The Michigan/Magellan Fiber System (M2FS):Basic Design Goals

• Develop a dedicated, optimized fiber-fed spectrograph to replace MIKE for multi-object, fiber-fed spectroscopy at Magellan;• Retain as much of MMFS consistent with the overall design goals;• Use large-format, high-QE CCDs (e.g. E2V 4k 4k, 15 m) to obtain full coverage of as many echelle orders as possible, and to achieve high instrument throughput;• Optimize in wavelength from about 390-900 nm;• Use short, broad-spectrum fibers to minimize fiber throughput losses;• Reduce internal reflections and scattered light, and provide sufficient fiber separation to map residual scattered light reaching the detectors;• Optimize cross-dispersion to the fiber separation;• Support a range of high resolution observing modes with target resolution of R~20000;• Introduce a low-resolution (R~1000) multi-fiber capability if possible at low cost;• Make M2FS simpler to operate, install, and maintain than MMFS.

The Michigan/Magellan Fiber System (M2FS):Sample Science Programs

• SkyMapper spectroscopic support. New dwarfs, halo streams.• Reverberation mapping of AGN in COSMOS fields.• Dark matter in globulars?• Weighing massive galaxies with GC systems.• Dynamical evolution of star forming regions. Binary stars in star forming regions.• Intermediate-mass BHs in x-ray emitting globular clusters. Surveys of x-ray sources around nearby massive galaxies.• Ultra low-metallicity stars in dwarf galaxies.• Survey of mass loss in evovled stars of globular clusters.• Outflows from young stars.• Mass to light ratios of compact systems in nearby galaxy clusters.

The NSF/MRI proposal acts as a de facto Conceptual Design Review. Two design reviews, one for fiber, optical and CCD design issues in late 2009, and one to review the final spectrograph design in mid 2010. Pre-ship reviews will be held prior to fiber/CCD shipment (Dec 2010) and spectrograph shipment (Oct 2011). A commissioning report to the SAC will be provided in early 2012. This is an aggressive schedule. The contingency is in the 36-month term of the MRI. This schedule above can extend to Aug 2012 and still fit in the funding period. No-cost extensions can allow the project to run into 2013.
