1  ET is a “design study” supported by the European Commission under the Framework Programme 7 (FP7)  It is a ~3 years project supported by EC with about 3 M€  It is started in May 2008 and will end in 2011 CSNII workshop - April, 06-07,

2  ET design study team is composed by all the major groups leading the experimental Gravitational wave search in Europe: CSNII workshop - April, 06-07, Participant no.Participant organization nameCountry 1European Gravitational ObservatoryItaly-France 2Istituto Nazionale di Fisica NucleareItaly 3Max-Planck-Gesellschaft zur Förderung der Wissenschaften e.V., acting through Max- Planck-Institut für Gravitationsphysik Germany 4Centre National de la Recherche ScientifiqueFrance 5University of BirminghamUnited Kingdom 6University of GlasgowUnited Kingdom 7NIKHEFThe Netherlands 8Cardiff UniversityUnited Kingdom

3  Light project  Really “conceptual”  4+1 working packages M. Punturo - Corso FP7, LNF Project Coordinator Scientific Coordinator WP1 coordinator Task responsible WP2 coordinator Task reponsible Task responsible WP3 coordinator Task responsible WP4 coordinator Task responsible Secretary J. Colas (EGO director) M. Punturo (INFN) H. Lück (MPG) J.v.d. Brand (Nikhef) F. Ricci (INFN) A. Freise (UNIBHAM) B. Sathyaprakash (Cardiff)

4  True link between the GEO and Virgo collaborations  Open, through the Science Team, to the world wide GW community M. Punturo - Corso FP7, LNF Executive board Governing Council Science Team Institutions Scientific community Project Project Coordinator Scientific Coordinator WP coordinators GEO,Virgo, ST representatives ( )

5 CSNII workshop - April, 06-07, Site and infrastructure Thermal noise of mirrors and suspensions / cryogenics Optical configuration Astrophysics issues Management J. v.d. BrandF. Ricci A. Freise B. S. Sathyaprakash J. Colas M. Punturo H. Lück

6 CSNII workshop - April, 06-07, Issues: Scientific Security Costs Legal … Figure: M.Lorenzini

7 CSNII workshop - April, 06-07, Thermo-Optic Noise Cryogenics Cryo-Materials Coatingless Mirrors

8 CSNII workshop - April, 06-07, Squeezed Light Non-Gaussian beams High power laser (1064nm, 1550nm)

9  Since GW detection is expected to occur in the advanced detectors, the ET science targets are mainly addressed to observational aspects:  Astrophysics:  Measure in great detail the physical parameters of the stellar bodies composing the binary systems  NS-NS, NS-BH, BH-BH  Constrain the Equation of State of NS through the measurement  of the merging phase of BNS  of the NS stellar modes  of the gravitational continuous wave emitted by a pulsar NS  Contribute to solve the GRB enigma  Relativity  Compare the numerical relativity model describing the coalescence of intermediate mass black holes  Cosmology  Measure few cosmological parameters using the GW signal from BNS emitting also an e.m. signal (like GRB)  Probe the first instant of the universe and its evolution through the measurement of the GW stochastic background  Astro-particle:  Contribute to the measure the neutrino mass 9

10  The ET science team is linking the GW community in Europe (and beyond) CSNII workshop - April, 06-07,  More than 110 physicists participated at the first ET general meeting (Nov.2008)

11  ET is inserted in the evolution scheme of the GW detectors in the world CSNII workshop - April, 06-07, ´06´07´08´09´10´11´12´13´14´15´16´17´18´19´20´21´22Virgo GEO LIGO LISA E.T.
