Abstract

A network of five cryogenic 'bar' gw detectors has been in operation in the years 1997-2000. A generic coincidence search has been performed with such a network, under the International Gravitational Events Collaboration, IGEC, for millisecond burst gw signals. A triple coincidence within the network has a false alarm rate below 10^-2 y^-1. No triple coincidence was found over the 173.2 days during which at least three detectors where on the air and improved upper limits have been established for the gw flux on earth. The typical search thresholds of the detectors correspond to a neutron star - neutron star coalescence at 10 kpc distance. The network is currently under upgrade and it is expected to usefully complement, in searches for ms gw signals, the interferometric detectors under completion.
