Interferometric gravitational wave detectors
Nuclear Physics B - Proceedings Supplements, 2005The 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 ...

Gravitational-Wave-Detector Events
Physical Review Letters, 1968A new series of experiments is described, involving two gravitational wave detectors spaced about 2 km. A number of coincident events have been observed, with extremely small probability that they are statistical. It is clear that on rare occasions these instruments respond to a common external excitation which may be gravitational radiation.

The ultracryogenic gravitational-wave detector AURIGA
Classical and Quantum Gravity, 1997The first run of the ultracryogenic resonant bar detector AURIGA is in progress. Diagnostics on the cryogenics, the data acquisition system and on the noise characteristics have been performed, with results in accord with the design. The bar reached 140 mK. In tests down to 2 K the detector noise was very close to `Brownian'.

Quantum Measurement in Gravitational-Wave Detectors
Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2006Laser interferometric gravitational-wave detectors measure tiny motions of macroscopic mirrors. Complex interferometer configurations and quantum optical techniques will be used to enhance sensitivity in future interferometers, which will reach and surpass the Standard Quantum Limit.

Advanced Gravitational Wave Detectors
2012After decades of research, physicists now know how to detect Einstein's gravitational waves. Advanced gravitational wave detectors, the most sensitive instruments ever created, will be almost certain of detecting the births of black holes throughout the Universe. This book describes the physics of gravitational waves and their detectors.

Low Temperature and Gravitation Wave Detectors
2014The success of a precision experiment is often associated to the use of low temperature techniques. In particular, when the thermal noise is a barrier for improving the experiment sensitivity, the cryogenics is crucial for beating this limitation. This strategy was applied in the case of the resonant gravitational wave detectors (GW) and now it is ...
