Abstract

The Herzberg Institute of Astrophysics was recently selected by the Gemini Observatory as one of the three competing organizations to conduct a conceptual design study for a new Gemini High-Resolution Optical Spectrograph (GHOS). This paper outlines the main features of the mechanical design, including the Cassegrain-mounted science input unit, the bench-mounted spectrograph and the fiber relay system. Topics include the design challenges associated with multiobject fiber relays in the science unit, environmental stability of the spectrograph bench and routing and handling of fibers in the Gemini dome environment.
