Summary: | The Gemini North Adaptive Optics (GNAO) facility is the upcoming AO facility
for Gemini North providing a state-of-the-art AO system for surveys and time
domain science in the era of JWST and Rubin operations.
GNAO will be optimized to feed the Gemini infrared Multi Object Spectrograph
(GIRMOS). While GIRMOS is the primary science driver for defining the
capabilities of GNAO, any instrument operating with an f/32 beam can be
deployed using GNAO.
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 and a narrow-field mode
providing near diffraction-limited performance over a 20x20 arcsecond square
field-of-view. The GNAO wide field mode will enable GIRMOS's multi-IFU
configuration in which the science beam to each individual IFU will be
additionally corrected using multi-object AO within GIRMOS. The GNAO narrow
field mode will feed the GIRMOS tiled IFU configuration in which all IFUs are
combined into a "super"-IFU in the center of the field.
GNAO also includes the development of a new Real Time Controller, a new GNAO
Facility System Controller and finally the development of a new AO Bench. We
present in this paper an overview of the GNAO facility and provide a status
update of each product. |
