AB: The ATST is a 4-m aperture, off-axis solar telescope with integrated adaptive optics, low-scattered light, infrared, coronagraphic, and polarimetric capabilities. We present an overview of the ATST design. The ATST design has progressed in to the point where the project is ready to lead contracts for construction of major subsystems. These subsystems include the enclosure, the telescope mount assembly, and the primary and secondary mirror assemblies. We summarize the design concepts of the major telescope components. Thermal control of telescope structure and optical components to ambient temperature has been a major design focus. Where applicable, the conditions at the selected site, Haleakala, have been worked into the designs. The design of the wavefront control system that integrates telescope alignment functions, active control of the primary and high order adaptive optics will be summarized. A vigorous systems engineering approach has been implemented to ensure that the telescope will deliver the diffraction limited imaging performance specified in the Science Requirements Document.
