ET: Baseline Concept
Underground location
– Reduce seismic noise
– Reduce gravity gradient noise
– Eases low frequency suspensions
Cryogenic
Overall beam tube length ~ 30km
Possibly Δ instead of L geometry

Science Team
Initially co-chaired by
– GEO spokesperson (Karsten Danzmann)
– Virgo spokesperson (Benoit Mours)
– Virgo-EGO Scientific Forum (VESF) coordinator (Francesco
Fidecaro)
Members
– Open to all members of GW community willing to contribute to
the DS
– Initial members will be the coordinators of the research groups
participating in the project and the main scientists of the
European gravitational wave community, indicated by the three
co-chairpersons
Meetings:
– must meet at least once a year, during the annual project plenary
meeting
Results to be achieved within the
next three years
Site selection: scientific, operative, legal,
financial, administrative
Seismic isolation, suspension, substrates,
coatings compatible with cryogenic
operation
Geometry, topology, configuration of IFO
with sensitivity < SQL; high power effects
Optimize scientific output and define DA
requirements
Contract number: RII3-CT-2004-506222
