We describe a new type of torsional oscillator, suitable for studies of quantum fluids at frequencies of ∼ 100 Hz, but capable of reaching high velocities of up to several cm\,s−1. This requires the oscillator amplitude to exceed 100 μm, which is much too large for a conventional capacitor-driven device. We describe the new geometry for the oscillator, discuss its design, and report our initial tests of its performance.
