1. Paris, November 5th, 20041 ILIAS/N5: The GW antenna network Raffaele Flaminio EGO and LAPP/CNRS Summary - History - GWA Objectives & Contents - Management - Budget - Goals of this meeting

2. Paris, November 5th, 20042 GW net: Some history Several attempt to get funds from the EU in the 90’s failed In 2002 EU launched FP6 ApPEC launched a coordinated action in the European astroparticle physics community to prepare a proposal for an I3 called ILIAS (Integrated Large Infrastructures for Astroparticle Science) to be submitted to the EU Long process started - proposal preparation: 9/2002 – 3/2003 - proposal submission: March 2003 - partly approved in August 2003 (GW contents approved) - negotiations: fall 2003/spring 2004 - projects start: April 1 st 2004 GWA Budget: 550 kEuros / ~ 200 scientists ….. Why do it ? A) GW experimental community enters the EU world B) Do some coordinated work all together

3. Paris, November 5th, 20043 GW net: Main objectives Increase the level of European coordination in the field Enhance the performance of existing detectors Prepare the future of this discipline in Europe Provide a link between the various experimental projects and theoretical groups Encourage the researchers mobility Open existing facilities to more people from more countries Help the structuring an European GW research community - Ease the collaboration with related field such as Gamma-ray and Neutrino astronomy - Develop coordinated collaborations with non-European communities (USA, Japan, Australia)

4. Paris, November 5th, 20044 GW net: Proposed activities Develop the exchange of information among teams on items such as: - Commissioning and operation of existing detectors - Joint operation and data analysis - R&D for detectors upgrade and future projects Three working groups proposed : ­ WG1: Detectors commissioning and characterization ­ WG2: Joint operation of detectors and network data analysis ­ WG3: An European strategy for future detectors Beside working group activities: ­ Have bi-annual meetings involving the responsibles of the main projects and research poles ­ Organize an annual general meeting

5. Paris, November 5th, 20045 GW net: Objectives and Deliverables WG1 “Commissioning and operation of existing detectors” - Speed-up the VIRGO/GEO commissioning by means of a deeper collaboration - Provide inputs for establishing priorities in the short term improvement of existing detectors - Common characterization methodologies - Regular reports describing and comparing detectors performances WG2 “Joint operation of detectors and network data analysis” ­ Support joint observations among GW detectors and with gamma, neutrino and optical telescopes ­ Support the development of a network data analysis pipeline - Data analysis pipeline to perform joint analysis of data produced by a network of GW detectors ­ First astrophysical results deduced from joint observations WG3 “An European strategy for future detectors” ­ 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 strategic objectives over 10 years period

6. Paris, November 5th, 20046 GW net: Management structure Each working group typically consists of at least 10 experts One chairperson and co-chairperson per working group (task leaders) One executive board ensuring the coordination of the whole network formed by representative from main GW projects + working group conveners (~ 10 persons) One institution in charge of the budget administration (EGO)

7. Paris, November 5th, 20047 Executive board Set-up at the beginning of the project: * ILIAS-GWA coordinator: K. Danzmann (AEI Hannover) * Virgo representatives: R.Flaminio (CNRS LAPP), M.Punturo (INFN Perugia) * GEO representatives: B.Willke (AEI Hannover), S.Rowan (University of Glasgow) * Resonant antennas representatives: M.Cerdonio (INFN Padova), E.Coccia (INFN Roma) * LISA representative: S.Vitale (University of Trento) * Invited members: o EGO director: F.Menzinger o JRA3 Representative: G.Cagnoli (University of Glasgow) o Leaders of the three working groups (see below) o N6 Representative: ? Problem: attempts to establish a contact with the theoretical network have failed so far. Main outcome of the first EB meeting (Cascina, May 11 th, 2004): - working group members and chairmen (two/group) established - call for the annual general meeting in November (attached to the Virgo week in Orsay) - discussion on priorities (WG1) - decision to allow members of WG1 to access technical data of the all the antenna - good news: British and German groups asking support to participate to the upgrade of Virgo
