Figure 9From: Characterizing the attenuation of coaxial and rectangular microwave-frequency waveguides at cryogenic temperatures Power dependence of the attenuation constant of niobium-titanium coaxial line CC085NbTi. Attenuation constant α (dots) versus input power at the waveguide \(P_{\mathrm{in}}\) measured for frequencies between \(4.2\ \mbox{GHz}\) and \(12.7\ \mbox{GHz}\). The top axis indicates the average number of photons on resonance n̅.Back to article page
