我们描述了正在建设中的密歇根/麦哲伦光纤系统(M2FS)，用于麦哲伦/克莱望远镜。M2FS由四个主要部件组成，包括：(1)光纤馈送双光谱仪(MSpec)，其中每个光谱仪由128根光纤馈送(总的多路复用系数为256)，每台光谱仪的工作波长优化为370-950 nm；(2)光纤安装系统(MFib)，它在f/11 Nasmyth望远镜焦面支撑光纤和光纤插板，并将光纤组织成‘鞋’，用于将光纤放置在MSpec光谱仪的成像面；(3)新的广场校正器(WFC)，在30角分直径的视场上产生高质量的图像；(4)安装在望远镜次级附近的单元(MCal)，用于提供波长和连续谱校准，并支持新型自动光纤识别系统中的关键组件。我们描述了M2FS的光学机械特性、其工作模式和预期性能，以及潜在的升级，包括开发机器人光纤定位器和大气色散校正器。我们描述了M2FS设计如何作为强大的广域、大规模多路复用光谱测量设施的基础。
We describe the Michigan/Magellan Fiber System (M2FS) under construction for use on the Magellan/Clay telescope. M2FS consists of four primary components including: (1) A fiber-fed double spectrograph (MSPec) in which each spectrograph is fed by 128 fibers (for a total multiplexing factor of 256) and each is optimized in to operate from 370- 950 nm; (2) A fiber mounting system (MFib) that supports the fibers and fiber plug plates at the telescope f/11 Nasmyth focal surface and organizes the fibers into ‘shoes’ that are used to place the fibers at the image surface of the MSpec spectrographs;, (3) A new wide-field corrector (WFC) that produces high-quality images over a 30 arcmin diameter field; (4) A unit (MCal) mounted near the telescope secondary that provides wavelength and continuum calibration and that supports a key component in a novel automated fiber identification system. We describe the opto-mechanical properties of M2FS, its modes of operation, and its anticipated performance, as well as potential upgrades including the development of a robotic fiber positioner and an atmospheric dispersion corrector. We describe how the M2FS design could serve as the basis of a powerful wide-field, massively multiplexed spectroscopic survey facility.
