WegnerMRI0079523AbstractAn upgrade of the infrared detector for the Ohio State University-NOAO infrared imaging spectrometer (ONIS) at the 2.4-meter telescope at Kitt Peak National Observatory will be implemented. This has been a very productive instrument for astronomical research. The MDM Consortium, Inc operates the telescope, which is a consortium of Dartmouth College (1/3) and Ohio State University, Columbia University and the University of Michigan. In addition to doubling the field of view and wavelength coverage of the instrument, this upgrade eliminates serious cosmetic effect errors in the current system that causes calibration errors. The current detector will be replaced by an improved 1024x1024 pixel large format Raytheon InSb focal plane for use in the 1 to 3 micrometer wavelength region. The scientific research areas planned are wide-field surveys for extremely red objects (ERO's), infrared studies of globular cluster ages and infrared studies of supernovae. ***

WegnerMRI0079523摘要将对基特峰国家天文台2.4米望远镜的俄亥俄州立大学NOAO红外成像光谱仪(ONIS)的红外探测器进行升级。对于天文研究来说，这是一个非常有成效的仪器。该望远镜是由达特茅斯学院(1/3)、俄亥俄州立大学、哥伦比亚大学和密歇根大学组成的联盟。除了将仪器的视场和波长覆盖范围扩大一倍外，此次升级还消除了当前系统中导致校准误差的严重美容效应误差。目前的探测器将被改进的1024x1024像素大幅面雷神InSb焦平面取代，用于1至3微米波长区域。计划的科学研究领域包括对极端红色天体(ERO)的大范围调查、球状星团年龄的红外研究和超新星的红外研究。***
