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