The changing magnetic field of the Sun causes powerful disturbances that affect orbiting satellites and life on Earth. Studying these magnetic-driven events on the Sun with ground-based telescopes requires wide-field image stability from Adaptive Optics (AO). AO is an important tool for solar astronomy because dynamic events on the Sun can cover a one arc-minute field of view simultaneously.AO is a method to correct telescope images for the distortion of light caused by its travel from outer space through the turbulent atmosphere. As a result of a previous award (AST-1407597), Goode and collaborators demonstrated such image correction for the first time in a wide-field with a solar telescope. Results were unveiled in a video display at the American Astronomical Society meeting in January 2017. The broad objectives outlined here are consistent with the Adaptive Optics roadmap, a community-developed white paper. This strategy document specifically called for further MCAO development work beyond these initial proof-of-concept experiments and quantitative performance analysis. This project builds upon prior research by implementing a turbulence profilometer -- a device to measure atmospheric turbulence throughout the observing season. Gathering such data will optimize future observations. This project will also implement another deformable mirror and a faster real-time control computer to enable 1-1.5 kHz operation. Developing this technology will enable critical observations to improve our understanding of the Sun and gain insights into the origins of potentially catastrophic space weather. This experimental technique will be essential to perfect for the upcoming Daniel K. Inouye Solar Telescope (DKIST).

不断变化的太阳磁场会引起强烈的扰动，影响轨道卫星和地球上的生命。 使用地面望远镜研究太阳上的这些磁驱动事件需要自适应光学（AO）的宽视场图像稳定性。 天文学是太阳天文学的重要工具，因为太阳上的动态事件可以同时覆盖一个角分的视场。天文学是一种校正望远镜图像的方法，用于校正来自外层空间的光通过湍流大气层造成的扭曲。 由于之前的奖项（AST-1407597），古德和合作者首次在太阳望远镜的宽视场中展示了这种图像校正。结果在2017年1月美国天文学会会议上的视频显示中公布。 这里概述的广泛目标与自适应光学路线图一致，这是一份社区开发的白色文件。 该战略文件特别要求在这些初步概念验证实验和定量性能分析之外进一步开展MCAO开发工作。 该项目以先前的研究为基础，安装了湍流轮廓仪-一种在整个观测季节测量大气湍流的装置。 收集这些数据将优化未来的观测。 该项目还将实现另一个可变形镜和一个更快的实时控制计算机，以实现1-1.5 kHz的操作。开发这项技术将使关键观测能够提高我们对太阳的理解，并深入了解潜在灾难性空间天气的起源。 这项实验技术将是必不可少的完美为即将到来的丹尼尔K。Inouye太阳望远镜（DKIST）。
