Low-temperature mechanical dissipation of thermally evaporated indium film for use in interferometric gravitational wave detectors. (13th May 2015) - Murray, Peter G
Abstract: Indium bonding is under consideration for use in the construction of cryogenic mirror suspensions in future gravitational wave detectors. This paper presents measurements of the mechanical loss of a thermally evaporated indium film over a broad range of frequencies and temperatures. It provides an estimate of the resulting thermal noise at 20 K for a typical test mass geometry for a cryogenic interferometric gravitational wave detector from an indium layer between suspension elements.
