The LISA optical bench — •Johanna Bogenstahl, Gerhard Heinzel, Michael Troebs, Christian Diekmann, Roland Fleddermann, Gudrun Wanner, Evgenia Granova, Marina Dehne, and Karsten Danzmann — Max Planck Institute for Gravitational Physics (Albert Einstein Institute) Callinstr. 38 D-30167 Hannover

The space-based gravitational wave detector Laser Interferometer Space Antenna (LISA) shall detect gravitational waves by measuring distance changes between its three satellites using interferometers. Currently, the first prototype of the so-called optical bench, that contains the interferometric setups for the lengths measurements of LISA, is being built for the European Space Agency (ESA). This optical bench will be tested at the Albert Einstein Institute and its functionality and sensitivity will be characterised. For this purpose, special tools and pre-experiments are necessary that will be discussed in the presentation.
