A Preliminary Design for the GMT-Consortium Large Earth Finder (G-CLEF)
The GMT-Consortium Large Earth Finder (G-CLEF) is an optical band echelle spectrograph that has been selected as the first light instrument for the Giant Magellan Telescope (GMT). G-CLEF is a general purpose, high dispersion instrument that is fiber fed and capable of extremely precise radial velocity measurements. G-CLEF has undergone science requirements review and instrument requirements review and will be the subject of a preliminary design review in early 2015. Here we describe design and system engineering innovations that have arisen in response to the review process. We present a top-level description of G-CLEF capabilities, functionality and major subsystems.
