The original mission
• WP3: An European Strategy for Future Antennas
– Plan the enhancement of the performances of the
European gravitational wave detectors and to organise
their collective operation.
– Objectives:
• To determine scientific objectives that could be attained through
short term improvements, optimisation and association of
detectors now available in Europe.
• To establish the bases for integrating existing and future
gravitational wave detectors in a coherent network.
• To draft a plan for a European network of gravitational wave
detectors at the 2010 horizon

Evolution of the activity
• During the last year of activity the
international scenario is evolved and this
affected the WP3 activity:
– Reduction of the number of projects based on
the resonant masses technology
– Incremental upgrades of the current
interferometric detectors
– Global vision of the network of interferometric
GW detectors

London October 26-27, 2006

Reduction of the number of
projects based on resonant masses
• Canceling of the SFERA project by INFN
• Support of the Dual project through an
R&D activity limited only to Italian labs
• Is it still possible to talk of a “networking”
mission of the WP3 in this field?
– Still items are shared with the other groups,
but, obviously, the activity has been oriented
preferably toward the ITF future

Incremental upgrade of the ITF
detectors
• GW interferometer defined an incremental
upgrade strategy
– Virgo  Virgo+  Advanced Virgo
– GEO600  GEO HF
– LIGO  Enhanced LIGO  Advanced LIGO
• Technical contents of these evolutions have
been discussed in the WP3 meetings
– High power laser and related optics
– Thermal noise in the suspended masses
– New optical schemes

…incremental upgrade of the ITF detectors
• WP3 supported the realization of the documents
describing part of these upgrades
– Deliverables of the WP3
– Members of the GEO600 collaboration contributed and
are contributing to the advanced Virgo Design
• Advanced Virgo white paper
• Guidelines for the Advanced Virgo R&Ds
• Nevertheless, the upgrade of each European
experiment is still a “private” business of the original
groups
– G.Losurdo & J.Hough talks about advVirgo & AdvLIGO
– A fully integrated effort is needed for a future 3rd
generation European detector

FP7: the last train!
• The Framework Programme 7 (FP7) is the most
important possibility that European groups, working
in GW experimental research, have to joint together
with a real common target.
• WP3 worked with the aim to catch this possibility
– 3rd generation technology have been discussed
• Cryogenic systems to reduce the thermal noise
– “Natural” link with STREGA
• Coating-less optics
• Squeezed states

…FP7: the last train!
• WP3 supported also the “political” discussion
– Meetings have been dedicated to the discussion of
“what we must do in the FP7” scenario
• H.Lueck will give a dedicated talk
– Some difficulties:
• Still friction against a real integration of the groups working in
this field
• huge working load caused by the current detectors
commissioning activity
• Global view, involving also our American
colleagues has been just started

WP3 team(s)
• The WP3 team is growing and having a variable
composition, depending on the subject under
discussion
• Official team:
– H.Lueck, M.Punturo
• K.Strain , R.Flaminio, V.Fafone, M.Bonaldi, A. de Waard, B.
Mours, G.Losurdo, A. Vicere, P.Hello
• Many important contributors:
• J.Hough, S.Rowan, G.Cagnoli, A.Fraise, A.Giazotto, F.Vetrano,
…..
• The dimension of the team is demonstrated by
huge participation to the WP3 meetings

2006 Meetings
• Three meetings in the last year:
– Frascati, 12-13 January
• INFN national laboratories
• http://www.ego-gw.it/ILIAS-GW/N5WP3Frascati06.html
• Presentation of the Virgo+ and Advanced Virgo
projects
– Thermal noise and High power laser working grouos
• Full day dedicated to the resonant detectors
evolution

… 2006 meetings
• Florence, 27-28 April
– http://www.ego-gw.it/ILIAS-GW/N5-WP3-WP2-Florence.html
– Organized in parallel and in collaboration with the
WP2
• Astrophysical issues MUST drive the development of the
future detectors
– 3rd generation technologies
• Cryogenics, Topologies, …
– Full day (WP2+WP3) dedicated to
• Scientific case for a 3rd generation detector
• Possible sensitivities
• (Animated) discussion on what to do in the FP7 scenario

… 2006 meetings
• EGO site, 6-7 October
–
http://wwwcascina.virgo.infn.it/collmeetings/DMwebpages/LIGO-Virgo-TNM/index.html
– Subject of the discussion has been the Thermal noise
in future detectors
• 2nd and 3rd generation
– First meeting investigating the “Global” view with our
LIGO colleagues (thanks to the EGO support)
• Still too early for the USA side to discuss about what next
advanced LIGO
– In any case, also in the FP7 framework, we must take
care of what is progressing in the rest of the world
(without waiting their decisions!)

Conclusions
• The first conclusion is that the “real work”
is starting now!
– FP7 is approaching
– The right place where to find an agreement
between all the European groups is WP3
– WP3 should promote the realization of the
new Design Study
– …. H.Lueck talk
