Dark Current Measurements on a Superconducting Cavity using a Cryogenic Current Comparator
R. Geithner, R. Neubert, W. Vodel +6
This paper presents non-destructive dark current measurements of superconducting TESLA cavities for superconducting LINACs. The measurements were carried out in a highly disturbed…
Measurements of a low temperature mechanical dissipation peak in a single layer of Ta2O5 doped with TiO2
I Martin, H Armandula, C Comtet +19
Thermal noise arising from mechanical dissipation in oxide coatings is a major limitation to many precision measurement systems, including optical frequency standards, high resolut…
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…
Mechanical losses in low loss materials studied by Cryogenic Resonant Acoustic spectroscopy of bulk materials (CRA spectroscopy)
Anja Zimmer, Ronny Nawrodt, Daniel Heinert +6
Mechanical losses of crystalline silicon and calcium fluoride have been analyzed in the temperature range from 5 to 300 K by our novel mechanical spectroscopy method, cryogenic res…
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…
