The BigBOSS dark energy experiment

The BigBOSS experiment is a project designed to unlock the mystery of dark energy using existing ground-based facilities operated by National Optical Astronomy Observatory (NOAO). A new 5000-fiber R=5000 spectrograph covering a 3-degree diameter field will measure clustering properties in the distribution of galaxies and hydrogen gas spanning redshifts from 0.2 < z <3.5. This project will enable an unprecedent multi-object spectroscopic capability. Details on our instrumentation development for BigBOSS will be given together with a short summary of the project.
