ILIAS/N5:The GW antenna network

Raffaele FlaminioEGO and LAPP/CNRS

Summary- History- GWA Objectives & Contents- Management- Budget- Goals of this meeting

Paris, November 5th, 2004 2

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 1st 2004

• GWA Budget: 550 kEuros / ~ 200 scientists ….. Why do it ?A) GW experimental community enters the EU worldB) Do some coordinated work all together

Paris, November 5th, 2004 3

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)

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

Paris, November 5th, 2004 5

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

Paris, November 5th, 2004 6

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 boardensuring 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)

Paris, November 5th, 2004 7

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.Menzingero 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 11th, 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
