论文摘要

双子座北部自适应光学(GNAO)设施是双子座北部即将到来的AO设施,为JWST和Rubin操作时代提供了最先进的AO系统,用于调查和时域科学。 GNAO将被优化以喂养双子红外多物体光谱仪(GIRMOS)。虽然Girmos是定义GNAO功能的主要科学驱动力,但使用GNAO部署了任何带有f/32梁的仪器。 GNAO项目包括开发新的激光导恒星设施,该设施将由四个侧面推出的激光束组成,支持GNAO的两种主要AO模式:一种宽视场模式,可提供比自然景观的改进图像质量,以提供2个圆形圆形圆形视野范围内的2次圆形领域模式,并提供了几乎差异场模式,并提供了差异范围的范围。 GNAO宽场模式将实现Girmos的多IFU配置,其中将对每个人IFU进行科学光束,并在Girmos中使用多对象AO进行校正。 GNAO窄场模式将馈送Girmos瓷砖IFU配置,其中所有IFU都合并为场中央的“超级” -IFU。 GNAO还包括开发新的实时控制器,一个新的GNAO设施系统控制器,最后是新的AO基准的开发。我们在本文中介绍了GNAO设施的概述,并提供了每种产品的状态更新。

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.
