Measurement of mechanical losses in bonding between components of test mass suspensions in cryogenic gravitational wave detectors
Galchenko L.D., Timokhin M.V., Mitrofanov V.P.
The article describes a method for studying mechanical losses in layers of low-melting metals and alloys used to bond suspension components of silicon test masses in cryogenic laser interferometric gravitational wave detectors. The obtained data will be used to assess the thermal noise of test masses of new-generation cryogenic gravitational wave detectors.
