摘要：

A very high quality factor sapphire dielectric resonator transducer is shown to be an extremely sensitive readout device for a resonant bar gravitational wave antenna. The transducer has the possibility of allowing operation below the standard quantum limit. Tests on a prototype transducer with quality factor up to Q similar or equal to 4 X 10(8) are described.
