Left is the side view of an all-refractive system that is modified slightly from the working AO system of the current 65-cm telescope: the pupil is first imaged onto the tip/tilt mirror by the lens L1. The solar image is then collimated and the telescope pupil is re-imaged again onto the DM by Lenses L2 and L3. Finally, at the AO output, a real solar image is formed by another lens, which could be fed to science instruments. Right is a new design, i.e., a largely reflective system. Lenses after L2 are now replaced by mirrors. }}{11}} \newlabel{FIG08}{{8}{11}} \@writefile{toc}{\contentsline {subsubsection}{\numberline {A.3.4}Electronic, Computing and Mechanics Systems}{12}} \@writefile{toc}{\contentsline {subsubsection}{\numberline {A.3.5}Setup, Testing and Observations of the New AO System}{12}} \@writefile{lof}{\contentsline {figure}{\numberline {9}{\ignorespaces example}}{13}} \newlabel{fig09}{{9}{13}} \@writefile{toc}{\contentsline {subsection}{\numberline {A.4}Relationship to Future Work and Nighttime Astronomy}{14}} \@writefile{toc}{\contentsline {subsubsection}{\numberline {A.4.1}Higher Order Solar AO in the Future}{14}} \@writefile{toc}{\contentsline {subsubsection}{\numberline {A.4.2}Multi-Conjugate AO}{15}} \@writefile{toc}{\contentsline {section}{\numberline {B}Education and Research Training}{15}} \@writefile{toc}{\contentsline {section}{\numberline {C}Personnel and Management}{15}} \@writefile{toc}{\contentsline {section}{\numberline {D}References}{16}}
