Abstract: The VIRGO experiment for the detection of gravitational waves is a big challenge both for physics and for technology. In particular, to satisfy the stringent requirements on the alignment and position of its suspended optical components to keep the detector at its point, a very complex distributed and supervised control system has been implemented. The current constraints are about 10(-10) m RMS for the longitudinal control ("Locking") and 10(-9) rad RMS for the angular degrees of freedom ("Alignment"). These requirements are satisfied by means of a specially designed hierarchical architecture for the local control system. It is necessary for managing the hard task of filtering all the environmental noises that limit the sensitivity of the interferometer. On the other end, the interferometer is supervised by a distributed global control system to maintain the detector fully operational. In this paper we describe the status of the real-time distributed control system of the Virgo interferometric detector of Gravitational waves, its performances and planned improvements.

Abstract: The interferometric gravitational wave detectors represent the ultimate evolution of the classical Michelson interferometer. In order to measure the signal produced by the passage of a gravitational wave, they aim to reach unprecedent sensitivities in measuring the relative displacements of the mirrors. One of them, the 3-km-long Virgo gravitational wave antenna, which will be particularly sensitive in the low-frequency range (10-100 Hz), is presently in its commissioning phase. In this paper the various techniques developed in order to reach its target extreme performance are outlined.

Abstract: International audience; In the framework of the expected association between gamma-ray bursts and gravitational wave signals, we present the preliminary results of an analysis aimed to search for bursts of gravitational waves associated with the long GRB 050915a. GRB 050915a was detected by the Swift satellite in 2005, when the Virgo detector was engaged in one of its science runs, namely the C7 run, during which the best sensitivity attained in 2005 was exhibited. This offered the opportunity for the first coincident analysis between a gamma-ray burst and the Virgo gravitational wave detector. Here we give an overview of this ongoing analysis, which at the end will play the role of a prototype, crucial in defining a methodology for gamma-ray burst triggered searches with Virgo. The final results of our analysis will also allow us to evaluate up to which level Virgo will be able to constrain the amplitude of the gravitational wave signal from a typical long gamma-ray burst.

Abstract: SELECTED PAPERS FROM THE 6TH EDOARDO AMALDI CONFERENCE ON GRAVITATIONAL WAVES, OKINAWA, JAPAN, 20-24 JUNE 2005; International audience; The automatic alignment system of the Virgo interferometer differs substantially from those used in similar experiments, since it uses a variant of the Anderson technique. This implies a completely different control topology with respect to other detectors, and the main feature is a strong coupling of different degrees of freedom in the optical signals. It also provides two extra output ports in which differential wave-front sensors can be placed, namely the light transmitted by the Fabry–Perot arm cavities. We report on the first experimental demonstration of this technique on a large scale recycled interferometer, and on the present status of the automatic alignment system.

Abstract: We report on the status of the Virgo detector, under commissioning. We will focus on the last year's activity. The two commissioning runs performed during 2005 allowed us to reach a sensitivity ofh∼ 6 × 10−22. The data obtained during the runs were used to test a few data analysis algorithms, namely coalescing binaries and burst searches. The main improvements made on the detector during this year will be described, as well as the plans and activities foreseen in the coming years.

Abstract: The interferometric gravitational wave detector Virgo is currently completing its commissioning phase and it is close to start scientific observations. Among the signals to be searched for, those emitted by coalescing binary systems are particularly promising and require a considerable computational effort to optimally search the parameter space. The Virgo collaboration has decided to implement an on-line analysis strategy capable of processing the interferometer data in-time. In this communication we present a component of the analysis pipeline, a parallel computing system based on the Message Passing Interface (MPI). We describe its capabilities, underlining its strength and flexibility, and we illustrate its relation with the other components of the pipeline. The on-line analysis chain, including the presented parallel system, has been run for the first time successfully during the Virgo commissioning run C5 in December 2nd to December 6th 2004.

Abstract: The response to a probe laser beam of a suspended, misaligned and detuned optical cavity is examined. A five degree of freedom model of the fluctuations of the longitudinal and transverse mirror coordinates is presented. Classical and quantum mechanical effects of radiation pressure are studied with the help of the optical stiffness coefficients and the signals provided by an FM sideband technique and a quadrant detector, for generic values of the product $\varpi \tau $ of the fluctuation frequency times the cavity round trip. A simplified version is presented for the case of small misalignments. Mechanical stability, mirror position entanglement and ponderomotive squeezing are accommodated in this model. Numerical plots refer to cavities under test at the so-called Pisa LF facility., Comment: 14 pages (4 figures) submitted to Phys. Rev. A

Abstract: International audience; The analysis of data taken during the C7 VIRGO commissioning run showed strong deviations from Gaussian noise. In this work, we explore a family of distributions, derived from the hypothesis that heavy tails are an effect of a particular kind of nonstationarity, heterocedasticity (i.e. nonuniform variance), that appear to fit VIRGO noise better than a model based on the assumption of Gaussian noise. To estimate the parameters of the noise process (including the heterogeneous variance) we derived an expectation-maximization algorithm. We show the consequences of non-Gaussianity on the fitting of autoregressive filters and on the derivation of test statistics for matched filter operation. Finally, we apply the new noise model to the fitting of an autoregressive filter for whitening of data.

Abstract: SELECTED PAPERS FROM THE 6TH EDOARDO AMALDI CONFERENCE ON GRAVITATIONAL WAVES, OKINAWA, JAPAN, 20-24 JUNE 2005; International audience; We present the status of the Virgo analysis pipeline dedicated to the search for coalescing binary signals, focusing on methods based on prior knowledge of the signal waveform. The pipeline includes two partially independent search methods: the multi-band template analysis (MBTA), which is original of Virgo and exploits the chirping behaviour of the signal, and a distributed implementation of the classical matched filter procedure (Merlino), based on robust MPI code. We discuss the application of the search methods to the analysis of data acquired during the Virgo commissioning run C5, which allowed us to perform tests and partially validate the methods and code.

Abstract: The study of the external influences from environmental disturbances is a fundamental issue in interferometric detection of gravitational wave, both in locking and in normal operation. Virgo is continuously monitored by a large number of environmental sensors, ranging from seismometers to microphones to electromagnetic probes, up to a weather station. Using data collected during the engineering runs, we have studied the features of the main external noise sources, and the way they interfere with Virgo operation and expected sensitivity. In this paper we present the preliminary results obtained.

Abstract: While the current interferometric gravitational wave detectors are approching their nominal sensitivity, the new generation of detectors is in an advanced design phase. The Virgo collaboration is defining now the path to arrive to a complete design of the advanced version of the detector within about two years. The upgrades needed to obtain a detector with improved sensitivity in a relatively short time are here discussed.

This result is achieved by hanging each mirror through an elastic suspension (Superattenuator), designed to filter mechanical vibrations in all the degrees of freedom. An experimental upper limit of the mirror residual seismic noise at a few Hertz is provided in this paper. This is lower than the thermal noise floor, expected to limit the antenna sensitivity in the low frequency range.

Abstract: In this paper we describe the architecture and the performances of a digital control system designed to damp the mechanical motion of a suspended mass. The position of the mass with respect to fixed reference points is acquired in real-time using classical optical levers, while the actuation is obtained through standard coil-magnet actuators. The number and the position of these devices allows the control of all the degrees of freedom of the mass. The algorithm developed to generate the control signals from the computed mass position error signals is based both on classical linear and non linear filtering techniques. The latter are necessary to manage the control of the mechanical system mainly in the first phase of control, when generally the position of the mass is far from the one chosen as reference and, therefore, nonlinearities may play a relevant role in the control.

Abstract: One of the main requirements of a digital system for the control of interferometric detectors of gravitational waves is the computing power, that is a direct consequence of the increasing complexity of the digital algorithms necessary for the control signals generation. For this specific task many specialized non standard real-time architectures have been developed, often very expensive and difficult to upgrade. On the other hand, such computing power is generally fully available for off-line applications on standard Pc based systems. Therefore, a possible and obvious solution may be provided by the integration of both the real-time and off-line architecture resulting in a hybrid control system architecture based on standards available components, trying to get both the advantages of the perfect data synchronization provided by the real-time systems and by the large computing power available on Pc based systems. Such integration may be provided by the implementation of the link between the two different architectures through the standard Ethernet network, whose data transfer speed is largely increasing in these years, using the TCP/IP, UDP and raw Ethernet protocols. In this paper we describe the architecture of an hybrid Ethernet based real-time control system prototype we implemented in Napoli, discussing its characteristics and performances. Finally we discuss a possible application to the real-time control of a suspended mass of the mode cleaner of the 3m prototype optical interferometer for gravitational wave detection (IDGW-3P) operational in Napoli.

Abstract: We present the last-stage suspension for the mirrors of the gravitational wave antenna Virgo. We studied some problems encountered during the commissioning of the Virgo central interferometer (CITF) and solved them with the aim of achieving the target sensitivity of the detector in its final configuration. We measured the effect of the holder on the internal motion of the mirror, and the residual nonlinear couplings between the electromagnetic actuators and the metallic parts present on the last-stage suspension. The limits experienced on the Virgo CITF have helped us to define some important modifications to be applied to the last-stage suspension. Moreover, we present the experimental study of west input mirror internal modes after it was dismounted from the Virgo central interferometer. The results were useful to identify, in the data of the engineering run 4 of the CITF, the thermal peaks of such a mirror.

Abstract: Continuously-driven microresonators, whose nonlinear response is dominated by the third-order Kerr nonlinearity, have proven to be valid alternatives to comb sources based on femtosecond mode-locked lasers [1]. More recenlty, the direct generation of optical frequency combs (OFCs) entirely through quadratic interactions has also been demonstrated in singly resonant cavity second harmonic generation (SHG) and in cw pumped nearly degenerate optical parametric oscillation [2,3]. Interestingly, theoretical studies on doubly resonant cavity SHG predicted the emergence of OFCs with a much lower threshold with respect to the singly resonant configurations, as well as rich nonlinear dynamics [4].

Abstract: We present a widely-tunable, singly-resonant optical parametric oscillator, emitting more than 1 W between 2.7 and 4.2 mu m, which is phase locked to a self-referenced frequency comb. Both pump and signal frequencies are directly phase-locked to the frequency comb of a NIR-emitting fs mode-locked fibre laser, linked, in turn, to the caesium primary standard. We estimate for the idler frequency a fractional Allan deviation of similar to 3 x 10(-12)tau(-1/2) between 1 and 200 s. To test the spectroscopic performance of the OPO, we carried out saturation spectroscopy of several transitions belonging to the nu(1) rovibrational band of CH3I, resolving their electronic quadrupole hyperfine structure, estimating a linewidth better than 200 kHz FWHM for the idler, and determining the absolute frequency of the hyperfine components with a 50-kHz-uncertainty.

Abstract: We report on efficient cw high-power second harmonic generation in a periodically poled LiTaO3 crystal placed in a resonant enhancement cavity. We tested three configurations, differing in the coupling mirror reflectivity, and a maximum conversion efficiency of about 76%, corresponding to 6.1 W of green light with 8.0 W of fundamental power, was achieved. This is, to the best of our knowledge, the highest cw power ever reported using a periodically-poled crystal in an external cavity. We observed photo-thermal effect induced by photon absorption at the mirrors and in the crystal, which however does not affect stable operation of the cavity. A further effect arises for two out of the three configurations, at higher values of the input power, which degrades the performance of the locked cavity. We suggest this effect is due to the onset of competing nonlinearities in the same crystal.

Abstract: The first low frequency facility (LFF) data are presented; the main purpose of the LFF is to study the pendulum thermal noise around 10 Hz. The displacement noise floor is at the level of 10−13 m Hz−1x/2 at 10 Hz, and at about 11 Hz enters the 10−14 m Hz−1/2 sensitivity region; this level is compatible with the electronic noise of the drivers of the actuators used to lock the apparatus. The calibration method and the seismic noise contribution are discussed.

Abstract: We experimentally demonstrate and theoretically explain the onset of optical frequency combs in a simple cavity-enhanced second-harmonic-generation system, exploiting second-order nonlinear interactions. Two combs are simultaneously generated around the fundamental pump frequency, with a spectral bandwidth up to about 10 nm, and its second harmonic. We observe different regimes of generation, depending on the phase-matching condition for second-harmonic-generation. Moreover, we develop an elemental model which provides a deep physical insight into the observed dynamics. Despite the different underlying physical mechanism, the proposed model is remarkably similar to the description of third-order effects in microresonators, revealing a potential variety of new effects to be explored and laying the groundwork for a novel class of highly efficient and versatile frequency comb synthesizers based on second-order nonlinear materials., 25 pages, 7 figures
