Installation phase of next-generation dark energy experiment begins

Press release

Installation has begun for the Dark Energy Spectroscopic Instrument, a next-generation astrophysics tool. Fermilab is managing key parts of the construction of the instrument, which will begin its five-year observation run in 2019.

Powerful survey instruments help us map the sky with incredible precision. But what ensures that the instruments themselves are precisely built?

3-D galaxy-mapping project enters construction phase

From Berkeley Lab, Aug. 9, 2016: DESI, the Dark Energy Spectroscopic Instrument, will measure light from 35 million galaxies to provide new clues about dark energy. Fermilab is a collaborator on the Berkeley Lab project.
