Abstract
We report on the results obtained with a cryogenic gravitational wave antenna equipped with a d.c. SQUID, operating at 2 K. During a period of a few days in April 1989the measured noise temperature (for short bursts of gravitational waves) was T e f f =7 mK corresponding to a sensitivity of h,2= 7. lo-''. This result allows to improve the previously published upper limits for the rate of gravitational wave bursts.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
