This part of IEC 61788 describes measurement of the surface resistance of superconductors at microwave frequencies by the standard two-resonator method. The object of measurement is the temperature dependence of Rs at the resonant frequency.
The applicable measurement range of surface resistances for this method is as follows:
- Frequency: 8 GHz < f < 30 GHz
- Measurement resolution: 0,01 mΩ at 10 GHz
The surface resistance data at the measured frequency, and that scaled to 10 GHz, assuming the f2 rule for comparison, are reported.
