摘要：

We have instrumented a room temperature gravitational-wave antenna with a prototype bimodal capacitive transducer and a conventional FET amplifier. This transducer, realized with a steel intermediate resonator, provides mass ratios mu approximate to 10(-3) both with respect to the antenna and to the light-mass (27 g), mushroom-shaped, final resonator. We briefly report some remarks on the analysis of a three-mode system and the design charachteristics of the transducer. Finally, we show that the antenna has been operated for several days exhibiting a clean spectrum of thermal noise.
