ILIAS WP3 activities report and ET organization Harald Lück

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

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 YEAR 2 YEAR3 YEAR 4 YEAR 5 Tasks and Deliverables Q1 Q2 Q3 Q4 WP 3: A European strategy for future antennas Tasks: Working group and WEB site set-up Elaboration of short term improvement plan Presentation of short term plan to institutions Elaboration of ‘White book’ Presentation of ‘White book’ to institutions Writing of final report Deliverables: Annual Report WG chaired by H. Lueck (MPI Hannover) and M.Punturo (INFN Perugia) Palma de Mallorca, October 24th, 2005

‚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

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

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 2007-2008) Indicative budget for preparatory phase: 34 projects (budget 2007-2008) Closure: 2nd May 2007 First contracts to come into force before end 2007

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

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)

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
