Implementation of a Stray Light Simulation for the Einstein Telescope — •Hanna Marozava1, Thomas Hebbeker1, and Achim Stahl2 — 1III. Physikalisches Institut A, RWTH Aachen University — 2III. Physikalisches Institut B, RWTH Aachen University
The Einstein Telescope (ET) will be the first gravitational wave detector of the third generation. Stray light is a severe problem for modern interferometers with high sensitivity, as another noise source contributing to the interferometer output. A simulation is required to tune detector settings to avoid undesirable light paths and to optimize the shape, number and position of baffles.
This talk will present the progress in developing a concept for the reduction of stray light in ET and first results.
