Superconductivity - Part 7: Electronic characteristic measurements - Surface resistance of superconductors at microwave frequencies
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 milliohm at 10 GHz.

This European Standard was approved by CENELEC on 2006-11-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, the Czech

Foreword
The text of document 90/193/FDIS, future edition 2 of IEC 61788-7, prepared by IEC TC 90,
Superconductivity, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 61788-7 on 2006-11-01.
This European Standard supersedes EN 61788-7:2002.
Examples of technical changes made are:
– closed type resonators are recommended from the viewpoint of the stable measurements;
– uniaxial-anisotropic characteristics of sapphire rods are taken into consideration for designing the size
of the sapphire rods;
– recommended measurement frequency of 18 GHz and 22 GHz are added to 12 GHz described in
EN 61788-7:2002.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2007-08-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2009-11-01
with the EN have to be withdrawn
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 61788-7:2006 was approved by CENELEC as a European
Standard without any modification.
