(contribution withdrawn) Pre-experiments for the LISA optical bench — •Christian Diekmann, Johanna Bogenstahl, Marina Dehne, Roland Fleddermann, Evgenia Granova, Gudrun Wanner, Michael Troebs, Gerhard Heinzel, and Karsten Danzmann — Max-Planck Institute for Gravitational Physics (Albert Einstein Institut), Hannover and QUEST, Leibniz University Hannover

The space-based gravitational wave detector Laser Interferometer Space Antenna (LISA) will detect gravitational waves in the frequency range between 0.03 mHz and 1 Hz. This will be done by measuring distance changes between free-flying testmasses. The key elements for these measurements are the so-called optical benches. A prototype of these benches is currently being built for the European Space Agency (ESA). For this purpose, several pre-experiments like the backlink fiber experiment had to be performed. This and other experiments will be discussed in the presentation.
