Abstract

The Gemini North Adaptive Optics (GNAO) facility is the upcoming Adaptive Optics (AO) facility for Gemini North providing a state-of-the-art AO system for surveys and time domain science in the era of James Webb Space Telescope (JWST) and Rubin operations. GNAO will be optimized to feed the Gemini Infrared Multi Object Spectrograph (GIRMOS). The GNAO project includes the development of a new laser guide star facility which will consist of four side launched laser beams supporting the two primary AO modes of GNAO: a wide-field mode providing an improved image quality over natural seeing for a 2-arcminute circular field-of-view using Ground Layer AO (GLAO) and a narrow-field mode providing near diffraction-limited performance over a 20 × 20 arcsecond square field-of-view using Laser Tomography AO (LTAO). After a competitive phase A study among three teams for the conceptual design of the AO bench, one team has been selected to complete the design, build and commissioning it at the telescope. We will be presenting the overall GNAO facility design, including specifics related to the AO bench and its architectural design. We will provide updates on all subsystems of the facility.
