Abstract

Cosmic ray showers interacting with the resonant mass gravitational wave antenna NAUTILUS, cooled down to 0.1 K, have been detected. The experimental results show large signals at a rate much greater than expected. Since August 2000 NAUTILUS has been running at T = 1.1 K (non-superconductor aluminium). There is evidence at the 3 standard deviation level that the rate of the large signals is dependent on the bar temperature. The rate is compatible with zero at a bar temperature of 1.1 K.
