scope:

This Standard 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 less than f less than 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.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:

lEC 61788-7: 2006 Superconductivity-Part 7: Electronic characteristic measurements-Surface resistance of superconductors at microwave frequencies (IDT)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.</<30 10 P at GHz mQ 0.01 resolution: Measurement GHz<>
