The automatic alignment system of GEO 600
Abstract This paper gives an overview of the automatic mirror alignment system of the modecleaner and main interferometer of the GEO 600 gravitational wave detector. In order to achieve the required sensitivity of the detector, the eigenmodes of all optical cavities have to be aligned with respect to the incoming beams (or vice versa) and kept aligned for long measuring periods. Moreover the be...

A world-wide network of interferometric gravitational wave detectors is currently operational. The detectors in the network are still in their commissioning phase and are expected to achieve their design sensitivity over the next year or so. Each detector is a complex instrument involving many optical, mechanical and electronic subsystems and each subsystem is a source of noise at the output of...
متن کاملCommissioning , characterization and operation of the dual - recycled GEO 600
The German–British laser-interferometric gravitational-wave detector GEO 600 is currently being commissioned as part of a worldwide network of gravitational-wave detectors. GEO 600 recently became the first kilometrescale interferometer to employ dual recycling—an optical configuration that combines power recycling and signal recycling. We present a brief overview 0264-9381/04/201737+09$30.00 ©...
متن کاملThe status of GEO 600
The GEO 600 gravitational wave detector located near Hannover in Germany is part of the LSC network of gravitational wave observatories. Since January 2006 the GEO 600 detector has participated in the S5 LSC science run and acquired sensitive and well-characterized science data with a high duty cycle. Until 1 October 2007, 415 days of science data with an average peak sensitivity of better than...
متن کاملThe modecleaner system and suspension aspects of GEO 600
GEO 600 uses two 8 m triangular ring cavities as a modecleaner system for the stabilization of the laser. To isolate the cavities with respect to the seismic noise the optical components are suspended as double pendulums. The resonances of these pendulums are damped by a local-control loop via magnet–coil actuators acting on the intermediate masses. The suspension scheme and the measured key da...
