Abstract

The ultra-cryogenic gravitational wave detector NAUTILUS is gathering data in Frascati (Rome), in its second science run since June 1998. The measured strain sensitivity at the two resonances is 4 × 10−22 Hz−1/2 over a bandwidth of 1 Hz and better than 3 × 10−20 Hz−1/2 over a band of about 25 Hz, with a duty cycle of about 80%, mainly limited by cryogenic operations. At the beginning of 2002, the detector will be upgraded with a new Al bar, transducer and SQUID, and will be tuned to the 935 Hz frequency of the recently discovered pulsar in SN 1987A. The future sensitivity of the detector is presented and discussed.
