The AEI 10 m prototype interferometer — •Philip Koch — Albert Einstein Institut Hannover, Deutschland

Precision interferometry is the leading method for extremely accurate measurements in gravitational wave astronomy. The current generation of gravitational wave detectors is designed to be limited by quantum processes, whereas future gravitational wave detectors will use techniques to surpass the quantum noise. The AEI 10 m prototype interferometer will be a test bed for these techniques. It will be limited by quantum radiation pressure noise at frequencies between 20 and 200 Hz and by shot noise above 200 Hz. To reach these fundamental noise sources, all classical noise sources such as seismic, thermal and technical noise have to be suppressed. We present techniques of active and passive seismic isolation, frequency stabilization of our laser to a suspended reference cavity and an overview of the AEI 10 m prototype interferometer.
