Transducer Charging Line Decoupling Capacitor Bar Amplifier Resonant Capacitive Transducer Istituto di Fotonica e Nanotecnologie, Trento STREGA kick-off meeting, 11-12 May 2004, Cascina M2 Advanced materials and techniques for resonant detectors • The sensitivity of the capacitive transducer increases with the electric field between the parallel plates. • Activity • Improvements by means of • special machining, cleaning and conditioning techniques • low loss dielectric coatings
Istituto di Fotonica e Nanotecnologie, Trento STREGA kick-off meeting, 11-12 May 2004, Cascina M2 Advanced materials and techniques for resonant detectors • Status • In the present capacitive transducers the maximum achieved electric field is about 107 V/m and no coating is used • Goal • 108 V/m between the electrodes at cryogenic temperatures if necessary with low loss coatings • First 18 months activity • In six months start of the room temperature tests on small area capacitors with high field. • In one year start of the coating dielectric loss measurement at room and at cryogenic temperatures.
