Abstract
We demonstrate how to machine a vibrating wire resonator for ultrasonic exc itations in gaseous and liquid helium. This novel resonator is designed as a nanoscopic mechanically flexible bridge machined out of a semiconductor/m etal hybrid. Quenching of the mechanical resonance around 100 MHz in gaseou s and liquid He-4 at 4.2 K is shown.
