The main characteristics of a large cryostat constructed by the gravitational wave group of the University of Rome, to cool down to liquid helium temperature Weber-type gravitational wave antennas, 3 m long and weighing up to 5000 kg, are presented. The cryogenic system has the following features: continuous operation time with an interval of 1 day every 54 days to refill the cryostat; small temperature gradients in the experimental chamber where the antenna is located, and very high acoustic and seismic insulation.

Abstract

The main characteristics of a large cryostat constructed by the gravitational wave group of the University of Rome, to cool down to liquid helium temperature Weber-type gravitational wave antennas, 3 m long and weighing up to 5000 kg, are presented. The cryogenic system has the following features: continuous operation time with an interval of 1 day every 54 days to refill the cryostat; small temperature gradients in the experimental chamber where the antenna is located, and very high acoustic and seismic insulation.
