Interferometric gravitational wave detection at MIT.
Abstract
The problems involved in detecting gravitational waves by means of Michelson interferometry are reviewed, with a focus on ongoing efforts at MIT. The major fundamental and ubiquitous noise terms affecting the measurement are listed and briefly characterized, and particular attention is given to the present 1.5-m-arm interferometer, its 0-5-kHz noise spectrum, and the use of wide-band phase noise to reduce the ubiquitous noise due to light scattering. Also discussed are plans for a 5-m detector with large vacuum tanks and sputter-coated 8-inch-diameter 4-inch-thick Si mirrors.
