Proposed Projects
- Triple-pendulum mirror suspensions for the AEI 10m prototype interferometer:
Many optical components in the AEI 10m prototype interferometer need to be suspended by means of multiple pendula to provide the required seismic isolation. These suspension systems are mounted on actively-controlled, seimically-isolated benches inside a large ultra-high vacuum system. Each suspension needs to be electronically controlled in all six degrees of freedom. The suspension systems in use differ substantially according to their individual purpose. Steel wire triple pendula with two additional vertical stages support 5.6kg mirrors for the mode-cleaning/frequency-reference cavity. For the interferometer core optics, however, multiple cascaded pendula with an all-silica monolithic final stage carry 100g mirrors. One project would concern fabrication and installation of these suspension systems.

- Simulating LISA interferometric noise:
The project will be offered in the “Interferometry in Space” group of the Albert Einstein Institute in Hannover, Germany. The project will focus on simulations for the LISA mission, particularly on investigating and estimating interferometric noise. It is therefore ideal for students with an interest in computational physics.
