Future Gravitational Wave Detectors

2020
In this chapter, we discuss the future of gravitational wave detectors beyond the present second generation (2G). Several ambitious third generation (3G) projects which will significantly increase the reach of the detectors, through increased sensitivity as well as the ability to detect gravitational waves with lower frequencies, are being planned ...

Skyhook gravitational-wave detector

Nature, 1985
Gravitational waves in the 10–100-mHz band are inaccessible to Earth-based detectors because of seismic noise. Hitherto, the most sensitive detectors in this frequency band have been the Doppler tracking of interplanetary spacecraft1 and excitations of seismic motions in the Earth's surface2,3.

SPACECRAFT GRAVITATIONAL WAVE DETECTORS

International Journal of Modern Physics D, 2011
For detecting gravitational waves in space, deep-space laser ranging using drag-free spacecraft is a common method. Deep space provides a large arena and a long integration time. Laser technology provides measurement sensitivity, while drag-free technology ensures gravitational phenomenon to be measured with least spurious noises.

The Virgo Gravitational Wave Detector

Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009
The interferometer spectral-density of resolution is 6 x 10-231/ √HZ 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.

Interferometric gravitational wave detectors

International Journal of Modern Physics D, 2018
Gravitational wave detection has now entered the era in which signals are being found. It is timely, therefore, to review the current detectors and how they work. This review focuses on the dramatic arc that links the earliest clear understanding of gravitational wave detection with the current generation of detectors.

Cryogenic gravitational wave detectors

Physica B: Condensed Matter, 2000
Abstract Direct detection of gravitational waves is one of the great challenges of contemporary experimental physics. Gravitational waves provide unique information about the coherent bulk motion of the matter in the Universe and constitute a powerful testing ground for theories of gravity. After 40 years from the beginning of the experimental search

New Class of Gravitational Wave Detectors

Nature, 1971
IN a series of classic articles, Weber1–3 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

Spherical resonant-mass gravitational wave detectors

Physical Review D, 1995
A spherical gravitational wave antenna is a very promising detector for gravitational wave astronomy because it has a large cross section, isotropic sky coverage, and can provide the capability of determining the wave direction. In this paper we discuss several aspects of spherical detectors, including the eigenfunctions and eigenfrequencies of the ...

Interferometric gravitational wave detectors

Nuclear Physics B - Proceedings Supplements, 2005
The status, progress and plans for the interferometer gravitational wave detectors are presented. Interferometric gravitational wave detectors are complementary to the resonant detectors. Interferometers are broadband detectors covering a frequencies range of about 10 to 10 4 Hz and are generally sensitive to lower frequency sources or different ...
