SUMMARY:The Dark Energy Spectroscopic Instrument (DESI)
DESCRIPTION:The Dark Energy Spectroscopic Instrument (DESI)\nProf. Francisc
 o Prada\n\nDESI is a massively multiplexed fiber-fed spectrograph that wil
 l make the nextmajor advance in dark energy in the timeframe 2018-2022. On
  the Mayalltelescope, DESI will obtain spectra and redshifts for tens of m
 illions ofgalaxies and cuasars with 5,000 fiber postioner robots, construc
 ting a3-dimensional map spanning the nearby universe to 10 billion light y
 ears. DESIis supported by the US Department of Energy Office of Scien
 ce to perform thisStage IV dark energy measurement using baryon acoustic o
 scillations and othertechniques that rely on spectroscopic measurements. S
 pain has a major role inDESI with the construction of the Focal Plate and 
 the development of the fiberpositioners. I will give an overview of the DE
 SI science, instrument, and Spainparticipation in the project.
