2nd ET GENERAL WORKSHOP

14 Oct 2009, 10:45 → 16 Oct 2009, 15:40 Europe/Rome

Ettore Majorana Foundation

Harald Lueck (MPG Hannover), Michele Punturo (INFN Perugia and EGO)

Second General Meeting of the FP7 activity Einstein Telescope.

The 2nd annual meeting of the ET design study project will be organized in the "Ettore Majorana centre for scientific culture", Erice (Sicily-Italy), from the 14th to the 16th of October 2009. This is an important step toward the realization of a conceptual design of the 3rd generation gravitational wave observatory "ET". The progresses in the design will be reported by the scientists involved in the project and a large fraction of the time will be reserved to the discussion upon the several design possibilities identified in the last year of activity. Site requirements and selection, low frequency noise suppression technologies, detector topologies and QND techniques, science case will be discussed.
