The 4th general ET meeting was held in Hannover on December 4 and 5 (2012) in the Seminar room of the Institut für Gravitationsphysik of the Leibniz Universität Hannover, Callinstr. 38, 30167 Hannover.
The Einstein Telescope Conceptual Design Study completed in May 2011. The next steps on the way to a detailed technical design study needed to be planned. At the 4th ET symposium we evaluated our current position, defined the needs for immediate R&D and design activities, and plotted the roadmap for the future.

The number of participants was limited to a maximum of 60 people due to space constraints. You could send a request for registration using this link:
