Abstract- "Next generation gravitational wave detectors are aiming for very low frequency stage operation. While advanced second generation instruments are limited to greater than 10 Hz operation, third generation projects are aiming to access the frequency region between 1 Hz to 10 Hz. To achieve sensitivity in this regime requires even lower frequency suspension and control stages than offered in current instruments. Here we demonstrate a Roberts linkage vibration isolation stage which may benefit such projects. It emulates a very low frequency pendulum in a compact stage, and has the added benefit of allowing low frequency position control using electrically controlled thermal expansion of its suspension wires. This method attenuates the seismic translational noise through actuation. We show here that using multiple parallel wires and a thermal offset the radiative response time can be increased, and that the corner frequency in the frequency response of the vibration isolation stage can be raised to 100 mHz or more.")
