Abstract

We report the status of the experimental effort devoted at improving the sensitivity and widening the band of the gravitational wave detector AURIGA. The focus is on an optimized setup of the capacitive resonant transducer, read by an improved dc-SQUID amplifier and on the implementation of an opto-mechanical resonant transducer. Both techniques, which are complementary, should lead to an improvement of the detector performances of at least two orders of magnitude in both energy sensitivity and bandwidth.
