The Gemini Observatory is currently in the process of developing a Adaptive Optics facility for the Gemini North Telescope. A key part of this facility will be a redesign of the current Laser Guide Star Facility (LGSF) to a new facility that will allow for the creation of multiple laser beacons.
Gemini Observatory has been awarded a major funding from the National Science Foundation to build a complete new state of the art multi-conjugate adaptive optics system for Gemini North. The system will be designed to provide an MCAO facility delivering close to diffraction limit correction in the near-infrared over a 2 arcminutes field of view and feed imaging and spectroscopic instruments. We present in this paper the results of the conceptual design phase with details on the new proposed laser guide star facilities and adaptive optics bench. We will present results on the performance simulation assessments as well as the developed selected science cases.
