ABSTRACTThis grant will be used to replace the red and blue channel cameras on the Double Imaging Spectrograph (DIS) of the 3.5 meter telescope at the Apache Point Observatory. The detectors in the present cameras are outdated, having high noise, 12 to 40 electrons per pixel versus approximately 5 electrons per pixel for the new detectors, cosmetic defects, and low quantum efficiency. The replacement devices will be larger, 1048 x 1320 pixels versus 512 x 512 for the present blue channel camera and 800 x 800 pixels for the red channel camera, and provide a smaller plate-scale for the telescope.

摘要这笔赠款将用于更换阿帕奇角天文台3.5米望远镜的双成像光谱仪（DIS）上的红色和蓝色通道相机。 目前的相机中的检测器是过时的，具有高噪声，每像素12至40个电子，而新检测器每像素约5个电子，外观缺陷和低量子效率。 更换后的设备将更大，为1048 x 1320像素，而目前的蓝色通道相机为512 x 512像素，红色通道相机为800 x 800像素，并为望远镜提供更小的底片比例。
