯巴达相机将由四个2048 × 2048的探测器组成，覆盖5‘ x 5’的视场，分辨率为0.16角秒（或一半的视场，分辨率为0.08角秒）。目前正在建造的斯巴达相机将只由一半的探测器矩阵（2个探测器）组成，其中只有一个探测器是科学级的。所要求的赠款将用于部分匹配资金，以为该相机再购买两个科学级探测器。这些探测器的大部分资金将来自巴西的SOAR合作伙伴。斯巴达相机一旦完成并安装在SOAR望远镜上，将能够对从银河系到高红移物体的各种目标进行近红外科学成像。SOAR仪器对天文学界有着广泛的影响，因为它是美国和外国机构之间广泛合作的产物。

The Spartan Camera is being built by Michigan State University for use on the 2.5 m SOAR telescope in Chile. The Spartan camera will consist of a matrix of four 2048x2048 detectors covering a field of 5' x 5' at a resolution of 0.16 arc seconds (or half that field with 0.08 arc second resolution). The Spartan camera under construction now will only consist of a half-populated detector matrix (2 detectors), with only one of the detectors being science-grade. The requested grant will be used for partially-matching funds to acquire two more science-grade detectors for the camera. The majority of the funding for these detectors will come from the Brazilian SOAR partner. The Spartan camera, once completed and installed on the SOAR telescope, will enable a variety of near-IR scientific imaging of targets ranging from Galactic to high-redshift objects. The SOAR instrument has a broad impact to the astronomical community, as it is a collaboration between a wide range of U.S. and foreign institutions.
