Passive and active seismic isolation for gravitational radiation detectors and other instruments
Some new passive and active methods for reducing the effects of seismic disturbances on suspended masses are described, with special reference to gravitational radiation detectors in which differential horizontal motions of two or more suspended test masses are monitored. In these methods it is important to be able to determine horizontal seismic accelerations independent of tilts of the ground...
متن کاملLaser interferometer gravitational radiation detectors
Some techniques proposed or currently under development for detection of gravitational radiation by laser interferometers are reviewed, with particular emphasis on experiments covering the lower frequencies potentially accessible to ground based instruments.
متن کاملSeismic gravity-gradient noise in interferometric gravitational-wave detectors
When ambient seismic waves pass near and under an interferometric gravitational-wave detector, they induce density perturbations in the Earth, which in turn produce fluctuating gravitational forces on the interferometer’s test masses. These forces mimic a stochastic background of gravitational waves and thus constitute a noise source. This seismic gravity-gradient noise has been estimated and d...
متن کاملRadiation pressure and stability of interferometric gravitational-wave detectors.
The effect of radiation pressure on the stability of Fabry-Perot cavities with hanging mirrors is investigated. Such cavities will form an integral part of the laser interferometric gravitational-wave detectors that are being constructed around the globe. The mirrors are hung by means of a pendulum suspension and are locked by servo controls. We assume a realistic servo-control transfer functio...
متن کاملInternet Sensor Grid: Experiences with Passive and Active Instruments
The Internet is constantly evolving with new emergent behaviours arising; some of them malicious. This paper discusses opportunities and research direction in an Internet sensor grid for malicious behaviour detection, analysis and countermeasures. We use two example sensors as a basis; firstly the honeyclient for malicious server and content identification (i.e. drive-bydownloads, the most prev...
