1. ILIAS WP3 activities report and ET organization
Harald Lück

2. From 2004 to 2008
WG3 activities changed from technical issues and planning of 1.5 and 2nd generation detectors…
… to ideas and plans for a 3rd generation observatory
Main effort in the last year: ET Design study preparations

3. WG3: A European Strategy for Future Antennas
Transparency from 2005 (R. Flaminio)
Objectives and Delivearbles
- Determine objectives attainable trough short-term improvements
Draft a plan for an European network of GW detectors at the 2010 horizon
- Short term plan after 18 months
Long term plan: ‘White book’ defining the GW community objectives over 10 years period
YEAR 1

Annual Report
WG chaired by H. Lueck (MPI Hannover) and M.Punturo (INFN Perugia)
Palma de Mallorca, October 24th, 2005

4. ‚white book‘ -> ASPERA roadmap (Sept. 2007)
Permanent and postdocs
Construction and analysis
No distinction between engineers and physicists
Only the agents belonging to ASPERA or affiliated to it.
running experiments’ operation personnel included
PHDs excluded! This causes a non negligible error in estimating the financial impact.
Investment (R&D+ Construction + Commissioning +Operation costs)
No labour included, unless it is externalised labour (eg hire people to excavate a large cavity, prepare a large series of detectors etc)
Mostly money demanded from the agencies affiliated to ASPERA or EU
LISA not included
E.T. construction largely external costs

6. GraWiToN proposal
Initial Training Network under the Marie Curie actions
Training of young scientists on GW theory and experiments
Submitted in Sept08
It involves: France, Italy, Germany, UK, Poland and Spain
3M€ overall “typical” budget, 300k€ could be for EGO
Past the threshold but negligible chances of funding
STAC Nov2008

7. First call for proposals closing in spring 2007
Transparency from early 2007
For design studies, preparatory phase, and support actions
design studies: 35 M€
Support actions: 28 M€ (budget )
Indicative budget for preparatory phase:
34 projects (budget )
Closure: 2nd May 2007
First contracts to come into force before end 2007

8. ET: Einstein Telescope
A European 3rd Generation Gravitational Wave Observatory
Conceptual design study started May 2008
Money available from Sept on
(3M€ in total)

9. Need for new infrastructure
Existing facilities subject to high, unshieldable environmental noise levels (seismic, gravity gradient noise)
Data taking with advanced detectors incompatible with installation of third generation techniques in same envelope (requires long comissioning times)

22. WP5: Management Science team
Participation open to all scientists of the GW community willing to contribute to this project through their expertise and networking ability.
Co-chaired (first 6 months) by GEO spokesperson and by Virgo-EGO Scientific Forum coordinator
The Science Team is to keep continuous contact between the scientists working in the project with the larger GW scientific community and to allocate resources (man power and know-how) available outside the project for all the activities in the project that need external support
