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

JanesMRI 007954摘要将开发一种用于帕金斯72英寸望远镜的多功能仪器（PRISM），该望远镜位于弗拉格斯塔夫以南的安德森梅萨，由洛厄尔天文台与波士顿大学合作运营。 自从俄亥俄州退出“拥有”这架望远镜的财团以来，这架望远镜目前没有仪器。该棱镜仪器将提供宽视场成像、偏振测量和低色散多目标光谱学，该系统将采用大幅面（2048x2048）、15微米像素Loral CCD焦平面。 在这个1.83米望远镜上的宽视场成像将覆盖13.6 x 13.6弧分的视场，在整个0.32到1的范围内具有0.4弧秒像素。微米波长范围。 中等分辨率的棱镜光谱仪将覆盖相同的光谱范围，光谱分辨率约为1000。线性成像偏振法将覆盖90平方弧分视场，增量偏振低于0.05%，跨越0.32至1微米波长带。***

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. ***
