9 August 2016 Optical fiber termination method for the Dark Energy Spectroscopic Instrument (DESI)
Author Affiliations +
The Dark 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 KPNO Mayall telescope will deliver light to 5000 fiber optic positioners. The fibers in turn feed ten broad-band spectrographs. We will describe the method we use to optically terminate the fibers which offers many advantages over methods that have been used in the past.
