Abstract

Status of the Feasibility Study of E-ELT, the ESO 42m Extreme Large Telescope, with emphasis on the Telescope architecture, manufacturing and erection. The new generation of Extremely Large Telescope, requires the identification of different technologies, in order to improve the stiffness to weight ratio of the structure, to introduce higher damping while maintaining under control the construction and maintenance costs. The identification of different construction technologies and the consequent development of the materials used, may allow to obtain a leading technological instrument able to meet also the most extreme scientific request, able to adapt to the new requests that might be raised along the life of the telescope. The control of the weight of the structure is extremely important for the dimensioning of the auxiliary structures, for energy management, and for the problems related to pre-assembly, disassembly in factory and erection on site.
