Title: As-built new Mayall telescope top end for the DESI project

Abstract

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 35 million galaxies and quasars 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 ber optic positioners. The bers in turn feed ten broad- band spectrographs. We will present an overview of the mechanical structure that sits atop the Mayall Serrurier trusses and supports the six lenses, the Atmospheric Dispersion Compensator (ADC) rotator and the Focal Plane Assembly. Furthermore, this mechanical structure has already been built, we will describe the main technical requirements and challenges during the construction.

Installation of the Dark Energy Spectroscopic Instrument at the Mayall 4-meter telescope

Conference Besuner, Robert ; et al. - Proc.SPIE Int.Soc.Opt.Eng.

The Dark Energy Spectroscopic Instrument (DESI) is a Stage IV ground-based dark energy experiment that will measure the expansion history of the Universe using the Baryon Acoustic Oscillation technique. The spectra of 35 million galaxies and quasars over 14000 square degrees will be measured during the life of the experiment. We describe the installation of the major elements of the instrument at the Mayall 4m telescope, completed in late 2019. The previous prime focus corrector, spider vanes, and upper rings were removed from the Mayall’s Serrurier truss and replaced with the newlyconstructed DESI ring, vanes, cage, hexapod, and optical corrector.more »« less
