A Wide Field, All-Refracting Spectrograph for the Hale 200-inch Prime Focus

作为为帕洛马天文台200英寸黑尔望远镜提供仪器的协议的一部分，卡内基天文台建造了一个大画幅CCD相机，用于在定焦处直接成像。该仪器，COSMIC，包括一个完整的安装底座和计算机控制系统。该奖项将提供配套资金，用于建造将添加到相机中的摄谱仪的光学和机械部件。摄谱仪将是一个低到中等分辨率，全传输摄谱仪，具有广泛的视野。它的主要科学用途之一将是获得高红移星系的光谱，以研究星系的演化。

As part of an agreement to provide instrumentation for the 200-inch Hale telescope at Palomar Observatory, Carnegie Observatories has constructed a large-format CCD camera for direct imaging at prime focus. The instrument, COSMIC, includes a complete mounting base and computer control system. This award will provide matching funds to construct the optical and mechanical components of a spectrograph to be added to the camera. The spectrograph will be a low to moderate resolution, all transmitting spectrograph with a wide field of view. One of its primary scientific uses will be to obtain spectra of galaxies at high redshift to study galaxy evolution.
