Description

The Dark Energy Spectroscopic Instrument (DESI) is a Stage IV dark energy experiment under construction to measure the expansion history of the Universe using baryon acoustic oscillations (BAO) and the growth of structure using redshift-space distortions (RSD). With 5000 robotically-actuated fibre positioners, the 5-year redshift survey will map 35 million galaxies and quasars and place new constraints on many cosmological parameters concerning dark energy, modified gravity, inflation, and neutrinos. I will describe and provide a status update on the DESI focal plane system, which has been built at multiple institutions, integrated at LBNL, and is ready for final installation at Kitt Peak National Observatory (KPNO).
