If you have a question about this talk, please contact Dr Giovanni Barontini. Future gravitational-wave observatories need much improved sensitivity at low-frequencies, below 10Hz. For terrestrial instruments this in turn requires a substantial improvement in seismic isolation. I will talk about some of the limits to inertial sensing performance, and how Earth’s gravity affects this. We will see that tilt-to-translation coupling is the limiting factor in current systems and look at the current solutions. We plan to integrate homodyne phasemeters into conventional seismometer mechanics, and our early results show that the readout is sensitive enough to reach the mechanical thermal-noise floor over several octaves.
