(13) Wideband transducers (Padova) Work initiated in January 2004. Equipment necessary for the research available or on order. Internal staff available. EGO funded position (research assistant) expected to start in September 2004. Design goal is a mechanical amplifier able to perform at least a gain factor of 10 on the displacement in a wide bandwidth. Displacement measured by a Fabry-Perot resonator. Work started with a theoretical investigation by a PhD student and other researchers. Work ended in a design of a mechanical amplifier prototype together with its optical displacement transducer. Amplifier gain evaluated with a modelling software framework (Pro/Engineer - Pro/Mechanica). Localized rigid hinges could be a source of thermoelastic noise and need further evaluation.
