Title: The DESI instrument control systems: status and early testing

Abstract

The Dark Energy Spectroscopic Instrument (DESI) is a new instrument currently under construction for the Mayall 4-m telescope at Kitt Peak National Observatory. It will consist of a wide-field optical corrector with a 3.2 degree diameter field of view, a focal plane with 5,000 robotically controlled fiber positioners and 10 fiber-fed broad-band spectrographs. The DESI Instrument Control System (ICS) coordinates fiber positioner operations, interfaces to the Mayall telescope control system, monitors operating conditions, reads out the 30 spectrograph CCDs and provides observer support and data quality monitoring. In this paper, we summarize the ICS design, review the current status of the project and present results from a multi-stage test plan that was developed to ensure the system is fully operational by the time the instrument arrives at the observatory in 2019.

The Dark Energy Spectrographic Instrument (DESI) Optical Fiber System

Technical Report Levi, Michael

The specific research of the DESI project is to study in detail the expansion history of the Universe over the past 10 billion years. In order to do this, the project designed, fabricated, tested and commissioned the DESI instrument which has been deployed at the Mayall Telescope at the Kitt Peak National Observatory near Tucson, Arizona. The DESI project was conducted by approximately 30 US and foreign national laboratories. The complete instrument includes a prime focus corrector assembly, a focal plane with 5,000 optical fibers whose position can be set by robotic positioners, and ten spectrographs. Each spectrograph can accommodatemore »« less

The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the universe using the baryon acoustic oscillations technique. The spectra of 35 million galaxies and quasars over 14,000 square degrees will be measured during a 5-year survey. A new prime focus corrector for the Mayall telescope at Kitt Peak National Observatory will deliver light to 5,000 individually targeted fiber-fed robotic positioners. The fibers in turn feed ten broadband multi-object spectrographs. We describe the ProtoDESI experiment, that was installed and commissionedmore »« less

DESI Focal Plane Assembly: Time-Lapse Video

Multimedia

This 56-second time-lapse video shows three different camera views of assembly work for the Dark Energy Spectroscopic Instrument’s Focal Plane. First, it shows the process of joining separate lengths of fiber-optic cables, known as fusion splicing. More than 5,000 fiber-optic cables, each measuring over 50 meters, will extend from near the top of the Mayall Telescope down to devices known as spectrographs that will be used to measure the properties of light from millions of distant galaxies. The Mayall Telescope is at Kitt Peak National Observatory near Tucson, Arizona. The middle portion of the video shows another view of themore »« less
