Design and control aspects of the AEI 10 m Prototype Interferometer — •Christian Gräf for the AEI 10m Prototype Team — Max-Planck-Institut für Gravitationphysik (Albert-Einstein-Institut), Institut für Gravitationsphysik, Leibniz Universität Hannover

The AEI 10 m Prototype Interferometer aims at beating the Standard Quantum Limit (SQL) at frequencies of about 100 Hz. To reach this ambitious goal all free design parameters of the underlying optical layout need to be thoroughly optimized with regard to bringing down classical noise, eventually allowing for operating the inteferometer with an exclusively quantum noise-limited sensitivity at frequencies in the measuring band. Retaining the feasibility of stably controlling the instrument in all relevant degrees of freedom, using digital feedback control, is a vital boundary condition for the experiment design. Due to the high complexity of the optical system, simulations play a key role in this process. This talk summarizes the status of design and control aspects of the prototype interferometer.
