Abstract:

We present preliminary experimental results of room temperature tests of the gravitational wave antenna AURIGA. A capacitive resonant transducer is read by a low noise FET voltage linear amplifier. We have measured the characteristic parameters and the thermal brownian noise of the two fundamental mechanical modes.
