Development of the Perkins ReImaging SysteM (PRISM) at Boston University for Astronomical Studies

1月MRI007954摘要将为位于弗拉格斯塔夫以南安德森台地的珀金斯72英寸望远镜开发通用仪器(PRISM)，由洛厄尔天文台与波士顿大学合作运营。由于俄亥俄州立大学退出了拥有该望远镜的财团，该望远镜目前没有仪器。这台棱镜仪器将提供广视场成像、偏振测量和低色散多目标光谱。该系统将采用大幅面(2048x2048)、15微米像素的劳拉CCD焦平面。这个1.83米望远镜上的广域成像将覆盖13.6 x 13.6角分的视场，在整个0.32到1微米的波长范围内，0.4角秒的像素。中等分辨率的格栅光谱仪将覆盖相同的光谱范围，光谱分辨率约为1000。线性成像偏振测量将覆盖0.32到1微米波长范围内的90平方角分钟视场，偏振增量低于0.05%。***

JanesMRI007954AbstractA versatile instrument (PRISM) for the Perkins 72-inch telescope located on Anderson Mesa south of Flagstaff and operated by Lowell Observatory in Collaboration with Boston University will be developed. The telescope currently has no instruments since Ohio State has pulled out of the consortium which "owns" this telescope. This prism instrument will provide for wide-field imaging, polarimetry and low dispersion multi-object spectroscopy.The system will employ a large format (2048x2048), 15-micron pixel Loral CCD focal plane. Wide-field imaging on this 1.83-meter telescope will cover a 13.6 x 13.6 arcminutes field of view with 0.4 arcsecond pixels across the entire 0.32 to 1. Micron wavelength range. The moderate resolution grism spectrometer will cover the same spectral range with a spectral resolving power of approximately 1,000. Linear imaging polarimetry will cover 90 square arc-minute field of view with incremental polarization below 0.05%, across the 0.32 to 1-micrometer wavelength band. ***
