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.
