SUMMARY:Workshop / Seminar:HEP-Astro Seminar |  Redshifts by Breakfast but what is for lunch? From DESI to Stage-5 Spectroscopy
DESCRIPTION:The Dark Energy Spectroscopic Instrument (DESI) is an ultra-efficient multi-object spectrograph installed on the Mayall telescope. DESI routinely collects spectra from ~2 million objects per month\, and delivers nightly redshifts in time for morning coffee. The DESI survey is now more than 60% complete\, and so planning for future campaigns is beginning in earnest. I will describe the DESI \"Stage-4\" experiment\, with a focus on how the design of the DESI instrument enables the survey to study dark energy. I will then present a proposal for an upgraded \"DESI-2\" survey\, which would\, in part\, survey higher-redshift sources to probe early dark energy and the growth of structure in the matter-dominated regime. Finally\, I will detail requirements to achieve a \"Stage-5\" experiment\, which could be met by upgrading the Mayall and Blanco telescopes and installing augmented DESI-type devices at each of these facilities. I will outline proposed designs for such instruments\, and the path towards realizing these designs!
