    2. Before We Begin Purpose of this meeting is not a design review Examples to be shown were developed to help evaluate and narrow selection of the enclosure type After enclosure type is selected: Design features and specifications to be worked out in detail Developed concept to be presented at CoDR Manufacturers (at CoDR) to be involved in next phase of costing, design evaluation & refinement The meeting today is a workshop Discussion key!

    3. Two major types of enclosures considered for ATST: Rotating: Non-CoRotating (e.g., Keck, Gemini, WIYN) CoRotating (e.g., Subaru, LBT, MMT) CLEAR-Style Retractable: Collapsible (e.g., Starfire, AEOS) Clamshell (e.g, Faulkes, KPVT, DOT) Roll-Off (e.g., Sloan Digital Survey) Two most promising examples selected for closer examination and to help focus the studies and analyses: Hybrid Rotating Collapsible-type Retractable 2 Enclosure Types or To Dome, or not to Dome

    4. To Dome, or not to Dome continued

    5. Rotating Enclosure: Hybrid (cross between corotating and non-corotating)

    6. Retractable Enclosure: Tin Cup (manufacturers choice for retractable at this scale)

    7. Enclosure Concepts (cont.)

    8. Highest Priority Trades, Studies Telescope Protection & Performance Enclosure Shell Seeing (Exterior) Interior, Structure Seeing Wind Effects (Wind Shake, Mirror Buffeting) Scattered and Stray Light Control Cost and Technical Risk

    9. Second-Level Trades Handling and Operations Concerns Enclosure Footprints, Envelope Sizes Control System Issues Safety Concerns

    10. Trade Matrix
