European Gravitational Observatory
Consortium founded in December 2000
Members :
INFN (50%) + CNRS (50%)
NIKHEF (associate)
Mandate :
“ensures the end of the construction of the antenna VIRGO, its
operation, maintenance and the upgrade of the antenna as well as its
exploitation; …
promotes an open co-operation in R&D; …
promotes the co-operation in the field of the experimental and
theoretical gravitational waves research in Europe;
promotes contacts among scientists and engineers, the dissemination
of information and the provision of advanced training for young
researchers.”

EGO-Virgo objectives (1)
2009 : 2nd Virgo Science Run
6 months data taking (July 2009 – January 2010)
Partially in coincidence with LIGO
Design sensitivity has been reached !
The interferometer proved to be very robust and stable
Significant limits on the Vela Pulsar
going to be published soon

EGO-Virgo objectives (2)
2010 : enlarge the volume of
observed universe
“Monolithic suspensions”
Increased “finesse”
Significant sensitivity improvement below ~400 Hz
A few months run in coincidence
with LIGO (August – October) : VSR3
Then “tuning” of the interferometer
to improve sensitivity
A key role by several italian groups
A responsive and efficient EGO support

2010-2015 prepare for the AdV era (2015 - …)
Increase by 1000 the volume
of observed universe
Several events per year expected
Enhanced LIGO/Virgo+

The “Monolithic Suspension” example
EGO funded R&D and fellowship program to develop the
technology (Glasgow, Firenze, Perugia, Roma I)
Construction of MS coordinated by P. Rapagnani
funded by EGO,
a lot of work by many laboratories: Lyon, Firenze, Perugia, Roma I
integration at EGO site (a lot of support from EGO)
Virgo decision to install MS based of expected performance
and scientific benefit (put forward to STAC and Council)
Commissioning of MS coordinated by E. Calloni
Roma I, Pisa, LAPP, EGO, …
Run strategy defined by Virgo (in consultation with LIGO)
Data taking
Virgo scientists (including EGO ones), strong EGO support : operators, data
transfers, maintenance, on-call …)

The AdV example
A large project (22 M€); a stronger organization put in place:
– Project defined by Virgo under supervision by the EGO Council
– Project Leader appointed by the Council for the duration of the construction
supported by a management team
– A WBS defined and an MoU signed
Investment cost through
the EGO budget
EGO responsibilities:
– Safety, Integration,
management, QC
– Infrastructure, vacuum,
injection

Virgo, a large infrastructure to run and maintain :
–
–
–
–
–
–
–
–
An efficient operator team
1 TB/day of data to collect, store and send out to off-line centers (CNAF and CC-IN2P3)
On-call service : 1 call/day (night and WE) to fix various problems
(security, air-conditioning, electricity, laser/optics, electronics, computing/network, vacuum …)
Specific high level expertise:
dedicated vacuum group
highly competent optics group
An endless fight : reducing environmental noise
A large system to maintain
~1000 orders/year
The right place to integrate components coming from scattered laboratories
EGO, a very responsive structure
–
J. Colas
i.e. new clean rooms, support for personnel i.e. MS, orders by Virgo people external to EGO

Computing
Computing at EGO:
– data acquisition, temporary storage, on-line processing (DQ, trigger)
– network, users support
– Audio and video conferencing
A crucial contribution by CC-Lyon, CNAF-Bologna
long term storage, off-line data analysis
– CNAF : Disk storage : 370 TB
– CNAF: Tape storage : 165 TB
– CNAF CPU: 300 kSI2k.days requested for 2010
Next JECC meeting on 21/10

contribute to the development of scientific knowledge
around Virgo.
a Forum to enlarge the research community around the
present Virgo collaboration.

Fellows and R&D
Fellowship program
– VESF, Data analysis, Commissioning, R&D, AdV
– More than 25 fellows currently supported
R&D program to prepare
for AdV
– Program will be strongly reduced to
give priority to AdV construction

Summary
An efficient, responsive and light structure to support Virgo
and promote European collaboration under supervision by
national institutions
EGO existence relies on Virgo/AdV success
The future of GW in Europe depends upon a stronger
collaboration between EU countries. EGO may prefigure the
required infrastructure.
