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...
متن کاملMeasurement and simulation of laser power noise in GEO 600
This paper describes measurements and simulations related to power fluctuations of the laser light in the GEO 600 laser-interferometric gravitational wave detector. Measurements of the relative fluctuations of the light power at three different ports of the main interferometer are presented. In addition, measurements and simulations of the coupling transfer functions from power fluctuations at ...
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 status of GEO 600
The GEO 600 gravitational wave detector located near Hannover in Germany is part of an international network of gravitational wave observatories. As more and more of these detectors approach their final configuration, the focus is shifted from commissioning to detector characterization. At the moment, GEO 600, the first detector using advanced technologies such as dual recycling, is preparing f...
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...
