摘要：

The Bark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the Universe Using the Baryon Acoustic Oscillation technique. The spectra of 40 million galaxies over 14000 sq deg will be measured during the life of the experiment. A new prime focus corrector for the KENO Mayall telescope will deliver light to 5000 fiber optic positioners. The fibers in turn feed ten broad-band spectrographs. We will describe the Fiber Systems design with specific emphasis on novel approaches and essential elements that lead to exceptional performance.
