Talk Title |
A prototype of a cryogenic last suspension system. |
|
Abstract |
We have assembled and tested a full scale last stage suspension for the test masses of a cryogenic gravitational wave antenna. The fake mirror is a 20 kg silicon disk having the same dimensions as in the Virgo detector. The payload overall mass of 300 kg has been cooled in a large cryostat equipped with pulse tube cryocoolers. The thermal and mechanical results obtained in the first cooling run were compared to thermo-mechanical simulation. We present the preliminary results of these analyses. |
