Frequency and temperature dependence of quality factors of aluminum coaxial line CC141Al. (a) Measured internal (\(Q_{\mathrm{i}}\)) and (b) external quality factors (\(Q_{\mathrm{e}}\)) of coaxial line CC141Al versus frequency ν extracted from the spectra measured at RT (blue dots), at 4K (green dots) and BT (orange dots). The black lines are fits to the loss model discussed in the text.
