This standard BS EN 61788-15:2011 Superconductivity is classified in these ICS categories:
- 29.050 Superconductivity and conducting materials
- 17.220.20 Measurement of electrical and magnetic quantities
This part of IEC 61788 describes measurements of the intrinsic surface impedance (ZS) of HTS films at microwave frequencies by a modified two-resonance mode dielectric resonatormethod [13, 14]2. The object of measurement is to obtain the temperature dependence of the intrinsic ZS at the resonant frequenc y f0.
The frequency and thickness range and the measurement resolution for the intrinsic ZS of HTS films are as follows:
f requency: up to 40 GHz;
f ilm thickness: greater than 50 nm ;
m easurement resolution: 0 ,01 mΩ at 10 GHz.
The intrinsic ZS data at the measured frequency, and that scaled to 10 GHz, assuming the f2 rule for the intrinsic surface resistance RS (f < 40 GHz) and the f rule for the intrinsic surface reactance XS for comparison, shall be reported.
