Abstract

The planned construction and completion of the Large Synoptic Survey Telescope (LSST) Project consists of phased activities. The initial telescope construction period will transition to a multi-year commissioning phase, which will conclude with final hand off to science operations. The initial telescope alignment will utilize laser tracker fiducials and nodal aberration theory (NAT) to demonstrate Engineering First Light with a three-mirror optical system and test camera, prior to the integration of the science camera. This plan exploits the diffraction limited on-axis image quality of the three-mirror design. Commissioning consists of final integration of the three LSST subsystems (Telescope, Camera, and Data Management), followed by on-sky science verification to show compliance with the survey performance specifications.
