London, October 26th, Status of the ILIAS-GWA network Raffaele Flaminio EGO and LAPP/CNRS Summary - Objectives & Contents - Means - Last year activities - Budget - Conclusions - Today agenda

London, October 26th, GWA net: Objectives GWA is a networking activity part of the ILIAS project and focus on GW antenna Objectives of this network - Increase the level of European coordination in the field - Help the enhancement of the performance of existing detectors - Prepare the future of this discipline in Europe - Open existing facilities to more people from more countries - Help the structuring an European GW research community A five years project - started in April will end in March 2009 GWA Budget: 550 kEuros / ~200 scientists in ~35 labs….. Why doing it ? A) Opportunity to have more coordination in Europe (and indeed it did happen) B) GW experimental community enters the EU world - more funds expected to come via the EU in some future - hope to have a design study funded by the EU in FP7

London, October 26th, GWA net: Participants LAPP Annecy, University of Barcelona, University of Birmingham, Cardiff University, EGO Cascina, INFN Ferrara., INFN Firenze, INFN Frascati, MPI Garching, INFN Genova, University of Glasgow, MPI Golm, MPI Hannover, LZH Hannover, Universitat Illes Balears, Universitat Jena, INFN Legnaro, Leiden University, Imperial College London, IPN Lyon, INFN Napoli, OCA Nice, LAL Orsay, INFN Padova, Universite Paris VI, ESPCI Paris, INFN Perugia, INFN Pisa, CNR Roma, INFN Roma1, INFN Roma2, Universita di Trento, CNR-ITC Trento, Universitat Tubingen, University of Warsaw 35 institutions, 7 countries (France, Germany, Great Britain, Italy, Netherlands, Poland, Spain) All members of Virgo, GEO, AURIGA, NAUTILUS/EXPLORER, MiniGRAIL collaborations Groups involved in R&D for future detectors (including most of the LISA European groups)

London, October 26th, GWA net: Contents 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 GWA activity based on three working groups: - WG1: Detectors commissioning and characterization (H.Grote, G.Losurdo) ­ WG2: Joint operation of detectors and network data analysis (G.Guidi, I.S.Heng) ­ WG3: An European strategy for future detectors (H.Lueck, M.Punturo) - Each working group typically consists of at least 10 experts - Two chairpersons per working group (task leaders) Beside working group activities: ­ Bi-annual meetings involving the responsibles of the main projects and research poles (Cascina May 2004, Prague February 2005, Perugia September 2005, Paris January 2006) ­ Annual general meeting open to all participants (common with STREGA) (Orsay 2004, Palma de Mallorca 2005, London today) ­ Common meetings with theorists (part of another network inside ILIAS) One institution in charge of the budget administration and WEB site hosting (EGO) -

London, October 26th, GWA net: Tools A small budget (550 kE in five years) to: Organize meetings / support participation to meetings - past and forthcoming meetings available at - always available: agenda and slides. Often also minutes. - proposal to have a documents archive (G. Cagnoli) Support short visits of scientists from one lab to another - infos available at Finance a very few fellowships - to support important network activities relevant to WG’s activities Trigger/finance outreach initiatives - not originally foreseen, ideas welcome

London, October 26th, Last year activities Organize meetings / support participation to meetings - Three WG1 meetings (Hannover, Frascati, Potsdam) - Two WG2 meetings (Florence, London) - ENTApP - GWA joint meeting on Gravitational Waves Sources and Observation (Paris) several positive feedbacks; Gianluca and Siong would like to organize a new one - Spinning Coalescing Binaries Workshop (Cardiff) - Two WG3 meetings (Frascati, Florence) - LIGO-Virgo workshop on Thermal Noise (Cascina) - GWDAW-VESF meeting (Isola d'Elba) Support short visits of scientists from one lab to another - Visit of a Virgo scientist to a GEO laboratory - Visit of a GEO scientist to the Virgo site - Participation of GEO scientists to Advanced Virgo Meetings Finance a very few fellowships - Fellowship to work on the AURIGA-ROG-Virgo joint data analysis (L. Baggio, just ended) - Fellowship to work on the GEO-Virgo joint commissioning effort (J. Smith, just started)

London, October 26th, Reports and Financing First financing received on July 2004 (3 months after the beginning of the project) First annual report report provided in June scientific report considered positively remark about publications list (please aknowledge EU-ILIAS support when possible) - a couple of minor modifications asked for the financial report Second pre-financing received on February 2006 (six months behind schedule!) Second annual report provided in June financial report considered positively (no remarks) - a couple of formal modifications asked for the scientific report (e.g. list of institutions involved) - more consistent modifications asked for other parts of ILIAS Waiting for the third pre-financing

London, October 26th, Budget Total budget: 550 kE (in five years) Received pre-financing (until today) EGO MPI TOTAL Amount spent (until today) Personnel 76336fellowships + administration Travels/Meetings180290not including VAT (real expenses ~ 210 kE) Indirect costs 24267used to cover ~ VAT + audit costs TOTAL Now waiting for the third pre-financing EGO anticipating the difference on its own budget

London, October 26th, Conclusions The GWA network is a tool available to everybody in the European GW community The GWA network is not a new collaboration nor a new GW detector project The network helped the coordination between the GW communities/projects active in the different European countries - triggered regular meetings between the GEO and Virgo commissioning groups - supported the first joint data analysis between interferometers and bars - launched the participation of GEO scientists in the design of Advanced Virgo - re-vitalized the European coordination in this field A few people are spending some amount of time to keep this tool alive (meeting organization, finance management and reports, scientific reports, …..) We hope it can be useful ….
