On the mechanical quality factors of cryogenic test masses from fused silica and crystalline quartz
Anja Schroeter, Ronny Nawrodt, Roman Schnabel +11
Current interferometric gravitational wave detectors (IGWDs) are operated at room temperature with test masses made from fused silica. Fused silica shows very low absorption at the…

High-sensitivity tool for studying phonon related mechanical losses in low loss materials
Daniel Heinert, Anja Zimmer, Ronny Nawrodt +6
Fundamental mechanical loss mechanisms exist even in very pure materials, for instance, due to the interactions of excited acoustic waves with thermal phonons. A reduction of these…
