Resonant detectors for gravitational waves
Advances in Space Research, 2000Abstract For the first time a number of cryogenic resonant bar detectors of gravitational waves â ALLEGRO, AURIGA, EXPLORER, NAUTILUS, NIOBE â are on the air, in a continuous search for impulsive events. We present their capabilities, the foreseen upgrades and their role in a future global network with interferometric detectors.

Stabilized lasers for advanced gravitational wave detectors
Laser and Photonics Reviews, 2010 Second-generation interferometric gravitational wave detectors require high-power lasers with approximately 200 W of output power in a linear polarized, single-frequency, fundamental-mode laser beam.

The Virgo Gravitational Wave Detector
Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009The interferometer spectral-density of resolution is 6 x 10-231/ âHZ at 250 Hz.. We show the performances of mirror surfaces and coatings, laser frequency and amplitude stabilizations, interferometer control. We discuss advanced Virgo optical-technologies.

Resonant detectors for gravitational waves
Rendiconti del Seminario Matematico e Fisico di Milano, 1995The principles of the gravitational wave detection by means of resonant antennas are illustrated and a review of the resonant antenna experiments in the world is given. Possible plans for the future resonant antennas are indicated.

Gravitational Waves and Gravitational Wave Detectors
2020Just over 100 years ago, Albert Einstein published his General Theory of Relativity, which describes the interaction between matter, energy, space, and time and explains that the force of gravity is a result of the curvature of space and time (Einstein in Die feldgleichungen der gravitation.

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1979
Abstract As outlined in the preceding talk by Dr Thome, there are many possible sources of gravitational radiation, ranging from the interactions of supermassive black holes to supernova explosions of stars. Detection of such radiation could give information which cannot be obtained otherwise, for example on events occurring in the ...

Search for Gravitational Waves with Resonant Detectors
Advances in Space Research, 1989The search for Gravitational Waves began more than 40 years ago by initiative of Joe Weber. Since then two types of instrumentation have been developed: the large interferometers and the resonant detectors. In this review paper we deal with the resonant detectors: ALLEGRO, AURIGA, EXPLORER, NAUTILUS and NIOBE.

2020
In this chapter, we describe the laser interferometric gravitational wave detectors, like LIGO, which was used to make the first detection of gravitational waves in 2015. A gravitational wave passing through a circle of test particles will cause the shape to oscillate from a circle to an ellipse to a circle repeatedly, because of the periodic ...

New Class of Gravitational Wave Detectors
Nature, 1971IN a series of classic articles, Weber1â3 derived the equations of motion and the response of mass quadrupole detectors to tensor gravitational waves. He has also constructed a detector which is a cylindrical rod tuned to its fundamental longitudinal acoustic resonance. These devices (class 1 detectors) have a definite relationship between the resonant

The cryogenic detector of gravitational waves in Frascati
Journal of Physics E: Scientific Instruments, 1981The basic operational principles of a Weber type gravitational wave antenna are briefly described. The need to operate at low temperature to decrease noise implies the use of an efficient cryogenic apparatus. In particular the difficult task of having long and continuous operation time is aimed at.
