Paper Abstract

The next generation large telescope is expected to be on the order of a 20 to 50 meter diameter aperture. The facilities required for these large telescopes must be structurally efficient in design to be cost effective. A geodesic type, rotating aluminum dome is one possibility. A geodesic structure has the advantages of high specific strength and stiffness, easy of deployment to the site, rapid on-site assembly and installation in parallel with other telescope assembly tasks, and long life. This paper presents a feasibility study, cost estimates, and concept design for a 91 meters (300 feet) diameter geodesic aluminum dome suitable for the next generation large telescopes.
