DESCRIPTION

BS EN 61788-15:2011


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.
