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.
