We report on the present status of the resonant gravitational waves detectors EXPLORER and NAUTILUS operated by the ROG collaboration at CERN and at the INFN Frascati National Laboratories respectively. EXPLORER has been operating in continuous data taking for three years. NAUTILUS during 2002 underwent a partial overhaul of its read-out electronics. The results obtained since May 2003 show a considerable improvement in the performances of the apparatus. Both the detectors exhibit an unprecedented useful bandwidth: in over 30 Hz their spectral sensitivities are better than with a duty cycle only limited by cryogenic operations.

Abstract
We report on the present status of the resonant gravitational waves detectors EXPLORER and NAUTILUS operated by the ROG collaboration at CERN and at the INFN Frascati National Laboratories respectively. EXPLORER has been operating in continuous data taking for three years. NAUTILUS during 2002 underwent a partial overhaul of its read-out electronics. The results obtained since May 2003 show a considerable improvement in the performances of the apparatus. Both the detectors exhibit an unprecedented useful bandwidth: in over 30 Hz their spectral sensitivities are better than with a duty cycle only limited by cryogenic operations.File in questo prodotto:
