Widefield Upgrade for the Spartan Infrared Camera

密歇根州立大学正在建造斯巴达相机，用于智利的2.5米高空望远镜。斯巴达相机将由四个2048x2048探测器组成矩阵，覆盖0.16角秒分辨率的5‘x 5’视野(或0.08角秒分辨率的一半视野)。正在建设中的斯巴达相机将只由一个半填充的探测器矩阵(2个探测器)组成，其中只有一个探测器是科学级的。申请的拨款将用于部分匹配的资金，为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Sauar合作伙伴。一旦完成并安装在Soar望远镜上，斯巴达相机将使从银河系到高红移物体的各种近红外科学成像成为可能。SOAR仪器对天文学有着广泛的影响，因为它是美国和外国机构之间的广泛合作。

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.
